P router load-balance

[xzffly]

In one based-ldp's mpls domain,how p router do with load balance ?

thanks!

The P router uses the ipv4 (or ipv6) info contained in the MPLS packet to do per-flow load-balancing. If no ipv4 info is present it uses the inner most label to perform the hashing algorithm.

Hope this helps,
