Pseudowire (VPWS) Use case

Overview

This lab covers a VPWS Pseudowire based on BGP control-plane:

  • Ethernet6 is a UNI interface towards s1-ce03 on s1-pe03
  • Ethernet6 is a UNI interface towards s1-ce04 on s1-pe04
  • Vlan 1401 (10.4.1.0/24) is conefigured on ce devices using VPWS vrf.

Technical details

Connectivity

CE node CE interface IP address IP address PE interface PE node
s1-ce03 Vlan1401 / Ethernet3 10.4.1.13/24 N/A Ethernet6 s1-pe03
s1-ce04 Vlan1401 / Ethernet3 10.4.1.14/24 N/A Ethernet6 s1-pe04
