AR10 must tag its internal IPv4 BGP prefixes with a BGP prefix SID
BR10 must be configured with an explicit IPv4 node SID.
CR10 must be configured with an explicit binding SID.
DR10 must be configured with explicit IPv4 adjacency SID.

CThe router ID used must be based on a 32-bit identifier value.
DParticipating interfaces are only required to be configured with the IPv6 protocol family and address.
