As per https://tools.ietf.org/html/rfc8402#section-3.1
“The context for an IGP-Prefix segment includes the prefix, topology, and algorithm. “ Clearly two different VRFs are different topologies. Therefore destinations in one VRF will have different SIDs from destinations in another VRF i.e., clearly the same prefix does not represent the same destination in this case.

Hi experts, Would like to know which SID can be used for the interfaces which are having same IP address and have different VRFs. Assume there are two interfaces on the same router. Both are having same IP address and they are differentiated using VRF. So, the config looks as shown below. eth1 ----> VRF1: 20.1.1.1/24<http://20.1.1.1/24> eth2 ----> VRF2: 20.1.1.1/24<http://20.1.1.1/24> Which SID can be used to represent these links ? Can we use AdjSID ? Thanks, Kaliyaperumal K
