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.
NOTE: ACX Series routers do not support vpn-unequal-cost statement.
