Hi Team,
i have some concerns regarding cisco's implementation of traffic engineering Tunnels.
Tunnel configuration : -
interface Tunnel1
description FROM-ROUTER-TO-R4
ip unnumbered Loopback0
no ip directed-broadcast
tunnel destination x.x.x.x
tunnel mode mpls traffic-eng
tunnel mpls traffic-eng priority 5 5
tunnel mpls traffic-eng bandwidth 10000
tunnel mpls traffic-eng path-option 5 explicit name PATH1
tunnel mpls traffic-eng path-option 10 explicit name PATH2
tunnel mpls traffic-eng path-option 15 explicit name PATH3
tunnel mpls traffic-eng path-option 20 dynamic
Please help to answer below questions:-
1. Tunnel is configured with four paths , please confirm whether all these path are hot-standby (Pre signaled) or cold-standby ?
2. What is the revertive time of traffic engineering ? ( in case path option 5 went down , tunnel will switch to path option 10 then if path option 5 came up, after how long tunnel will switch back to path-option 5 ?)
3. what is the use of "protected by" keyword in configuration ?
Thanks in Advance
SK
