Release Information
Statement introduced before Junos OS Release 7.4.
Statement introduced in Junos OS Release 9.0 for EX Series switches.
Statement introduced in Junos OS Release 11.3 for the QFX Series.
Description
Allow load sharing among multiple EBGP paths and multiple IBGP paths. A path is considered a BGP equal-cost path (and will be used for forwarding) if a tie-break is performed. The tie-break is performed after the BGP route path selection step that chooses the next-hop path that is resolved through the IGP route with the lowest metric. All paths with the same neighboring AS, learned by a multipath-enabled BGP neighbor, are considered.
Options
multiple-as—Disable the default check requiring that paths accepted by BGP multipath must have the same neighboring AS.
vpn-unequal-cost equal-external-internal—Enable load-balancing in a Layer 3 VPN with unequal cost paths.
Required Privilege Level
routing—To view this statement in the configuration.
routing-control—To add this statement to the configuration.
