Hi every body!
I was reading about redundancy in switch supervisors.
There are different modes:
1) route processor redundancy(RPR)
2)Route processor redundancy(RPR+)
3)stateful switchover (SSO)
q1)I understand how these modes but my question is why one want to use any other mode but sso as fail over time is less than a second compared to other modes ?
q2) Should both supervisors be same?
Thanks a lot!
