OcNOS SP : Multi-Protocol Label Switching Guide : Multi-Protocol Label Switching Configuration : Inter-AS VPN Option-B Configuration
Inter-AS VPN Option-B Configuration
Inter-AS Option B is a more scalable solution compared to Option A. It does not require any VRFs on the ASBRs, it uses VPNv4 eBGP to exchange VPNv4 updates.
Single interface to connect the ASBRs.
Packets are sent labelled between the ASBRs.
No need for VRFs on the ASBR.
ASBRs must be directly connected.
Scales better than Option A.
