I am fairly sure that on a p-to-p link between 2 routers if I ping my local
interface on one of the routers the packets traverse the frame circuit to the
other router and then returns and this happens at L2. The other router will
return the frame because of its local mapping for the DLCI. I am trying to
test in the lab in order to prove it to Cisco TAC Engineer I am working with.
I have the following:
R1---------R2
both of them with a p-to-p subinterface using frame-relay interface-dlci
xxx..
I can see the counters increment slightly on R2's interface when I ping the
local interface on R1 from R1. However none of the debug commands I try shows
any output on R2. The TAC guy says the increase in traffic is from LMI or
something else. Anyone know of a way to see this traffic on R2? I have
increased the size of the pings and I see the load increase as a result and
the nimbers are really close to what I would expect to see. But, with 30
second intervals it is hard to prove.
Thanks
Rick
