Campus Network & OSPF / EIGRP

[m.lesnick]

I'm presently shaping a network with 15 routers. The network is all cisco with EIGRP running on all routers with VLSM enabled. I'm considering moving to OSPF on WAN links and EIGRP on LAN. Routers are 2600 series and core is a 2948GL3. Network is presently stable and runs good. Should the move be made? I have read many different opinions on moving towards OSPF vs EIGRP but I'm not convinced completely. Views appreciated....

View 1: I'm all for simplicity, having just one protocol routing your network is easy to troubleshoot and configure for tuning.

View2: I'm also one for, If it aint broke, don't fix it.

I tend to lean for view 1 right now. Using OSPF route summarization, you should have a fairly 'quiet' network. OSPF is a low bandwidth protocol if you have a stable network. Have fun!

Note: You can run both protocols and move them over to OSPF as you desire.

Sitck with one routing protocol.... On this size of a network, either one (ospf or eigrp) will work fine. Which to choose is going to depend in the direction you think the network will grow--I would guess you will tend more towards hub and spoke designs, so I would say eigrp.
