Setting Unequal Load Balancing Parameters
The first step you must take to configure unequal load balancing requires that you set the parameters on each
specific interface. The default load share for tunnels with no explicit configuration is the configured bandwidth.
Equal load-sharing occurs if there is no configured bandwidth.Note
SUMMARY STEPS
1.
configure
2.
interface tunnel-te tunnel-id
3.
load-share value

DETAILED STEPS
PurposeCommand or Action
Enters global configuration mode.configure
Example:
RP/0/RP0/CPU0:router# configure
Step 1
Configures an MPLS-TE tunnel interface configuration mode and
enables traffic engineering on a particular interface on the originating
node.
interface tunnel-te tunnel-id
Example:
RP/0/RP0/CPU0:router(config)# interface
Step 2
Only tunnel-te interfaces are
permitted.
