EVPN with IRB Model Use case

Overview

This lab covers a L3VPN based on EVPN control-plane:

• Trunk link between s1-ce03 and s1-pe03 to carry vlan 1103
• Ethernet Segment to dual attached s1-ce01 to both s1-pe01 and s1-pe02 to carry vlan 1101 on trunk interface.
• Ethernet Segment is based on A/A model.
