Module 2 – Layer 2 EVPN 

• Explain the use case for L2 EVPN

• Describe the L2 EVPN operations 

• Configure a MAC-VRF for L2 EVPN with SR Linux CLI

• Verify the details of L2-related EVPN Routes (MAC and IMET) 

• Review the L2 EVPN MAC protection, MAC mobility and MAC duplication monitoring procedures

• Explain the need for proxy-ARP in a L2 EVPN, and how to apply proxy-ARP to IP duplication detection (IP anti-spoofing)

• Configure Proxy-ARP in a L2 EVPN

• Hands-on Labs:
