Re: MVPN study material for CCIE-SP

MVPN is not that difficult if you KNOW multicast in your heart ;-) If
you really know how PIM works and you are sure that your provider (or
multiple providers) have multicast working perfectly. Actually your
MPLS VPN's have little to do with the working of MVPN, as it doesn't
uses MPLS, but dynamically builds a multipoint GRE tunnel.

So KNOW how multicast works in your provider network, KNOW how it
works in your PE-CE network and then it's just 1 command and it
works :-)

(don't forget to enable multicast on your BGP next-hop, almost always
your Loopback)

Check RPF information (show ip rpf), as that can behave a little
different on the S-train IOS.

My advice is to dedicate a couple labs to it, as multicast is quite a
topic in the SP lab, but once you got it down, there is not much to
it :-)
