Re: Last Error: PCALC:: No addresses to connect 10.127.1.70 to 1

Hello, You must have a global command mpls label protocol ldp, You must have a mpls ldp neighbor relation ship between the routers which come in to picture when you are trying to do MPLS Traffic Engineering.

Your IGP Protocol ISIS or OSPF must be ready for MPLS Traffic engineering.

then after as per your configuration there must be Explicit or Dynamic Path.

There must be a tunnel in which you call your path-option.

Later there should be a static route for the intended destination via the tunnel which you have your path option set.

Please rate the helpful answers/discussions.

Make sure you share more information about the configuration of the involved parties in order to get a faster and precise response.

Some general recommendations:

- ISIS TE extension requires wide metrics;

- If ISIS is being used for IPv4 and IPv6, and you have a mix of IOS and IOS-XR in your environment, change the ISIS configuration on IOS to operate in multi-topology mode.

- Check if mpls-te and rsvp-te is enabled at all interfaces in the path between head end and tail end.

I have configured MPLS tunnel

I have configured MPLS tunnel in GNS3 but tunnels is unable to come up.

Both head and tail routers are pingable through OSPF with loopback interfaces.

Can anyone tell me where I am committing mistake?

can u please share the tunnel

can u please share the tunnel config along with protocol config for TE, note that your LSP should be continuos.

Hello PlaWAnSai,

you haven't provided enough information to be helped effectively.

The most important configuration object to see is tunnel 3500 that should be defined on node named b2.

If you have used an explicit path for the MPLS TE tunnel tu3500 you may need to list both the endpoints of a TE link instead of simply listing

10.127.1.70 10.127.1.26 in the path definition you may need something like the following:

10.127.1.69 10.127.1.70 10.127.1.25 10.127.1.26

At least so it was with explicit paths some years ago if I remember correctly at least on LAN broadcast interfaces

You don't need to enable LDP.

Hope to help

hi, this is a very old thread

hi,

 

this is a very old thread but I would like to add something.

'Last ErrorPCALC:: Destination IP address, xx.xx.xx.xx, not found ' this means there is missing configuration in the TE tunnel. Please verify every router to configure tunnel into IGP protocol. Somewhere TE tunnel was not configure into the IGP protocol.

e.g (in-case of OSPF)

router ospf 1
 mpls traffic-eng router-id Loopback0
 mpls traffic-eng area 0
