Hi:
Does any one know of some simple t-shooting steps for MPLS TE tunnels.
I have a very simple TE config from one router to another and back but 1
Tunnel is up/down.
I found out that everytime I configure the tunnel mode mpls traffic-eng cmd,
the tunnel goes up/down.
But the same cmds. on the other tunnel keeps that tunnel up/up in that
router.
I checked the status and keep seeing this msg:
Last Error: RSVP:: Could not add RSVP Path: Operation failed
I debug'ed rsvp and te tunnels and get this msg:
Mar 5 23:59:56.768: RSVP 131.1.6.6_34->131.1.4.4_1[131.1.6.6]: PATH: Error
upda
ting received ERO (error code 2)
Now the configs are the same on both the routers: to and from.
r6#sh int tu1
Tunnel1 is up, line protocol is down
Hardware is Tunnel
r6#sh run int tu1
Building configuration...
Current configuration : 366 bytes
!
interface Tunnel1
ip unnumbered Loopback0
mpls traffic-eng tunnels
tunnel destination 131.1.4.4
tunnel mode mpls traffic-eng
tunnel mpls traffic-eng autoroute announce
tunnel mpls traffic-eng priority 7 7
tunnel mpls traffic-eng bandwidth 1000
tunnel mpls traffic-eng path-option 1 explicit name R6->R4
tunnel mpls traffic-eng path-option 2 dynamic
end
r6#
Thx.
