Vrrp Versus Rsmlt For Default Gateway Resiliency - Avaya 8800 Planning And Engineering

Figure 45: IPv6 VRRP configuration with SMLT
The backup master feature only supports the triangular SMLT topology.
Important:
Do not use VRRP backup master and critical IP at the same time. Use one or the other.
IPv6 VRRP and ICMP redirects
In IPv6 networks, do not enable ICMP redirects on VRRP VLANs. If you enable this option
(using the config ipv6 icmp redirect-msg command), VRRP cannot function. The
option is disabled by default.

VRRP versus RSMLT for default gateway resiliency

A better alternative than VRRP with BackupMaster is to use RSMLT L2 Edge. For Release 5.0
and later, Avaya recommends that you use an RSMLT L2 Edge configuration, rather than
VRRP with BackupMaster, for those products that support RSMLT L2 Edge.
