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

Figure 44: 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.
