Task 4.5.4 Tunnel Failover: Why have R4_BACKUP explicit-path option ?
Friends in task 4.5.4 solution you see that foll is configured
tunnel mpls traffic-eng path-option 1 explicit name R4
tunnel mpls traffic-eng path-option 2 explicit name R4_BACKUP
I was wondering, do I lose points for this task if chose path-option 2 to be dynamic ?
After all the only way for R2 to esatblish the tunnel after the link failure between R2-R5 is via the FR link.
Then why do an explicit path for the same ?
