Protocol-independent load balancing for Layer 3 VPNs allows the forwarding next hops of both the active route and alternative paths to be used for load balancing. Protocol-independent load balancing works in conjunction with Layer 3 VPNs. It supports the load balancing of VPN routes independently of the assigned route distinguisher. When protocol-independent load balancing is enabled, both routes to other PE routers and routes to directly connected CE routers are load-balanced.
When load-balancing information is created for a given route, the active path is marked as Routing Use Only in the output of the show route table command.
The following sections describe how to configure protocol-independent load balancing and how this configuration can affect routing policies:
