Hi all, I am running bird 1.2.5 as a RS using classical design (one table per peer and one master global). I also added in addition a second table called "collector" that is just populated as the master table with other pipes protocols. Idea is that this table can be polled without touching the master table (never know) 1°) Pipe collisions: -------------------- I have this in my logs: 2011-02-01 10:32:50 <ERR> Pipe collision detected when sending X.Y.Z.T/zz to table collector X.Y.Z.T/zz being of course a valid prefix. Have you guys ever seen this. When does this occur? What is the consequence of a pipe collision? How can I troubleshoot? Note I do have that for IPv4 and IPv6. 2°) Missing LL IPv6 addresses: ------------------------------ I also have some problems with few IPv6 peers which seem not to send me LL addresses. 2011-01-31 16:48:12 <ERR> R655687: Missing link-local next hop address, skipping corresponding routes 2011-01-31 16:48:12 <ERR> R655687: - route xxxx:yyyy::/32 skipped xxxx:yyyy::/32 being a regular IPv6 prefix. The weird thing is that this peering is also flapping... The customer tells me he has the same config with other peerings without any problem. Any hint? Is bird doing more verifications than some vendor routers? Thanks for feedback and sorry if this has already been queried on some forums I'd have missed. -- ------------------------------------------------------------- Jerome Durand Responsable des services aux usagers Services operations & support manager Réseau National de Télécommunications pour la Technologie, l'Enseignement et la Recherche Tel: +33 (0) 1 53 94 20 40 | GIP RENATER Fax: +33 (0) 1 53 94 20 41 | 23-25 rue Daviel E-mail: jdurand@renater.fr | 75013 PARIS http://www.renater.fr | FRANCE --------------------------------------------------------------
