DETAILED STEPS

Verifying an R-L2GP Configuration

The following examples show how to use the show commands to verify an R-L2GP configuration:

Router# show spanning-tree pseudo-information 46 configuration

remote_id 53

mst_region_id 0, port_count 2, update_flag 0x0

mrecord 0x3AF841EC, mrec_count 3:

msti 0: root_id 32768.0000.0000.0001, root_cost 0, update_flag 0x0

msti 1: root_id 32769.0000.0000.0002, root_cost 1, update_flag 0x0

Command

Purpose

Step 1

enable

Example:

Router> enable

Enables privileged EXEC mode.

Enter your password, if prompted.

Step 2

configure terminal

Example:

Router# configure terminal

Enters global configuration mode.

Step 3

vfi vfi-name manual

Example:

Router(config)# l2 vfi vfitest1 manual

Creates a Layer 2 Virtual Forwarding Instance (VFI) and
enters the Layer 2 VFI manual configuration submode.

Step 4

vpn id

vpn_id

Example:

Router(config-vfi)# vpn id 303

Sets or updates a VPN ID on a VPN routing and
forwarding (VRF) instance.

Step 5

bridge-domain

bridge_id

Example:

Router(config-vfi)# bridge-domain 100

Binds a service instance to a bridge domain instance.

Step 6

forward permit l2protocol all

Example:

Router(config-vfi)# forward permit l2protocol all

Defines the VPLS pseudowire that is used to transport
bridge protocol data unit (BPDU) information between
two network provider edge (N-PE) routers.

Step 7

neighbor

ip-address vc-id {encapsulation mpls

|pw-class pw-class-name}

Example:

Router(config-vfi)# neighbor 10.10.10.10 1

encapsulation mpls

Specifies the routers that should form a point-to-point
Layer 2 virtual forwarding interface (VFI) connection.
