Chapter 15 Configuring EoMPLS

Configuring EoMPLS

The point-to-point VC requires you to configure VC endpoints at the two PE routers. Only the PE routers at the ingress and egress points of the MPLS backbone know about the VCs dedicated to transporting Layer 2 traffic. Other routers do not have table entries for these VCs.

Restrictions

When configuring an EoMPLS pseudowire on Cisco ASR 901, you cannot configure an IP address on the same interface as the pseudowire.

EoMPLS xconnect with VLAN range is not supported.

EoMPLS xconnect port with double tagged encapsulation is not supported.

When port channel is configured on MPLS core, the encapsulation ID should be equal to the bridge domain.

The encapsulation dot1ad command is not supported.

Configuring EoMPLS

Complete the following steps to configure EoMPLS:

 

Command

Purpose

Step 1

 

 

interface interface-id

Specify the interface, and enter interface configuration mode.

 

 

Valid interfaces are physical ports.

 

Example:

 

 

Router(config)# int gig 0/1

 

Step 2

 

 

service instance number ethernet [name]

Configure a service instance and enter service instance

 

 

configuration) mode.

 

 

The number is the service instance identifier, an integer from

 

Example:

1 to 4000.

 

(Optional) ethernet name is the name of a previously

 

Router(config-if)#service instance 101

 

ethernet

configured EVC. You do not need to use an EVC name in a

 

 

service instance.

Step 3

 

 

encapsulation {dot1q untagged}

Configure encapsulation type for the service instance.

 

 

dot1q—Configure 802.1Q encapsulation.

 

Example:

untagged—Map to untagged VLANs. Only one EFP per port

 

Router(config-if-srv)#encapsulation dot1q 51

can have untagged encapsulation.

 

 

Note The dot1ad keyword is not supported for the

 

 

encapsulation command in EoMPLS.
