interautonomous system (Inter-AS) network where Multilink PPP (MLP) is configured on the provider
edge-to-customer edge (PE-to-CE) links.
Figure 5: MLP on ASBR-to-PE Links in an MPLS VPN Inter-AS Network
The MPLS Multilink PPP Support feature supports MLP between Autonomous System Boundary Router
(ASBR) links for Inter-AS VPNs with Label Distribution Protocol (LDP) and with external Border Gateway
Protocol (eBGP) IPv4 label distribution.
How to Configure MPLS Multilink PPP Support
The tasks in this section can be performed on customer edge-to-provider edge (CE-to-PE) links, PE-to-provider
(P) links, P-to-P links, and Carrier Supporting Carrier (CSC) CE-to-PE links.
Creating a Multilink Bundle
Perform this task to create a multilink bundle for the MPLS Multilink PPP Support feature. This multilink
bundle can reduce the number of Interior Gateway Protocol (IGP) adjacencies and facilitate load sharing of
traffic.
