Re: MPLS Traffic-Engineering Dynamic Tunnel

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
