[j-nsp] ex4200 routing weirdness

[Cord MacLeod]

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.
