HDLC Keepalive

[pccthailand]

Hi

I checked link point-to-point HDLC between router A and router B, i saw Line protocol on router B down but on router A is normally then i debug serial interface command on both router to see keepalive messages . I found some question about output keepalive message on router A that is:

Mar 22 2006 Serial0/0: HDLC myseq 6550, mineseen 774091*,yourseen 86413, line up

Mar 22 2006 Serial0/0: HDLC myseq 6551, mineseen 774091*,yourseen 86414, line up

From the output keepalive on router A , why router A not detect the link down ?

Thanks

It could be possible that you have one-way traffic where traffic from Router B is getting to Router A but traffic from router A is not getting to router B...

You might want to check your cabling

Hope that helps - pls rate the post if it does.
