Description (partial)

In an MVPN setup, observed that data mdt didnot forned because the ip multicast boundary on one core facing interface was affecting other core facing interface.
1. have two equal cost interfaces to core, Gig15/0 and Gig0/0/0
2. there should always be two equal cost paths to reach remote PE2. However Gig15/0 should be the rpf preferred interface.
3. have multicast boundary only on Gig0/0/0, which permits all groups except data-mdt group
4. shut Gig15/0. this will cause no data-mdt mdt formation over Gig0/0/0 because of the boundary command.
5. Now no-shut the Gig15/0 interface: rpf-preferred path. Although the incoming interface for data-mdt state is changed to Gig15/0, the join is still not sent.
