Q: What do the characters C L S * R O and D represent in the routing table
A: C: directly connected networks
L: local routes within connected networks
S: static routes
*: default route
R: RIP
O: OSPF
D: EIGRP

Q: What are the two tpes of routing protocols
A: Distance-vector routing protocol: Routers communicate with neighbors about topology changes periodically -EIGRP RIPv2
Link-state routing protocol: Router informs all nodes of topology changes - OSPF and IS-IS
