Re: OSPF on 32 bit dialer interface

man sh ip route on the two devices u will found u will fing that the router
learns the remote ip address as /32 ? but this is not happening in all
cases some times it IOS bug try to use ur config with asnced enteripse
services IOS and i recommend try it in 7200 IOS i verified it many many
times and it works with the 7200 isod fine when i use 3640 i found it
learning the route to the remote neighbour as /32

while configuring this piece dubug ip ospf adj
and see the terminal it saying to u we recived a packet from another subnet
thats why it not coming up

in another case what if its rip the use no valaidate source in the
interface i think { refer to the DoC-CD} for right syntax.

its a bug and no worries

thanks,
