[c-nsp] IPv4 Multicast (Non-MVPN) MPLS - Single RP for multiple groups

[eyeballi77]

Hi folks,

..need some help..

I have tried to add add a new group (2) on an existing RP and working setup
used by group 1

Group 1 = 225.10.10.12
Group 2 = 225.10.10.13

Mode = sparse
RP mapping = static with ACL

The group 1 setup is build on VDSL/PPPoE into MPLS with GRE tunnel for
mcast with approx 15 sites working.
The group 2 setup is build on SVTI into MPLS PE to join the same vrf as the
group 1 setup.

The new site that is to use group 2 works fine using group 1 address, but
fails when trying to use the group 2 address.

I have narrowed the issue down to the PE, but wanted to reach out to see if
anyone can give me pointers..

below is the output of mstat for group 1

both groups use the same source server address so while working for group 1
there should be no changes required for group 2.  I have double checked all
the mroutes & the RP mapping ACL's etc.

appreciate any insights or pointers..
