Re: a simple and strange 's router ping issue.

The reason they can ping each other is that, by default, PPP will exchange info about the IP address used by each side. This IP address will then be installed as a host router. If you issue the 'sh ip to' command, you will see that each router has a /32 route to the other router's IP address.
