Configuration procedure
1. Configure MPLS L3VPN on the provider carrier backbone. Enable IS-IS as the IGP, enable LDP
between PE 1 and PE 2, and establish an MP-IBGP peer relationship between the PEs:
# Configure PE 1.

# Configure PE 2 in the same way that PE 1 is configured. (Details not shown.)
# On PE 1 or PE 2, execute the following commands:
{
Execute the display mpls ldp peer command to verify that an LDP session in Operational state
has been established between PE 1 and PE 2. (Details not shown.)
{
Execute the display bgp peer vpnv4 command to verify that a BGP peer relationship in
Established state has been established between PE 1 and PE 2. (Details not shown.)
{
Execute the display isis peer command to verify that the IS-IS neighbor relationship has been
established between PE 1 and PE 2. (Details not shown.)
2. Configure the customer carrier network. Enable IS-IS as the IGP, and enable LDP between PE 3 and
CE 1, and between PE 4 and CE 2:
# Configure PE 3.
