Brendan,

Could you comment a bit more on your config with this issue?  I just
attempted to replicate it on a 9.5R2 lab box and was unable.

I tested with OSPF running on an RVI with two upstream routers.
Changing trunks unrelated to OSPF didn't flap.  Neither did changing
trunks carrying the VLAN for my RVI.

I just want to make sure I'm 100% avoiding this potential issue.
