Chapter 8 Configuring Ethernet Virtual Connections

How to Configure EVC Default Encapsulation

 

Command or Action

Purpose

Step 3

 

 

interface type number

Specifies an interface type and number, and enters interface

 

 

configuration mode.

 

Example:

 

 

Router(config)# interface

 

 

GigabitEthernet0/4

 

Step 4

 

 

service instance instance-idethernet

Creates a service instance on an interface and defines the

 

 

matching criteria.

 

Example:

instance-id—Integer that uniquely identifies a service

 

Router(config-if)# service instance 10

instance on an interface.

 

ethernet

 

Step 5

 

 

encapsulation default

Configures the default service instance.

 

Example:

 

 

Router(config-if)# encapsulation default

 

Step 6

 

 

xconnect peer-ip-address vc-id

Binds an attachment circuit to a pseudowire, and to configure an

 

encapsulation mpls

Any Transport over MPLS (AToM) static pseudowire.

 

Example:

peer-ip-address—IP address of the remote provider edge

 

(PE) peer. The remote router ID can be any IP address, as

 

Router(config-if-srv)# xconnect 1.1.1.1 100

long as it is reachable.

 

encapsulation mpls

vc-id—The 32-bit identifier of the virtual circuit (VC)

 

 

 

 

between the PE routers.

 

 

encapsulation—Specifies the tunneling method to

 

 

encapsulate the data in the pseudowire.

 

 

mpls—Specifies MPLS as the tunneling method.

 

 

 

Verifying EVC Default Encapsulation with Bridge-Domain

To verify the configuration of EVC default encapsulation with bridge-domain, use the show command shown below.

Router# show running-config interface gigabitEthernet 0/9

Building configuration...

Current configuration : 210 bytes
