MPLS over a TE tunnel

[thedquoc]

Hi ,

I tried to configure MPLS over a TE tunnel by following this link : http://www.cisco.com/en/US/tech/tk436/tk428/technologies_tech_note09186a0080125b01.shtml#case1 .

The problem happened in this tunnel interface config :

----

!

interface Tunnel0

ip unnumbered Loopback0

no ip directed−broadcast

no ip route−cache distributed

tunnel destination 10.5.5.5

tunnel mode mpls traffic−eng

tunnel mpls traffic−eng autoroute announce

tunnel mpls traffic−eng path−option 10 dynamic

end

!

----

The int tunnel 0 is always in "Tunnel0 is up, line protocol is down" state .

My PE routers are 7304s(p-mz.122-27.SBC5)

Please advice !

Thanks & Regards

If you do a "sh mpls traffic-engineering tunnels tunnel 0", was is the info that is displayed? Please let me know.

Thanks.

Did you configure MPLS specific statements under your IGP (either ISIS or OSPF) as follow:

OSPF:

mpls traffic-eng router-id Loopback0

mpls traffic-eng area 0

ISIS:

mpls traffic-eng router-id Loopback0

mpls traffic-eng

Also did you configure all interfaces for mpls traffic engineering between the headend and the tailend using the following statements:

mpls traffic-eng tunnels

ip rsvp bandwidth

Hope this helps,
