TE lab testing flushing out how TE works, configured a primary and backup tunnel between PEs, both directions. Primary is dynamic and backup is explicit, initially priorities were the same, I then choose to make one tunnel preferred over the other adjusting the priorities, I choose the tunnel that was backup to become primary to watch the traffic shift. (primary path was P1-P2-P3, backup path P1-P3). However, the traffic did not shift, a manual shut on a P3-P2 interface made the traffic shift, reintroduction kept the traffic on P1-P3, then a "mpls traffic reoptimize" moved the traffic back to P1-P2-P3. Obviously the preferred MPLS tunnel is still P1-P2-P3 even though I configured "tunnel mpls traffic-eng priority 1 1" on P1-P3 and "tunnel mpls traffic-eng priority 7 7" on P1-P2-P3. What am I missing here? My setup: CE-----PE-----P1----------P3-------PE----CE \ / \ / P2 Mike
