LDP FEC Resolution Per Specified Community

LDP communities provide separation between groups of FECs at the LDP session level. LDP sessions are assigned a community value and any FECs received or advertised over them are implicitly associated with that community.

Note:

The community value only has local significance to a node. The user must therefore ensure that communities are assigned consistently to sessions across the network.

SR OS supports multiple targeted LDP sessions over a specified network IP interface between LDP peer systems, each with its own local LSR ID. This makes it especially suitable for building multiple LDP overlay topologies over a common IP infrastructure, each with their own community.

LDP FEC resolution per specified community is supported in combination with stitching to SR or BGP tunnels as follows.
