DLSW and Tunnel Interfaces problem

[abekeris]

We have a pair of routers with tunnel interfaces and DLSW between them.

Some times the tunnel interface goes down thus loosing service trough DLSW.

Is there any problem reported between DLSW and this kind of tunel interfaces ?

Hi,

i assume you are using dlsw tcp peers.

In general dlsw does not know over what infrastucture the connection really runs. Dlsw gives data to tcp and tcp is responsible for doing the actual transmission.

I dont know of any problems with dlsw and tunnel interfaces in general.

Some more information might help to understand the problem.

What type of tunnel are you using? GRE?

What version of ios are you running?

Do you use additional encapsulation overhead like ipsec ect?

Does tcp on this router use path mtu discovery?

thanks...
