EVPN IRB
Ethernet VPN (EVPN) provides an extensible and flexible multi-homing VPN solution for Layer 2 connectivity
among hosts over an MPLS core/IP network. EVPN Integrated Routing and Bridging (IRB) feature enables
Layer 3 forwarding among hosts across different IP subnets, while maintaining the multi-homing capabilities
of EVPN. Also, EVPN IRB feature enables EVPN hosts or subnets to communicate with IP VPNs.
