Hi All,
Do anybody know why the encapsulation always failed on every type of
interfaces on my 7206 router?
I have replaced the I/O and the encapsulation is still FAILED!!!
Below is the "debug ip packet" of the interface e1/0 pinging the
default-gateway with the encapsulation FAILED and pinging itself
successfully:
routerB#debug ip packet
IP packet debugging is on
routerB#ping 192.168.0.1
Type escape sequence to abort.

I am suspecting the version of the IOS image have something to do with it but
not sure. I purchase this router without IOS image and running a 12.2.10a
image.
Thanks in advance for all your help!!!!
