I just took over a LAN/WAN structure and this is
something that I've never seen before.
When pinging across these two subnets, I'm getting
an extra IP address for the main router:
Main Office: (c3620)
Serial1/1: 10.0.5.2 <<---PPP to 10.0.5.1
Serial0: 10.0.5.1 <----PPP to 10.0.5.2
Starting in the main office's subnet, I'm pinging:
10.0.5.3 <---where is this coming from?!?!??
However, when doing a tracroute to an IP in the
10.0.6.0, the 10.0.5.3 IP does not show up.
If I telnet to this address (10.0.5.3), I get the
logon prompt for the main router.
Why is this happening?
