[c-nsp] question about SSO

[Neil d]

Hi everyone,

I have a 7609s with 2 sup720, working in sso mode, now when the sup
switchover, according to cisco documentation, layer 2 traffic shouldnt be
interupted, but I noticed there's a rougly 0.6s gap in packet loss. (
traffic is in/out the same router, no other router involved). Is this
normal? I was thinking forwarding plan is not affected by the redundancy
switchover command. maybe I'm wrong?
