All protocols can load-balance across _ equal cost links.
four
Which protocol can load-balance across six unequal-cost links?
EIGRP supports 6 unequal links.
RIPv2 and OSPF support four but need to be equal links.
What does RIPv2 use to prevent routing loops?
Split horizon rule,
Route poisoning and
Holddown timers
Which protocol uses wildcards in network statements?
OSPF
What is significance of OSPF process ID?
locally significant, identifies unique instance of OSPF database

How is OSPF Router ID determined?
Highest IP address of all loopback interfaces, secondly highest IP of al active interfaces
How is OSPF Designated Router determined?
