3 Way how router learn routes
- Directly connected
- Static Routes
- Dynamic routes
Types of IGP
- Distance Vector [routing with rumor]
- Link State Protocol
send their entire routing table to directly connected neighbors
Distance Vector [RIP]
send information about directly connected links to all the routers in the network.
Link-State Protocol [OSPF]
has some characteristics of a link state routing protocol, and some characteristics of a distance vector routing protocol.
Hybrid Protocol [EIGRP]
Algorithm use by EIGRP
diffusing update algorithm (DUAL)
EIGRP support how many hops
255
EIGRP - The route with the lowest path metric to reach a destination.
successor route
EIGRP - The first next-hop router for the successor route.
successor
EIGRP - The metric value for the lowest-metric path to reach a destination.
Feasible distance (FD)
EIGRP - The distance reported by a router to reach a prefix.
Reported distance (RD)
EIGRP - A route that satisfies the feasibility condition and is maintained as a backup
route.
Feasible successor
