Chapter 14: 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.
To configure a VRRP interface, you can either configure the interface using the Configuration, IPv6, VRRP
path from the navigation tree, or by first selecting a port or VLAN and selecting the IPv6, VRRP path from
there.
Important:
An 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.
Prerequisites to VRRP configuration
• Assign an IPv6 address to the interface.
• Enable routing globally.
• RSMLT is not configured on the VLAN.
