Chapter 35 Layer 2 Control Protocol Peering, Forwarding, and Tunneling

How to Configure Layer 2 Control Protocol Peering, Forwarding, and Tunneling

Configuring Layer 2 Peering

The ASR 901 router supports layer 2 peering functionality on a per Ethernet Flow Point (EFP) basis. It supports a maximum packet rate of 10 packets ps (per interface) for a protocol, and 100 packets ps for all protocols (on all interfaces).

Table 35-1displays the supported defaults and configuration options for the Cisco ASR 901 router.

Complete the following steps to configure layer 2 peering:

Restrictions

If an EFP is configured with layer 2 peering, then L2CP packets coming on the EFP is sent to the CPU for local protocol processing.

SUMMARY STEPS

1.enable

2.configure terminal

3.interface type number

4.service instance id ethernet

5.encapsulation encapsulation-type

6.l2protocol peer [protocol]
