After you complete the previous configurations, the CEs should be able to learn the interface routes
from each other and ping each other.

Configuring 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 and CE 2
of Site 2 accesses the network through PE 2. PE 1 and PE 2 are different ASs. PEs in the same AS runs
IS-IS between them.
PE 1 and ASBR-PE 1 exchange labeled IPv4 routes by MP-iBGP. PE 2 and ASBR-PE 2 exchange labeled
IPv4 routes by MP-iBGP. ASBR-PE 1 and ASBR-PE 2 exchange labeled IPv4 routes by MP-eBGP.
ASBRs do not perform VPN target filtering for received VPN-IPv4 routes.
