Processing RIP Updates

Update

• R2 received this information on an interface that belongs to the same classful network (172.30.0.0) as that of the incoming 172.30.1.0 update.
• The IP address for which R2 received the "172.30.1.0 in 1 hops" message was on Serial 0/0/0 with an IP address of 172.30.2.2 and a subnet mask of 255.255.255.0 (/24).
• R2 uses its own subnet mask on this interface and applies it to this and all other 172.30.0.0 subnets that it receives on this interface - in this case, 172.30.1.0.
• The 172.30.1.0 /24 subnet was added to the routing table.
