Ethernet VPN multihoming-Ethernet segment identifier per interface

Junos OS enables the Ethernet VPN (EVPN) multihoming feature to connect a customer site to two or more PE devices to provide redundant connectivity. A CE device can be multihomed to different PE devices or the same PE device. A redundant PE device can provide network service to the customer site as soon as a failure is detected. EVPN multihoming helps to maintain EVPN service and traffic forwarding to and from the multihomed site if one of the following types of network failure occurs:

• PE device to CE device link failure
• PE device failure
• MPLS-reachability failure between the local PE device and a remote PE device
