Hi,

You are getting following error:
   Path Option 10:

      Last Error: PCALC:: No path to destination, 0000.0000.0008.00

You can check why you are getting this.
Can you give following show outputs from both R8 and R9

show mpls traffic-eng topology brief

show mpls traffic-eng tunnels topology path destination <tunnel dest addr>
show mpls traffic-eng tunnels topology path destination <tunnel dest addr>
bandwidth
show mpls traffic-eng tunnels topology path destination <tunnel dest addr>
priority

show mpls traffic-eng tunnels topology path tunnel89
show mpls traffic-eng tunnels topology path tunnel89 bandwidth
show mpls traffic-eng tunnels topology path tunnel89 priority

Thanks,
Srinivas

Hello Experts,

   I have been troubleshooting this for like 2 hours now and just cannot see

what is wrong. I have read through the IPExpert article and tried the auto bw

commands and it made no difference. Also, I am able to ping perfectly fine. I

am trying to go R8-R2-R7-R9 and reverse path back, but my tunnel on R8 and R9

will not come online. I have also lowered the bandwidth on the RSVP as well
as

on the tunnel and this didnt help.

Here is the config:

R2

mpls traffic-eng tunn

router isis

mpls traffic-eng level-1

mpls traffic-eng rou lo0

int e0/0.28

mpls traffic-eng tunn

ip rsvp band 5000

int e0/0.27

mpls traffic-eng tunn

ip rsvp band 5000

r7

mpls traffic-eng tunn

router isis

mpls traffic-eng rout lo0

mpls traffic-eng level-1

int f1/0.27

mpls traffic-eng tunn

ip rsvp band 5000

int f1/0.79

mpls traffic-eng tunn

ip rsvp band 5000

r8

mpls traffic-eng tunn

router isis

mpls traffic-eng rou lo0

mpls traffic-eng level-1

int f1/0.28

mpls traffic-eng tunn

ip rsvp band 5000

int tunn 89

ip unn lo0

tunn so lo0

tunn dest 32.32.0.9

tunn mode mpls traffic-eng

tunn mpls traffic-eng prio 7 7

tunn mpls traffic-eng band 2000

tunn mpls traffic-eng path-opt 10 dynamic

tunn mpls traffic-eng autoroute announce

r9

mpls traffic-eng tunn

router isis

metric-sty wide

mpls traffic-eng rou lo0

mpls traffic-eng level-1

int f1/0.79

mpls traffic-eng tunn

ip rsvp band 5000

int tunn 98

ip unn lo0

tunn so lo0

tunn dest 32.32.0.8

tunn mode mpls traffic-eng

tunn mpls traffic-eng prio 7 7

tunn mpls traffic-eng band 2000

tunn mpls traffic-eng path-opt 10 dynamic

tunn mpls traffic-eng autoroute announce

If I do a sh mpls traff tunn I get

R9

Rack1R9(config-if)#do sh mpls traffi tunn

TIA for any help.
