Chapter15 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
Example:
Router(config)# int gig 0/1
Specify the interface, and enter interface configuration mode.
Valid interfaces are physical ports.
Step 2
service instance number ethernet [name]
Example:
Router(config-if)#service instance 101
ethernet
Configure a service instance and enter service instance
configuration) mode.
• The number is the service instance identifier, an integer from
1 to 4000.
• (Optional) ethernet name is the name of a previously
configured EVC. You do not need to use an EVC name in a
service instance.
Step 3
encapsulation {dot1q | untagged}
Example:
Router(config-if-srv)#encapsulation dot1q 51
Configure encapsulation type for the service instance.
• dot1q—Configure 802.1Q encapsulation.
• untagged—Map to untagged VLANs. Only one EFP per port
can have untagged encapsulation.
Note The dot1ad keyword is not supported for the
encapsulation command in EoMPLS.
