Introduction

Peering is an agreement established between two networks or two Autonomous Systems (ASs) to exchange routing information using the BGP protocol as described in this guide.

Topology

The configuration examples in this guide display the connection of the Peer #1 Nokia SR OS ASN 64501 router (shown in the following figure) as a peering router to the rest of the network.
