EIGRP PART3

EIGRP K VALUES/Metrics:

By default EIGRP only uses 

K1= Bandwidth (Default) least bandwidth of all outgoing interfaces on the route to the destination network.
K2= Load

K3= Delay(Default) the sum of the delays configured on the interfaces, on the route to the destination network, in tens of microseconds.
K4= Reliabitly
K5=  MTU

Verify K values in use:

 EIGRP NEIGHBORSHIP FORMATION:

You can define static neighbor ships or dynamic ones. Under the router eigrp process you will need to define the static neighbor.

router eigrp 10
neighbor 192.168.1.2 fastEthernet 0/0


Verify static neighbor: Note the difference how shows you the static neighbor and the other does not.

The caveat with this is that you can not form dynamic neighborships once you specify a static neighbor via that interface. EIGRP disables all multicast messaging via that interface. You also still need to specify the network command for that specific interface.
