David ,
1) 192.168.1.0 /24 and 192.168.1.0/16 are not the same networks.The latter
is net 192.168.0.0 /16.
2) Even if you include 192.168.0.0 /24 in the rip routing process a "debug
ip rip" will show that rip makes no effort to advertise the net
(192.168.0.0). My clumsy explanation for this behaviour is rip being the
"Classy" protocol it is ignores interfaces configured with a supernetted
mask ( class B in this case ). ????

Subject: rip problem
i thought i was going to do an easy excercise and
knock out RIP v1,v2.
it worked perfectly when i used these addresses.
192.168.1.1/24 --rtr1 <-> rtr2-- 192.168.1.2/24
router rip
network 192.168.1.0
but when i change the subnet mask to /16
they don't exchange routes.
debug ip rip -- shows no packets going out of or into either router.
sho ip proto -- shows the correct network and interfaces as active.
i left all other commands to the default for 12.0 ios.
ip classless
ip rip send v1 receive v1 v2
ip subnet-zero
etc.
Anybody have any ideas what is going on.
thanks,
David
