Load balancing by EIGRP & OSPF


How to do load balancing on two different service provider connectivities using EIGRP. Please share the configs.

Is the same is possible on OSPF, requesting to share the configs for this also.

If you're using two different ISP's then depending on the EQ on your edge you should be looking at BGP.

Re: Load balancing by EIGRP & OSPF

Hello Sam,

as Brent suggests you should look at eBGP.

the limit of IGP protocols like OSPF or EIGRP is that the two providers cannot accept to exchange routes via your router.

using different OSPF processes or different EIGRP processes doesn't produce a load balancing effect:

EIGRP with lower AS number wins

for OSPF the first process to propose a prefix to IP routing table mantainer wins (ships in the night)

also OSPF route types are not considered.

for BGP multihoming example see

Hope to help

Hii Brent / Giuseppe,

Actually this was a question with me by interviewer. and i was bit confused about the same. :).

Please share the way to achieve the desired using EIGRP and then by OSPF.
