hello

How is load balancing of labeled packets performed in Cisco IOS?

thanks

Hello Wang,

load balancing of labeled packets happens by using the external label value as a key to decide out what interface to send the packets

the decision is taken once all packets of the same flow follow the same rule/path

There was a thread some mounths ago about this.

see

Hope to help

Giuseppe

Giuseppe,

If the information directly after the label stack is IPv4, we actually use the IPv4 source and destination for load balancing purposes.

For other type of traffic, we generally use the internal label (service label) for load balancing purposes.
