Verifying the configuration
After the configurations, the CEs can learn the interface routes from each other and ping each other.
Configuring MPLS L3VPN inter-AS option B
Network requirements
Site 1 and Site 2 belong to the same VPN. CE 1 of Site 1 accesses the network through PE 1 in AS 100,
and CE 2 of Site 2 accesses the network through PE 2 in AS 600.
PEs in the same AS run IS-IS.
PE 1 and ASBR-PE 1 exchange VPNv4 routes through MP-IBGP. PE 2 and ASBR-PE 2 exchange VPNv4
routes through MP-IBGP. ASBR-PE 1 and ASBR-PE 2 exchange VPNv4 routes through MP-EBGP.
ASBRs do not perform route target filtering of received VPN-IPv4 routes.
