multihoming-peer-gateways

Syntax

Note:

In releases prior to Junos OS Release 24.2R1, this statement was named interconnect-multihoming-peer-gateways. Starting in Junos OS Release 24.2R1, the Junos CLI automatically aliases the interconnect-multihoming-peer-gateways statement to this multihoming-peer-gateways statement. As of that release, you won't see the interconnect-multihoming-peer-gateways statement in the Junos CLI, and you should use this multihoming-peer-gateways statement instead.

The multihoming-peer-gateways statement supports multiple multihoming feature use cases, including the original function of the interconnect-multihoming-peer-gateways statement.

Hierarchy Level

Description

Specify Ethernet VPN (EVPN) provider edge (PE) multihoming peer devices.

EVPN PE devices are multihoming peers when they share an Ethernet segment (ES) for a multihomed customer edge (CE) device or attached host. Configure this statement on a PE device to statically identify its multihoming peer PE devices.

Use this statement with EVPN multihoming peer PE devices such as:

  • Data center interconnect (DCI) multihoming peer interconnect gateway (iGW) devices—When you configure this option, the iGW devices avoid loops during EVPN configuration changes and can handle control plane routing more simply, which helps optimize forwarding between the peer iGW devices.

    We require this statement on all peer multihoming iGW devices that use the interconnect statement to configure data center interconnect (DCI) and seamless stitching with EVPN Type 2 or Type 5 routes.

  • Enhanced optimized intersubnet multicast (OISM) multihoming peer leaf devices—When enhanced OISM leaf devices have static information about their multihoming peers, the multihoming peer leaf devices can avoid multicast traffic loss when their peer devices go up and down.

    We support this statement with OISM in enhanced OISM mode only.

Options

(multihoming-peer-gateway-IP-address | [multihoming-peer-gateway-IP-address …])—One or more multihoming peer PE device loopback IPv4 addresses. Specify a single address or list multiple peer device addresses within square brackets.

Required Privilege Level

routing—To view this statement in the configuration.

routing-control—To add this statement to the configuration.

Release Information

Statement introduced in Junos OS and Junos OS Evolved Release 22.2R1.
