Dear Team,
We have made etherchannel between Cisco WS-C2950T-24 L2 & Cisco 7204VXR (NPE400) router for load balancing purpose.
But the traffic from L2 switch to router is just being forwarded on single port & other port is idle while router is properly load balancing on both the ports.
Below is the configuration for both the switch & router.
Switch Configuration ->
!
interface Port-channel2

We have tried changing load-balance algorithm on Switch but result is same. Can somebody please help for load balance the traffic from L2 to Router?
Thanks in advance.
