L2VPN PW Class

Configure L2VPN Pseudowire Class templates for MPLS-based Layer 2 VPN services on IOS-XR devices. Pseudowire classes define encapsulation methods, transport modes, and load balancing parameters that can be applied to pseudowire configurations for consistent behavior across multiple pseudowires.

Sample Configuration:

The following configuration describes how to set up L2VPN pseudowire class parameters on a Cisco IOS-XR device.

l2vpn
 pw-class <name>
  encapsulation mpls
   transport-mode ethernet
   transport-mode vlan
   transport-mode passthrough
   load-balancing
    pw-label
    flow-label both
     static
    flow-label code 17
     disable
