OSPF shouldn't have to converge at all using NSF.

LDP is not SSO-aware in the 12.2SX code. You *WILL* lose adjacencies
performing a switchover if you're using MPLS. 12.2(33)SXH will
apparently fix this, or 12.2(33)SR on 7600s.

30 seconds? God, a full converge should take less than that (unless
you're running full or big BGP tables).

Silly question but - the routers at the other end are also SSO/NSF-aware
right? You are aware both ends need support?

Are you using the ports on the sup?

I've benched our sup720s performing a switchover in well under a second,
so you're definitely getting something wrong.
