EIGRP $$ Passive Interface

After you complete each step, put a $$ or $$x$$ in the completed box

Quick Reminder: Passive interface command is used to control the advertisement of routing information. The command enables the suppression of routing updates over some interfaces while it allows updates to be exchanged over the other interfaces.

$1.$ Setup up the following topology on Packet Tracer

$2.$ Configure IP addresses on the R$0$ interfaces

$3.$ Repeat the same configurations for Routers $1$ and $2$ using the addresses on the topology above.

$4.$ Now we will configure EIGRP on the routers starting on R$2$

$5.$ Repeat the same steps for Routers $0$ and $1$

$6.$ Go back into Router $2$

Now run the show ip eigrp neighbors command, you should see both neighbors.

Insert a screenshot of the command below with both neighbors shown

$7.$ Now run the show ip protocols commands verify that EIGRP $1$ is the protocol

Check out the metrics being used....K$1$ and K$3$ should both be used

$8.$ Now run the show ip route on Router $2$ to make sure that the $192\mathrm{.}168\mathrm{.}0\mathrm{.}0$ network is in our route table $($which was learned via EIGRP$).$

Insert a screenshot of the command below with both neighbors shown

$9.$ Go back to R$2$ and we will make the G$0/0$ interface passive

$10.$ Insert a screenshot of the message which appears telling you that you connection to the neighbor is $$down$$ as the hold time has expired.

$11.$ Now run the show ip eigrp neighbors command on R$2$ and that neighbor should not appear on the list.

Insert a screenshot of the command below with that neighbor gone.
