Hi All,

I have two router connected back to back. I just started configuring rip on
them. I got a lil confused by seeing the route table.
I want to know how the subnet masks are being shown when i am using ver1 of
rip. *[192.168.20.48/32 ]*
I have been practicing a lil while now & my head is aching, am not able to
reason out. It will be nice if somebody can help me out here.
