Turn off keep alive on gre tunnel

Hi

I am trying to setup a gre tunnel, problem is it doesn’t seem to be working.
I think what the problem is, is I have keep alive turned on, I can see icmp to the tunnel remote address, but they don’t have icmp turn on ..

So even though I can see GRE packets coming from them, I don’t see the interface as being running.

how do I turn off keepalive, if thats whats doing it ?

Typical …

after posting this I realised unset <> keepalive !!!

added in case any one else searches for it
