vip redundancy

Hi,

I am planing to deploy second CSS on my disaster recovery site. Distance between two sites is about 300km, and i am planing to use VIP redundancy because those two css will be on the same subnet (VPLS trough MPLS core). Is any restrictions to vip redundancy in mean of delay, jitter etc?

Re: vip redundancy

The CSS uses a protocol similar to VRRP for communication/election between active/standby with a heartbeat every 1 sec.

After 3 missed heartbeat the CSS will failover.

You can adjust this timer with the following command

CSS11503-2(config)# vrrp-backup-timer ?

Integer value(Range: 3-120)

CSS11503-2(config)#

I believe that would be the only possible concern in your case.

Gilles.
