This command creates a Subscriber Router Redundancy Protocol (SRRP) instance on a group IP

interface. An SRRP instance manages all subscriber subnets within the group interfaces subscriber IP

interface or other subscriber IP interfaces that are associated through a wholesale/retail relationship.

Only one unique SRRP instance can be configured per group interface.

The no form of the command removes an SRRP instance from a group IP interface. Once removed,

the group interface ignores ARP requests for the SRRP gateway IP addresses that may exist on

subscriber subnets associated with the group IP interface. Then the group interface stops routing

using the redundant IP interface associated with the group IP interface and will stop routing with the

SRRP gateway MAC address. Ingress packets destined to the SRRP gateway MAC will also be

silently discarded. This is the same behavior as a group IP interface that is disabled (shutdown).

srrp-id — Specifies a 32 bit instance ID that must be unique to the system. The instance ID must also

This commands assigns a bi-directional forwarding (BFD) session providing heart-beat mechanism

for the given VRRP/SRRP instance. There can be only one BFD session assigned to any given

VRRP/SRRP instance, but there can be multiple SRRP/VRRP sessions using the same BFD session.

If the interface configured with BFD is using a LAG or a spoke-SDP, the BFD transmite and receive

intervals need to be set to at least 300ms.

BFD control the state of the associated interface. By enabling BFD on a given protocol interface, the

state of the protocol interface is tied to the state of the BFD session between the local node and the

remote node. The parameters used for the BFD are set via the BFD command under the IP interface.

The specified interface may not be configured with BFD; when it is, the virtual router will then

initiate the BFD session.

The no form of this command removes BFD from the configuration.

match the instance ID used by the remote router that is participating in the same SRRP context.

SRRP is intended to perform a function similar to VRRP where adjacent IP hosts within local

subnets use a default gateway to access IP hosts on other subnets.
