Hi,
I am trying to configure MPLS Tunnels.
I am not able to get the tunnels up. I have included the configs.
The sh ip route deal and the sh mpls traffic-eng interfaces detail all
outputs for all the 3 routers.
The network is also included in the text document.
Could anyone help me out by checking out the above configuration on MPLS.
Network Scenario: R4 (3620)-- R6 (3640) -- R7 (3660)
Aim: To get a LSP tunnel between R4 and R7
