Yes. It is the nature of hdlc as it is a point to point protocol . When you have 2 routers back to back with hdlc serial you will see the same behavior.

Subject: Router-ping
I have been having an issue I am trying to understand. I have a router with
the following setup.
(DVB Modem)--------------------------Rx-(gig0/0) Router (S0/0)
tx-----------------(SCPC- Modem)
Funny enough, I can't explain why when logged into the router, I try to ping
the serial interface IP address and I do not get a reply. (it timesout). I
do a traceroute to the serial interface IP address and it takes me out to
the ISP side (router default gateway) , then back into the router through
the Rx interface (gig0/0). I actually have an access-list denying incoming
traffic on the Serial interface. It is not a frame-relay link, but using
HDLC encapsulation.
Any ideas....?
