[j-nsp] VRRP tuning and scaling

[alaerte vidali]

Hi,

I believe you will face scalability issues, even though I can only affirm
this 100% in Cisco.

I suggest you consider not only normal periods of the network. In this case
probably it is ok.
But add to this all process you have, plus things like instabilities in
network (STP issues, link flapping...).
Then everything together can result in routers losing track of VRRP neighbor
packets due to the large number.

Br,
Alaerte
