Re: BGP convergence problem

Dear Andy

This morning there was an ethernet loop problem on DECIX, causing many
BGP sessions to flap throughout the entire platform.
While this can happen, I am myself facing with BGP convergence
problems on our DECIX router (SUP720-3BXL with IOS SXI3).

De DECIX loop has been solved two hours ago, but my BGP sessions are
still flapping and not converging at all. This has been flooding our
logs, and is still going on:

route half or more of the peering-network to Null -> lowering bgp session up's.
(at the other side, your bgp-router seems to be overloaded).

Kind regards,
        Ingo Flaschberger
