INTER-AS COMMUNICATION SCENARIO ACROSS SERVICE PROVIDERS – OPTION B (2A)

This post is in continuation to last post on “Inter-AS Communication Scenario across Service Providers” where we discussed on “Option A – VRF-VRF” method in which the two autonomous systems of different service providers can interact to provide service to same customer locations. In this section , we will understand Option B-2A via Next-Hop-Self method of AS-AS communication.

Just to summarize – The need for Inter-AS communication arises when one service provider is having its customer base around the globe but doesn’t have connectivity all around the globe.In such cases the service provider take help of regional service provider to cater to their customer traffic in that region.

As a part of this document we will go ahead and configure Next-Hop -Self method between two AS and will leave the rest options for upcoming posts.
