Example For Configuring Cfm Over Efp Interface With Cross Connect—Double Tag Vlan Cross Connect - Cisco ASR 920 Series Configuration Manual Ethernet Router

Configuring CFM over EFP Interface with Cross Connect—Double Tag VLAN Cross Connect
Command or Action
Example:
Router(config-if-srv)# encapsulation dot1q 100
second-dot1q 200
Step 6 rewrite ingress tag {push {dot1q vlan-id | dot1q vlan-id
second-dot1q vlan-id | dot1ad vlan-id dot1q vlan-id} | pop {1
| 2} | translate {1-to-1 {dot1q vlan-id | dot1ad vlan-id}| 2-to-1
dot1q vlan-id | dot1ad vlan-id}| 1-to-2 {dot1q vlan-id
second-dot1q vlan-id | dot1ad vlan-id dot1q vlan-id} | 2-to-2
{dot1q vlan-id second-dot1q vlan-id | dot1ad vlan-id dot1q
vlan-id}} [symmetric]
Example:
Router(config-if-srv)# rewrite dot1q double symmetric
Step 7
xconnect peer-ip-address vc-id {encapsulation {l2tpv3 [manual]
| mpls [manual]} | pw-class pw-class-name }[pw-class
pw-class-name] [sequencing {transmit|receive| both}]
Example:
Router(config)# xconnect 1.1.1.1 100 pw-class
vlan-xconnect
Step 8 cfm mep domain domain-name [up | down] mpid mpid-value
[cos cos-value]
Example:
Router# cfm mep down mpid 100 domain Core

CFM Configuration over EFP Interface with Cross Connect Feature
Purpose
Specifies the tag manipulation that is to be performed
on the frame ingress to the service instance.
Binds an attachment circuit to a pseudowire, and
configures an Any Transport over MPLS (AToM)
static pseudowire.
Configures a maintenance endpoint (MEP) for a
domain.
