Cisco ASR 5500 System Administration Guide

Sample Configuration
In this example, VRFs are configured on the ASR 5500 PE and pools are associated with VRFs. The exchanges
VPN routes with its IBGP peers (PE routers) and learns the MPLS paths to reach PEs via LDP. The forwards
the packets to the next-hop with two labels – an inner label learned from PE and an outer label learned from
the next hop IBGP neighbor.
