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) within the
backbone to allow communication between CE 1 and CE 2.
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 PWs on ASBR 1.
•
Concatenate the two PWs on ASBR 2.
