Description
Enable protocol-independent load balancing for
Layer 3 VPNs. This allows the forwarding next hops for both the
active route and alternative paths to be used for load balancing.
For IPv6, you must configure the multipath statement at
both the [edit routing-instances routing-instance-name routing-options] hierarchy level and the [edit routing-instances routing-instance-name routing-options rib routing-table-name] hierarchy level.
Protocol-independent load balancing is applied to VPN routes
that are equal up to their router identifiers (router-id) with regard to route selection.
The options are explained separately.
ACX Series routers do not support vpn-unequal-cost statement.
