Are the two RRs configured with l2vpn AF please? Have you see the sessions bouncing on the me3600's Are you running code past 15.3(1)S that should be capable of BGP Enhanced Attribute Error Handling but now I'm not that sure if MEs do support it, This really looks like the second case I mentioned where RRs relied an UPDATE message that ME3600's perceived as malformed cause they could not parse through it. And either BGP enhanced error handling wasn't enabled or a mandatory attribute was affected they ought to reset the session over which such a malformed UPDATE message is received. Once the session is re-established they receive the update again and reset the session again -so the whole process loops. And only stops after the culprit attribute is removed from the update message. > I did "rollback 1" on the juniper 5048 and 104 and finally the me3600's were > able to settle down and establish bgp neighboring with the dual RR core and > all is well. > adam Adam Vitkovsky IP Engineer T: 0333 006 5936 E: [email protected] W: www.gamma.co.uk This is an email from Gamma Telecom Ltd, trading as “Gamma”.
