Configuing Interior Protocol for whole environment

[jkush12]

• Assume the IGP (R1-R2-R3) was formed by a corporate merger. In detail, come up with a conversion plan to route the environment with only one interior protocol.  Include the configuration commands/changes you would need to make.

I have been trying to figure out the best way to do this and I thought EIGRP would be a good way to do this but I am not completely sure if that would be the best. Any suggestions on how I would go about doing this properly.

Hi

Please correct me if Im understanding wrong but they are merging companies, so you could use redistribution:

Router 1 (fa0/0) ----- (fa0/0) Router 2 (fa0/1) ----- (fa0/1) Router 3

Router 1

Interface loopback 0

ip add 1.1.1.1 255.255.255.255

int fa0/0

ip add 10.12.0.1 255.255.255.0

router eigrp 100

network 1.1.1.1 0.0.0.0

network 10.12.0.1 0.0.0.0

Router 2

Interface loopback 0

ip add 2.2.2.2 255.255.255.255

int fa0/0

ip add 10.12.0.2 255.255.255.0

int fa0/1

ip add 10.23.0.2 255.255.255.0

router eigrp 100

network 2.2.2.2 0.0.0.0

network 10.12.0.2 0.0.0.0

redistribute eigrp 200

router eigrp 200

network 10.23.0.2 0.0.0.0 

redistribute eigrp 100 

Router 3

Interface loopback 0

ip add 3.3.3.3 255.255.255.255

int fa0/1

ip add 10.23.0.1 255.255.255.0

router eigrp 200

network 3.3.3.3 0.0.0.0

network 10.23.0.1 0.0.0.0 

The redistribution can be made on the edge router, I assume R2 is an edge router. 

Hope it is useful

That is what I thought aswell but I was not 100 percent sure. For me, that would make sense since it says corporate merger and you would just redistribute between the routers. I will come back with an update on this. Thank you for the help by the way. I will try to get more info on this but for now thank you.

Hi

You are welcome, please keep me posted.

I was told it is a merger between two companies so I think you nailed it.
