RE: LDP/TDP

R5 has defaulted to TDP due to you not specifying LDP from what I can see.

You can use Mpls ldp neighbor xxxx password to authenticate your LDP/TDP
sessions

could you give show mpls ldp neighbor outputs on both routers?

If you have LDP on the PE router, and have specified TDP on the CE then I
don't think the MPLS LDP/TDP relationship is up.

They both need to be the same, or you can run mpls label protocol both.

But if the relationship is up then the command mpls ldp neighbor xxxx password
will work

Sorry I did not give enough info...

7200 PE router is running LDP and on the interface connected to the CE 2600
TDP router i have
"mpls label protocol tdp"

my mpls LDP/TDP neighbor is up now i need to runn authentication between these
2 routers. can thise be done? or do i now need to reconfigure my PE router to
run TDP.

Hi Shaughn,

In that case, TDP runs on both.
Then I don't think 'mpls ldp nei x.x.x.x password' is applicable to TDP? It is
only for LDP. Isn't it?

I guess if want to go for authentication, you need to use LDP.

Ah, sorry. Didn't read the e-mail correctly

If you are trying to run TDP and LDP it wont work unless you have the keyword
"both" enabled on the interfaces.

If you have done that then my previous e-mail is correct, you can run mpls ldp
neighbor xxxx password

Hi,

I think, you need to use same label distribution protocol between neighbors.
Isn't it?
I am not sure, how you can run TDP and LDP between neighbors.

You may configure 'mpls label protocol both', but it just supports both
protocols.

But you can not run LDP and TDP between neighbors.

Thanks,
Srinivas
