GigabitEthernet3/1/2 turns into UP state
# Perform the display interface tunnel command on Router A to identify the state of the primary LSP.
You can find that the tunnel interface is up.
# About 5 seconds later, perform the display mpls lsp verbose command on Router B. You can find
that Tunnel5 is still bound with interface GigabitEthernet 3/1/2 and is unused.

Network requirements
Router A, Router B, Router C, and Router D are running IS-IS and all of them are Level-2 routers.
Use RSVP-TE to create a TE tunnel from Router A to Router D. Traffic of the tunnel belongs to CT 2, and the
tunnel needs a bandwidth of 4000 kbps.
For each link that the tunnel traverses, the maximum bandwidth is 10000 kbps, the maximum reservable
bandwidth is 10000 kbps, and BC 1, BC 2, and BC 3 are 8000 kbps, 5000 kbps, and 3000 kbps
respectively.
