No Pim Neighbor with MVPNs

Post by Guest » Thu Feb 24, 2005 6:16 am


PE1 is non SAFI capable running(12.3.16a), RR1 and PE2 are SAFI capable(12.2.31.SB11why isn't my RR "dumbing down the update" to PE1, is anyone aware of any bugs in either IOS?

If the PE is using mdt safi and route reflectors are using mdt safi & pre mdt safi in this case on PE you need to activate the ipv4 mdt for both the route reflectors so that PE can send the updates to RR1 with mdt safi and for RR2 it sends the update with extended 2:65500:1 community. In short we can upgraded RR1 is backward compatabile to the PE with respect to the mdt. Only one thing which we need to take is that to enable mdt safi for the non mdt PE.Please refer the full documenthttp://shivlu.blogspot.com/2009/02/upgradation-of-rr-to-mdt-safi.htmlregardsshivlu jain

MDT safi is used for mainly MVPN customers. If you are not going to activate the neighbor under ipv4 mdt in RR then it will dump the updates. If the mdt is activated under RR towards the non-mdt safi, it will not dump the updates.regardsshivlu jain

Thats the problem! The RR is configured for both vpnv4 and mdt towards both PEs, but the PE that doesn't support the MDT SAFI is not receiving it as a type 2 RD. Its like the RR is "not dumbing down" the new type MDT to old type 2 to the non MDT capable router. Hence why I think this is a bug on the RR. Its IOS is 122-31.SB11CheersMat
