Hi Kumar,

 

The configs you supplied have an IP addressing error.

 

On VLAN23 in the 9706 you have an IP address of 10.200.144.41 but on the Branch 2 5700 you have an IP address of 10.200.114.42. I think you have made an error on the 3rd octet, both should be either 114 or 144!

 

Regards Nigel

Thanks

Hi Kumar,

 

I tested your configs on eNSP as I do not have access to the necessary hardware, however with the addresses corrected for me it brought up both ISIS and LDP sessions so I'm not quite sure what else to suggest other than to confirm L2 and L3 connectivity first.

Sorry Kumar I did not bother saving the topo file, however it was very straightforward:

 

I used 3 S5700, 1 was acting as the core S9700 and I just directly connected them togethr and basically pasted your configs into them.

 

Regards Nigel
