Mark MPLS-Enabled on Links Along Path
When tunnels are placed by the routing engine, it checks the protocol on the link to determine if it is mpls-enabled to allow placement of the tunnel. One method of setting a link to be mpls-enabled is through the Modify Tunnel window. Switch to Modify mode and select Modify > Elements > Tunnels to open the Modify Tunnel window. Choose a tunnel, right-click, and select “Mark MPLS-enabled on links along path.” This will set all links as mpls-enabled on the first Configured Route. If the first Configured Route is dynamic, then no links will be set as mpls-enabled.
