[c-nsp] mpls/ip load balancing

Best is  to check "show ip cef internal" to see if the packets are load balanced. 

Afaik, IOS does not load balance between labelled and unlabelled paths.


(Think about sending AToM or MPLS VPN traffic out towards an unlabelled path.)

Hi - does anyone know how load balancing by default works over two paths,
one using MPLS and the other one IP. I have the same route advertisement
received over two different interfaces. On one interface LDP is enabled (and
of course OSPF), the other interface is only OSPF enabled. Traffic
is definitely load balanced across the two interfaces, but I was wondering
what fields the hashing is based on?
Thanks,
Marlon
