You should able to ping the interface that used "ip unnumbered" cuz it use
Ethernet 0 IP address.
I tried to ping my PC to RO router. I should able to ping RO ip cuz my RO
Ethernet0 is xxx.xxx.96.65. The reason I used "ip unnumbered" to save my ip
address and that usually for DDR. Let see, there are 16 Async interfaces
and 16 dialer interfaces then I will loose 32 IPs just for that?
