Cisco 10000 Series Router Software Configuration Guide
20-4
Configure IP routing in the core so that the PE routers can reach each other using IP.
Configure the label distribution protocol to be Label Distribution Protocol (LDP).
Configure label-switched paths (LSPs) between the PE routers. To enable dynamic MPLS labeling
on all paths between the imposition and disposition PE routers, use the mpls ip command.
Configure a loopback interface for originating and terminating Layer 2 traffic. Make sure the
PE routers can access the other router's loopback interface. Note that the loopback interface is not
needed in all cases. For example, tunnel selection does not need a loopback interface when AToM
is directly mapped to a TE tunnel.
For L2VPN: LS, it is not necessary to configure:
—The label distribution protocol to be Label Distribution Protocol (LDP).
—Label-switched paths (LSPs) between the PE routers using the mpls ip command.
