We have a serial interface in a 7609 with firmware c7600s72033-adventerprisek9-mz.122-33.SRB5.bin that we are having a problem with a interface in a multilink. We can get the interface to come up with PPP no problem. But when we add multilink to the interface of a multilink that is up it will take the protocol down. When we shut down the multilink interface the serial will come back up but when we turn the multlink interface back up it will take the serial protocol down. This is the debug output but I can't find anything on it.

115899: Aug 7 10:59:54.125 CST: Se7/1/0/13:0 MLP: Link not added to bundle all
Any ideas?
Solved! Go to Solution.

I don't think this will work without two or more interfaces. Let me test and I'll get back with you.

You should check with your provider to make sure they provisioned your circuit for multilink. It has to be configured on their side as well.
Also, I noticed this line:
115898: Aug 7 10:59:54.125 CST: Se7/1/0/13:0 MLP: Bundle PVI in different multilink group
Are you adding to the right multilink group?

Yes this is the only interface in the multlink. It is configured as multilink on either end as I have access to both devices.
08-07-2009 08:22 AM
Why are you doing multilink if you only have one interface in the group?
08-07-2009 08:23 AM
Well there is two serials we are going to put in the multilink but we can't get them to come up so for right now the other serial is for access to the far end device.

Basically I am trying to find out what bundle PVI in different multilink group is coming up for.
08-07-2009 08:26 AM
Can you post the multilink interface section, and the serial interface sections that you're trying to add to the bundle?
08-07-2009 08:29 AM
Sure
interface Serial7/1/0/13:0
no ip address
encapsulation ppp
no fair-queue
ppp multilink
multilink-group 130
end
interface Multilink130
ip address 10.45.x.xx 255.255.255.252
ppp multilink
multilink-group 130
service-policy output voip-trust
end
xxxxxxx#show ppp multilink interface multilink 130
Multilink130 (inactive)
Member links: 1
Se7/1/0/13:0 (inactive)
Let me know if you can think of anything else.

I have tested this before with just one and it works just fine.

We found the solution. What happened was there was to CE or far end routers that had the same router name. That is why it said bundle PVI in different multilink group as we had to CE (Far end) routers with the same hostname (PVI).
