The topology can be referred to the attachment. Check multicast VPN building with multicast software. After the configuration is finished, the service cannot be normally established and multicast VPN cannot be built. Check the route of NE80E and there is no opposite *.SG. The service cannot be normally established.
1. disp dev and the board is GRE.
2. Check mtunnel address configuration and it is unnumbered address.
