Configuring an inter-domain multi-segment PW

Network requirements
PE 1 and ASBR 1 belong to AS 100. PE 2 and ASBR 2 belong to AS 200.
Set up an inter-domain multi-segment PW (a method for inter-AS Option B networking) between PE 1 and
PE 2, so CE 1 and CE 2 can communicate over the backbone.
Configure the inter-domain multi-segment PW as follows:
Configure LDP PWs between PE 1 and ASBR 1, and between PE 2 and ASBR 2, and configure
•
public tunnels through LDP to carry the PWs.
Configure an LDP PW between ASBR 1 and ASBR 2. Advertise labeled IPv4 routes between ASBR
•
1 and ASBR 2 through BGP to set up the public tunnel to carry the LDP PW.
Concatenate the two public tunnels on ASBR 1.
•
Concatenate the two public tunnels on ASBR 2.
