I have MVPN service in MPLS network.
I recently connected new source of multicast into my CORE router which I also do an RP-candidate for groups of this source.
In my network I also have two other RPs with others groups on others routers .
The CORE router also is BSR candidate and it successfully mapped this two RPs, but it mapping for own RP does not work.
If i move BSR candidate on another router, which is not RP then all three RPs are mapped successfully.
IS it possible to have RP and BSR candidate in the same router?
IMHO in a global RP configuration all work fine. This issue observed only in vrf configuration.
ip pim vrf IPTV rp-candidate Port-channel1.329 group-list 99 interval 15
ip pim vrf IPTV bsr-candidate Port-channel1.328 0
Interface Po1.328 — receivers of multicast from RP[1-3] on the CORE router
Interface Po1.329 — source of multicast for RP on core router.

candidate bsr and RP will work in the same box,

But in fact they does not work.
