Short answer:
RIPv1 supports host routes.
Long answer:
RFC 1058

<Quote>
The RIP protocol makes no formal distinction between networks and hosts.
It simply describes exchange of information about destinations, which
may be either networks or hosts.

Good luck on the lab ;-)

Subject: RIP classful or not
Hello, Group.
I found something interesting (and troubling for me)with regards to RIP.
My
understanding of RIP v1 is that it will not pass routes that do not
match
the subnet mask of the outgoing interface. I thought this was true for
both
RIP routes and routes redustributed into RIP. I saw a scenario where a
/32
route was being sent out of a /24 interface and appearing in the routing
table of the router on the other end. This /32 route was being
redistributed into RIP from OSPF. My question is does the rule of
routes
having to match the mask on the outgoing interface not apply to routes
redistributed into RIP?
The scenario used a prefix-list to stop /32 routes from being
Redistributed
from OSPF into the RIP domain.
ip prefix-list 1 seq 10 permit 172.31.0.0/16 le 31
Without this line, the RIP domain would see these /32 routes.
Is this normal?? I'm 2 days away, fellas. I gotta clear this up soon.
Thanks,
Danny
