Reduced routing table size

Automatic summarization at classful boundaries
Next hop router interface
Unicast host address
Layer 2 address
Host B has a defective Ethernet card.
The default gateway on Host B is not correctly set.
There is a Layer 2 problem between R2 and Host B.
R2 does not have routes back to networks connected to R1.
Because RIPv2 does not support VLSM, the subnet masks will not be allowed.
The subnets will not have enough host addresses for the given network requirements.
The subnets overlap and will be rejected by the router.
The router will support the addressing scheme.
The network for a default route
A network that contains both private and public addresses
A set of discontiguous networks that are controlled by an ISP
A summarization of serveral IP classful networks into one IP address range
Here's an interesting quiz for you.
