It can be upstream assigned or globally assigned (from DCB) as described in SR P2MP MVPN <https://datatracker.ietf.org/doc/draft-ietf-bess-mvpn-evpn-sr-p2mp/> draft. If present, the VPN SID is after the Replication SID. For SR-MPLS, the VPN SID SHOULD NOT be assigned from SRGB or SRLB since it is an overlay context,
