Chapter 16: Ipv6 Vrrp Configuration Using The Acli - Avaya ERS 8800 series Configuration Manual

Chapter 16: IPv6 VRRP configuration using
To provide fast failover of a default router for IPv6 LAN hosts, the Avaya Ethernet Routing Switch
8800/8600 supports the Virtual Router Redundancy Protocol (VRRP v3) for IPv6. VRRP supports a virtual
IPv6 address shared between two or more routers connecting the common subnet to the enterprise
network. VRRPv3 for IPv6 provides a faster switchover to an alternate default router than is possible using
the ND protocol.
Important:
An Avaya Ethernet Routing Switch 8800/8600 acting as a VRRP Master does not reply to SNMP Get
requests to the VRRP virtual interface address. It will, however, respond to SNMP Get requests to its
physical IP address.
When you use the Fast Advertisement Interval option to configure a master and backup switch, you must
enable the Fast Advertisement Interval option on both switches for VRRP to work correctly. If you configure
one switch with the regular advertisement interval, and the other switch with the Fast Advertisement
Interval, it causes an unstable state and drops advertisements.
VRRP configuration prerequisites
Ensure that RSMLT is not configured on the VLAN.
