Multihoming peer OISM leaf devices in an EVPN-VXLAN network running enhanced OISM

We can statically configure a multihoming peer leaf device to identify its peers in an Ethernet VPN-Virtual Extensible LAN (EVPN-VXLAN) network running enhanced optimized intersubnet multicast (OISM). EVPN-VXLAN provider edge (PE) leaf devices are multihoming peers when they share an Ethernet segment (ES) for a multihomed host. With enhanced OISM, if the leaf devices have static information about their multihoming peers, they can avoid multicast traffic loss when their peer devices go down and up again.

On each multihoming peer leaf device, to identify the device's multihoming peers, configure the multihoming-peer-gateways [peer-device-IPv4-address ... ] statement at the [edit protocols evpn] hierarchy level.

Specify a list of peer addresses within square brackets, or specify a single peer address without any brackets.
