Did you look at the series of articles I wrote on our blog about RPF recovery using, among other things, mBGP?
Here are the links: http://blog.ipexpert.com/2010/12/13/multicast-reverse-path-forwarding-rpf/ http://blog.ipexpert.com/2010/12/15/multicast-rpf-failure-recovery-using-igp-routing/ http://blog.ipexpert.com/2010/12/27/multicast-rpf-failure-recovery-using-static-rpf/ http://blog.ipexpert.com/2010/12/29/multicast-rpf-failure-recovery-using-bgp/ Also, don't forget our recently released Multicast Operation and Troubleshooting book for more in-depth analysis of IP multicast: http://www.ipexpert.com/Cisco/mcast -- Marko Milivojevic - CCIE #18427 (SP R&S) Senior CCIE Instructor - IPexpert On Mon, Mar 19, 2012 at 05:41, Bodnar, Edward <[email protected]> wrote: > Anybody have a good example on how to fix RPF using MBGP.
