VPRN Service Configuration Commands

[no] policy vrrp-policy-id

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

This command associates one or more VRRP policies with the SRRP instance. A VRRP policy is a

collection of connectivity and verification tests used to manipulate the in-use priorities of VRRP and

SRRP instances. A VRRP policy can test the link state of ports, ping IP hosts, discover the existence

of routes in the routing table or the ability to reach L2 hosts. When one or more of these tests fail, the

VRRP policy has the option of decrementing or setting an explicit value for the in-use priority of an

SRRP instance.

More than one VRRP policy may be associated with an SRRP instance. When more than one VRRP

policy is associated with an SRRP instance the delta decrement of the in-use priority is cumulative

unless one or more test fail that have explicit priority values. When one or more explicit tests fail, the

lowest priority value event takes effect for the SRRP instance. When the highest delta-in-use-limit is

used to manage the lowest delta derived in-use priority for the SRRP instance.

VRRP policy associations may be added and removed at anytime. A maximum of two VRRP policies

can be associated with a single SRRP instance.

The no form of the command removes the association with vrrp-policy-id from the SRRP instance.

vrrp-policy-id — Specifies one or more VRRP policies with the SRRP instance.

priority priority

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

This command overrides the default base priority for the SRRP instance. The SRRP instance priority

is advertised by the SRRP instance to its neighbor router and is compared to the priority received

from the neighbor router. The router with the best (highest) priority enters the master state while the

other router enters the backup state. If the priority of each router is the same, the router with the

lowest source IP address in the SRRP advertisement message assumes the master state.
