RSVP-TE tunnel does not establish

[quad99]

Hi
I am doing a simple lab and at the very beginning I have a problem .Well it does not set up the tunnel ,I have checked the configuration many times with the official cisco materials and the configuration seems correct. Anyone can help ?

Below i am uploading my topology along with the configuration.

in
ip explicit-path name <X>

Use LO of P1 and P2 dont use direct connect IP 

try above and check Oper of Tunnel 

MHM

[quad99]

I've done on PE1:

ip explicit-path name PE1-PE2 enable
next-address 2.2.2.2
next-address 4.4.4.4
!

and on PE2 :

ip explicit-path name PE2-PE1 enable
next-address 2.2.2.2
next-address 1.1.1.1
!

and there is no change..

I dont see topolgy' but I think P1 and P2 is between two PE and last your config you use only one LO? Last LO for tunnel destination it not count.

I have inserted a png of the topology above , but I am uploading it in an attachment just in case.

[MHM Cisco World]

show mpls ldp neig <<- share this for all router 
thanks 

MHM

[quad99]

I have not configured LDP , so the command does not show anything. Here it's all about rsvp signaling.

[MHM Cisco World]

show mpls traff tunnel detail <<- in both PE1/2 share this 
show ip route <<- in PE1/2 check if P1/P2 LO is known or not 

MHM

[quad99]

There's no command or any similiar one to "show mpls traff tunnel detail"

Loopbacks are known to both PE routers

[MHM Cisco World]

Show mpls traffic-engineer tunnels details <<-

Hi @quad99 ,

It appears that "mpls traffic-eng tunnels" might be missing from P1 in global mode. That is probably why the output says "unknown address 2.2.2.2".

Can you provide the output for the following command from PE1:

sh mpls traffic-eng topology brief

Regards,

[quad99]

Hi @quad99 ,

The mpls traffic engineering database is missing the information for P1 (2.2.2.2) and P2 (3.3.3.3). Please make sure you enter "mpls traffic-eng tunnels"  in global mode and "mpls traffic-eng router-id Loopback0" under router ospf  on these two routers. 

Regards,
