A router is set up to redistribute routing updates from OSPF to RIP. What answer best describes issues the network administrator needs to be aware of?

A.
Split Horizon, Poison Reverse, Holddown

B.
Slow convergence, limited hop-count metric, lack of network mask information, periodic broadcasts

C.
None, OSPF is a link-state routing protocol which overcomes issues found in RIP.

D.
Difference in metrics (e.g. hops vs. cost), subnet mask allocation/addressing (e.g.
VLSM vs. fixed subnet mask length), routing
protocol summarization (e.g. network boundaries)
