Hello, I have MPLS L3 VPN. I have configured sparse mode on all P and PE routers and sparse-dense mode on all CE routers. On all routers I ran the command
ip pim autorp listener
and on one specific
ip pim send-rp-announce loopback 0 scope 30
ip pim send-rp-discovery loopback 0 scope 30
(I am not sure if this is right when I have MPLS L3 VPN). I have deafult MDT also.
When I try to ping a group address from the one CE router I have reply only from its ip address of f0/0 interface which is connected to the PE router and from the loopback address (they are in the group address). I don't receive reply from the other CE router which is in the same group. Where is my mistake?
Solved! Go to Solution.

I don't see the config I think you edit your comment, never mind,
https://www.cisco.com/c/en/us/support/docs/multiprotocol-label-switching-mpls/mpls/29220-multicast-mpls-vpn.html
from first look you need
in each PE two loopback one
1-for the Multicast RP for example Lo100
2- for MP-BGP update source between the PE and RR and other PE, for example Lo0
3- router-ID for tag switching is use Lo0
4- multicast send-RP use Lo100
use
ip tim bindir-enable instead of auto-rp
Hope this solve your issue.

Show me the config if you can.

Can I send it to you in private message? I don’t want to share it public cause it’s a project.
