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.
