I have 2 switches in a 2 member virtual chassis and one of them my
siteops knocked over. The use ISIS for the point to point links. BGP
to carry the networks. They take a default BGP route from both
routers and reflect a default to the top of rack 6 member virtual
chassis switch.
The 2 member switch receives 2 BGP routes from the to of rack virtual
chassis and reflects them to the routers.
When switch in the 2 member virtual chassis died, I experienced some
strangeness in routing:

Anyone have any idea what this could be? Also, even though the BGP
routes for the machines were in the routing table, I could access no
machines on the top of rack switch, nor the top of rack switch
itself. Running 9.3R4.
