EIGRP Routing Concepts and planning
· -- Why would you choose EIGRP
· -- EIGRP table and terminology
· -- Visiting the friendly EIGRP neighbor
· -- Visiting the no so friendly EIGRP metric calculation ( the K valuation)
EIGRP is the best protocol and why you would use it? It’s the fastest to converge, and the easiest to configure.
1.- Back Route : ( Fast Converge/ Dual) : Primary route and Backup Route ( Feasible Successor)
3.-Flexibility
4.-Unequal cost-load balancing.. No other protocol do tah..
5.-Combine the best of distance vector (very fast to converge like rip) and link state
A router running EIGRP runs 3 tables: neighbor, topology and routing table
· Neighbor Table: A list of all neighbor that it has directly connected
· Topology table: List the best router ( successor route) , and the second best route ( Feasible route) , a back up. It will automatically switch if primary fails.
· Routing table: Every router maintain it’s the best route, that router knows about
EIGRP Table and terminology
A)Feasible distance (FD)How far is four you to get to a specific route
Feasible Distance : The cost of fort R1 to get to 10.1.2.0/24 network is 110
B)Advertise Distance: ( AD) : How far is going to be to get to your neighbor
· Succesor: Primary
· Feasible Succesor: Backup
Active Route : Bad one.. stop, witing to be connected
Pasive route: good one
Visiting the no so friendly EIGRP metric calculation ( The K valuation)
MTU is NOT a part of the bandwidth calculation: it’s a maximum trasmition unit.. ( How big a packet can be send on a link).
It’s not a factor in the formula to calculate the best way of EIGRP to get to the network
