vasuramnet · ‎11-04-2009

Dear sir,

Failover time between primary and secondary central switch in a hirarchial network configuration in case of primary switch failure through HSRP .

what will be the time in case of VRRP.

in 2960 connected through multiple links through a central switch and spaning tree enabled what will be the time to switch over to the alternate links in case of primary link fails

plz give me any config examples

Hello Srini,

with default timers HSRP should converge in up to 10 seconds (three missed hellos from active router)

the same should happen for VRRP.

About STP:

if using uplinkfast the time is just the time to start to use the alternate uplink + the time to detect that the primary link failed.

by the way STP has to react faster then HSRP/VRRP

Hope to help

Giuseppe
