Avaya recommends that you balance your VRRP masters between core switches. For example, say you have two VLANs on your core switches with VRRP enabled, VLAN 100 and VLAN 200. On core swith A, set the priority of VLAN 100 to 200, and on core switch B, set the priority of VLAN 200 to 200. This will set the VRRP master on VLAN 100 on core switch A, and the master for VLAN 200 will be on core switch B. This provides a balance.

It is also recommended that the VRRP advertise interval be set to 10 seconds, and the hold-down timer be set to 60 seconds.

If you can, run RSMLT. You will get better failover times.

I’m in the process of migrating an ageing L2 HP network over to Nortel, so your site has been an invaluable source of info over the last few months – Thanks!
The new Nortel network has three 8600’s in the core (with 5600 stacks at the edge) – what are your thoughts for setting VRRP priorities between them ?
