BGP multipath support

In general, BGP selects a single best path to a given destination. BGP multipath support allows multiple paths to a given destination. Having multiple paths to the same destination enables the traffic load to be shared across the multiple paths, and makes use of network resources that might normally be used only as backup.

The BGP multipath feature does not affect the BGP path selection process. Instead, the best path as well as the additional multipaths are all added to the routing table.

For more information on configuring BGP multipath support, see protocols bgp <asn> parameters maximum-paths ebgp <max-paths> and protocols protocols bgp <asn> parameters maximum-paths ibgp <max-paths>.
