[j-nsp] VRRP max group limit?

[Gary Tate]

Sorry I misunderstood your question.  The limit or scaling is dependent 
on the platform, the RE and what may also be configured on the same box. 
  For example having BFD, an IGP adjacency and VRRP running over each 
vlan will effect the scaling numbers.

You can get official numbers from your local rep or PLM,
