Routing Protocol
Router learn indirectly connected network with RP.

-Routing Information Protocol, Distance Vector Routing
RIP (Hop Count MAX 15)
Periodic Update Routing Table, 30s
-IGRP , 90s

-Open Shortest Path First, Link State Advertisement
OSPF (Path Cost, MAX hop 255), Fast RP
3 Tables (Neigbours, Topology, Routing)
-Interior Gateway Routing Protocol, Balance Hybrid

-EIGRP
(Only Update when path change), Fast RP
Primary Route, Keep Backup Route
(K Value->Bandwidth,Delay,Loading,MaxTransferUnit,Reliability)

*Prior the lowest Administrative Distance (AD) of Routing Protocol
EIGRP-90AD
RIP-120AD
OSPF-110AD

IP Route (Static/Dynamic)
-show ip route

Save configuration
1. copy running-config startup-config
2. write memory

TIPS:
Add prefix {no} onto snytax command to remove settings.
