Daniel & Authors I had a question related to the draft related to lab POC testing.
https://datatracker.ietf.org/doc/draft-voyer-spring-sr-replication-segment/ In the draft it states that SR replication using Tree SID to replication to leafs on a tree is only supported with a centralized PCE controller based model using BGP LS. I have an SR-MPLS Cisco VIRL POC test bed using XRV9000 nodes 7.0.1 using ISIS SR extensions where I have L3 vpn overlay and everything is working very well from a unicast perspective. No issues. I have LDP still enabled but via “SR-Prefer” am using SR-MPLS forwarding plane. I kept LDP enabled so I can use mLDP for LMDT label switched trees for multicast and technically that all MVPN procedures RFC 6513 6514 encap tunnel types should work for p-tree using mLDP forwarding plane for multicast while SR-MPLS is being used for unicast. I can get the LMDT core tree default and data mdt to build for MP2MP or P2MP tree but cannot get on the FEC root the MRIB state to build. Not sure why? Any ideas. Is there anything special I have to do for multicast to use the ldp mLDP extension data plane and not the SR-MPLS data plane. I think what’s happening is at the data plane forwarding level SR-MPLS data plane is being used instead of mLDP. I have a bunch of SR-TE policies in place with candidate dynamic and static ERO paths and that works well coloring the VRF steering. I was wondering if I can use SR-TE binding Sid with Static ERO loose path using prefix SID of egress PE to replicate to and build P2MP tree instantiation via SR-TE. Is that possible?
