[j-nsp] GRE Keepalive problem

[Youssef Yosry]

Hi All,

 

I did create a GRE tunnel between to J4300 routers over ISP network, but I
did found that when the physical interface on one side went down the GRE
tunnel interface on the opposite side is still UP. So is there some kind of
keepalive over GRE so when missing these keepalive the GRE became down.

 

Please advice.

 

 

Best Regards,
