remote}

This command designates a prefix as local or remote. This is used when multi-chassis synchronization is enabled.

Values

local — A prefix designated as local is always used to renew the existing addresses/prefixes or to assign a new one.
remote — A prefix designated as remote is used only to renew the existing DHCP leases. The new leases will be assigned from it only after the maximum-client-lead-time + partner-down-delay time elapses.

subnet

Syntax 

subnet {ip-address/mask string

hours

[0 — 24] the delay for the subnet to unbind in hours.

minutes

[0 — 59] the delay for the subnet to unbind in minutes.

seconds

[0 — 59] the delay for the subnet to unbind in seconds.

use-gi-address

Syntax 

use-gi-address [scopescope]

config>router>dhcp>server

This command enables the use of gi-address matching. By default, the scope is subnet and addresses are allocated only from the subnet where the gi-address belongs, even if the pool contains multiple other subnets. When the scope is pool, addresses are allocated from any subnet in the pool that contains the subnet where the gi-address belongs.

Default 

no use-gi-address

scope scope

Specifies if addresses are handed out for a certain subnet where the gi-address belongs to only or for all subnets part of the pool.

Values

subnet — Addresses are only handed out for the subnet where the gi-address is part of
pool — All subnets part of the pool which contain subnet where the gi-address is part of can hand out addresses.

use-pool-from-client

Syntax 

use-pool-from-client delimiter delimiter

use-pool-from-client

no use-pool-from-client

config>router>dhcp>server

This command enables the use of the pool indicated by DHCP client. When enabled, the IP address pool to be used by this server is the pool is indicated by the vendor-specific sub-option 13 of the DHCP option 82. When disabled or if there is no sub-option 13 in the DHCP message, the pool selection falls back to the “use-gi-address” configuration.

Default 

no use-pool-from-client

delimiter delimiter

A single ASCII character specifies the delimiter of separating primary and secondary pool names in Option82 VSO.

user-ident

Syntax 

user-ident user-ident

no user-ident

config>router>dhcp6>local-dhcp-server

This command configures the keys for identification of the DHCPv6 lease being held in the lease-database (for configured period after lease timeout). Subscriber requesting a lease via DHCPv6 that matches an existing lease based on this configured key is handed the matched prefix or address. This allows address and prefix“stickiness” for DHCPv6 assigned prefixes (IA_NA or PD).

Default 

duid

user-ident

Specifies the the user identification method

Values

duid — Specifies the IPv6 DHCP unique identifier from DHCPv6.
interface-id — Specifies the IPv6 interface-id option.
interface-id-link-local — Specifies the interface-id and link-local address.

use-link-address

Syntax 

use-link-address [scopescope]

no use-link-address

config>router>dhcp6>local-dhcp-server

If configured, local pool selection for v6 address or prefix assignment will use the configured link-address under relay configuration. The selected pool will contain a prefix covering the link-address. The scope option defines the scope for the match. With scope subnet, the prefix or address selection is limited to the prefix in the pool that covers the link-address. With scope pool, all the prefixes in the selected pool are eligible for assignment.

Default 

scope subnet

scope scope

Specifies the scope of the IP address selection.

Values

subnet — Specifies that the prefix or address selection is limited to the prefix in the pool that covers the link address.
pool — Specifies that all prefixes in the selected pool are eligible for assignment.

dhcp

Specifies that the DHCP relay will forward requests to the DHCP server(s).

pppoe

Specifies that PPPoE will attempt to request an IP address for a PPPoE client from the DHCP server(s)ly assigned to PPPoE node.

lease-populate

Syntax 

lease-populate [nbr-of-leases]

lease-populate [nbr-of-leases] l2-header [macieee-address]

no lease-populate

config>service>vprn>interface>dhcp

config>service>vprn>sub-if>group-if>dhcp

config>service>vprn>interface>dhcp

DHCP snooping must be explicitly enabled (using the snoop command) at all points where DHCP messages requiring snooping enter the VPLS instance (both from the DHCP server and from the subscribers). Lease state information is extracted from snooped DHCP ACK messages to populate lease state table entries for the SAP.

The optional number-of-entries parameter is used to define the number lease state table entries allowed for this SAP or IP interface. If number-of-entries is omitted, only a single entry is allowed. Once the maximum number of entries has been reached, subsequent lease state entries are not allowed and subsequent DHCP ACK messages are discarded.

The retained lease state information representing dynamic hosts may be used to:

Default 

no lease-populate

nbr-of-leases

Specifies the number of DHCP leases allowed.

l2-header

Indicates a mode of operation where anti-spoof entry associated with the given DHCP state is created based on the MAC address from the Layer 2 header. The Layer 2 header flag is not set by default.

mac

Specifies that the provisioned MAC address will be used in the anti-spoofing entries for this SAP. The parameter may be changed mid-session. Existing sessions will not be re-programmed unless a tools perform command is issues for the lease.

lease-populate

Syntax 

lease-populate [nbr-of-entries]

lease-populate [nbr-of-entries] l2-header [macieee-address]

no lease-populate

config>service>vprn>if>dhcp

config>service>vprn>sub-if>dhcp

config>service>vprn>sub-if>grp-if>dhcp

This command enables dynamic host lease state management for VPLS SAPs and VPRN or IES IP interfaces. Lease state information is extracted from snooped or relayed DHCP ACK messages to populate lease state table entries for the SAP or IP interface.

The optional number-of-entries parameter defines the number lease state table entries allowed for this SAP or IP interface. If number-of-entries is not specified, only a single entry is allowed. Once the maximum number of entries has been reached, subsequent lease state entries are not allowed. If lease state population is enabled and an entry cannot be retained in the table, the DHCP Relay or DHCP snoop function will prevent the far-end host from receiving the DHCP ACK message.

The retained lease state information representing dynamic hosts may be used to populate a SAP based anti-spoof filter table to provide dynamic anti-spoof filtering. Anti-spoof filtering is only available on VPLS SAPs, IES IP interfaces terminated on a SAP or VPRN IP interfaces terminated on a SAP.

The retained lease state information representing dynamic hosts may be used to populate the system’s ARP cache based the arp-populate feature. ARP-populate functionality is only available for static and dynamic hosts associated with IES and VPRN SAP bound IP interfaces.

The retained lease state information representing dynamic hosts may be used to populate managed entries into a VPLS forwarding database. VPLS forwarding database population is an implicit feature that automatically places the dynamic host’s MAC address into the VPLS FDB. When a dynamic host’s MAC address is placed in the lease state table, it will automatically be populated into the VPLS forwarding database associated with the SAP on which the host is learned. The dynamic host MAC address will override any static MAC entries using the same MAC and prevent dynamic learning of the MAC on another interface. Existing static MAC entries with the same MAC address as the dynamic host are marked as inactive but not deleted. If all entries in the lease state table associated with the MAC address are removed, the static MAC may be populated. New static MAC definitions for the VPLS instance may be created while a dynamic host exists associated with the static MAC address.

Default 

not enabled

nbr-of-entries

Defines the number lease state table entries allowed for this interface. If this parameter is omitted, only a single entry is allowed. Once the maximum number of entries has been reached, subsequent lease state entries are not allowed and subsequent DHCP ACK messages are discarded.

lease-populate

Syntax 

lease-populate [nbr-of-leases]

no lease-populate

config>service>vpls>sap>dhcp

config>service>ies>if>sap>dhcp

config>service>ies>if>ipv6>dhcp-relay

This command specifies the maximum number of DHCP or DHCP6 lease states allocated by the DHCP relay function, allowed on this interface.

The no form of the command disables dynamic host lease state management.

Default 

no lease-populate

nbr-of-leases

Defines the number lease state table entries allowed for this interface. If this parameter is omitted, only a single entry is allowed. Once the maximum number of entries has been reached, subsequent lease state entries are not allowed and subsequent DHCP6 ACK messages are discarded.

match-circuit-id

Syntax 

[no] match-circuit-id

config>service>ies>sub-if>grp-if>dhcp

config>service>vprn>sub-if>dhcp

config>service>vprn>sub-if>grp-if>dhcp

This command enables matching Option 82 circuit ID on relayed DHCP packet matching.

For Routed CO, the group interface DHCP relay process is stateful. When packets are relayed to the server the virtual router ID, transaction ID, SAP ID, and client hardware MAC address of the relayed packet are tracked. When a response is received from the server the virtual router ID, transaction ID, and client HW MAC address must be matched to determine the SAP on which to send the packet out. In some cases, the virtual router ID, transaction ID, and client HW MAC address are not guaranteed to be unique.

When the match-circuit-id command is enabled this part of the key is used to guarantee correctness in the lookup. This is only needed when are dealing with an IP aware DSLAM that proxies the client HW mac address.

Default 

no match-circuit-id

option

Syntax 

[no] option

config>service>vpls>sap>dhcp

config>service>ies>interface>dhcp

config>service>vprn>interface>dhcp

config>service>vprn>sub-if>dhcp

config>service>vprn>sub-if>grp-if>dhcp

config>service>ies>sub-if>grp-if>dhcp

This command enables DHCP Option 82 (Relay Agent Information Option) parameters processing and enters the context for configuring Option 82 sub-options.

The no form of this command returns the system to the default.

Default 

no option

action

Syntax 

action {replace ”.

In order to send a tuple in the circuit ID, the action replace command must be configured in the same context.

If disabled, the circuit-id sub-option of the DHCP packet will be left empty.

The no form of this command returns the system to the default.

Default 

circuit-id

ascii-tuple

Specifies that the ASCII-encoded concatenated tuple consisting of the access-node-identifier, service-id, and interface-name is used.

vlan-ascii-tuple

Specifies that the format will include VLAN-id and dot1p bits in addition to what is included in ascii-tuple already. The format is supported on dot1q and qinq ports only. Thus, when the Option 82 bits are stripped, dot1p bits will be copied to the Ethernet header of an outgoing packet.

circuit-id

Syntax 

circuit-id [ascii-tuple keep}

no action

config>service>vprn>if>dhcp>option

config>service>vprn>sub-if>grp-if>dhcp>option

This command configures the processing required when the SR-Series receives a DHCP request that already has a Relay Agent Information Option (Option 82) field in the packet.

The no form of this command returns the system to the default value.

Default 

Per RFC 3046, DHCP Relay Agent Information Option , section 2.1.1, Reforwarded DHCP requests, the default is to keep the existing information intact. The exception to this is if the giaddr of the received packet is the same as the ingress address on the router. In that case the packet is dropped and an error is logged.

replace

In the upstream direction (from the user), the existing Option 82 field is replaced with the Option 82 field from the router. In the downstream direction (towards the user) the Option 82 field is stripped (in accordance with RFC 3046).

drop

The packet is dropped, and an error is logged.

keep

The existing information is kept in the packet and the router does not add any additional information. In the downstream direction the Option 82 field is not stripped and is sent on towards the client.

The behavior is slightly different in case of Vendor Specific Options (VSOs). When the keep parameter is specified, the router will insert his own VSO into the Option 82 field. This will only be done when the incoming message has already an Option 82 field.

If no Option 82 field is present, the router will not create the Option 82 field. In this in that case, no VSO will be added to the message.

match-circuit-id

Syntax 

[no] match-circuit-id

config>service>vprn>sub-if>grp-if>dhcp

This command enables Option 82 circuit ID on relayed DHCP packet matching. For routed CO, the group interface DHCP relay process is stateful. When packets are relayed to the server the virtual router ID, transaction ID, SAP ID, and client hardware MAC address of the relayed packet are tracked.

When a response is received from the server the virtual router ID, transaction ID, and client hardware MAC address must be matched to determine the SAP on which to send the packet out. In some cases, the virtual router ID, transaction ID, and client hardware MAC address are not guaranteed to be unique.

When the match-circuit-id command is enabled this part of the key is used to guarantee correctness in our lookup. This is really only needed when dealing with an IP aware DSLAM that proxies the client hardware MAC address.

Default 

no match-circuit-id
