After the configurations, PE 3 and CE 1 can establish an LDP session and IS-IS neighbor relationship

between them.

NOTE:

The configurations for PE 4 and CE 2 are similar to those for PE 3 and CE 1. (Details not shown)

Perform configuration to allow CEs of the customer carrier to access PEs of the provider carrier,
and redistribute IS-IS routes to BGP and BGP routes to IS-IS on the PEs.

# Configure PE 1 and inject IS-IS routes.
