EIGRP (Associate to Professional level)

Hello Pradyumna

If there are two routes to a particular destination and their cost is equal, you will have two successors, and both routes will be placed in the routing table. Equal cost load balancing will take place between those two routes. In order to make one of the two a FS, you must adjust the cost by adjusting one of the K values to make one route preferable. Take a look at this lesson for more information:

This is the default behaviour of EIGRP and it is based on rigorous testing to find the best parameters that work for most topologies.

The unit is “tens of microseconds”. So a value of 40 is 400 microseconds. More info can be found at this lesson:

This one may be an error in the output. I will let Rene know and get back to you…

You can find out about the Null0 exit interface at the following lesson:

Here’s another example of how it is used in BGP:

The ip default-network command essentially tells the router to route all traffic that doesn’t match any other routing table entry, as if it was destined for In other words, a packet with a destination address of (which is not in the routing table) will be routed as if it was an address in the network.

I hope this has been helpful!
