Epipe Configuration on Nokia 7750 SR This article explains how to configure epipe between Nokia SR routers. The Cisco term is referred to as xconnect and the juniper term is L2circuit. Basic Theories: Epipe name itself identifies it's a point-to-point connection that uses Ethernet encapsulation to pass data bits/bytes between two endpoints. Service provider core act as a layer 2 switch for customer traffic. In other words, this helps to extend the IP segment of the same subnet shared between 2 different locations. Topology: ISIS Level 2 and LDP are preconfigured. let's explore the setup to configure epipe and initiate traffic between the 2 sites. LDP is used to signal the Service label between end nodes participating in epipe. Nokia: SAP-MTU and Service MTU play an important role. To bring up the epipe between 2 end nodes we need to take care of Service-MTU and Sap port MTU. SAP-port MTU and Service MTU should be the same if the encapsulation is null. If the encapsulation is do...
