MPLS-TE tunnels not established

Thu Dec 21, 2017 1:07 pm

Hi all,

I want to build a mpls te tunnel between our two edges. these two edges are connected to our core router. All 3 routers are MPLS enabled and running. OSPF running as IGP. I have attached the diagram for your reference. I have followed this mikrotik documetation ( https://wiki.mikrotik.com/wiki/Manual:Simple_TE#) and my tunnel is not established. Path state is on hold. Is there any configurations I need to done in cisco router also ? What could cause tunnels to not come up ?

Thanks.

TE tunnel is a simplex connection. You need to run in at the other side too. From A to B and from B to A. This is one tunnel. And it's not realy a tunnel. It's not encapsulating anything, it's just gather info about available resources on net.

You need to run RSVP protocol on cisco interfaces too, otherwise resource reservation along the path will not be possible.
Also depending on what Te tunnel path type you are using, if CSPF is used then you also need to configure OSPF on Cisco to work with CSPF

Thank you very much ! After enable RSVP in cisco routers it works.

Hi,

Sorry to hijack and revive this thread but how did you enable RSVP on the cisco interfaces?
I have something like this on my setup and am facing the problem you stated initially, only difference is that i have two cisco routers as core LSRs.

Hi there,

you need to configure rsvp configurations under the interface of core LSRs

Thanks.
