Hi all
I have a question regarding some routing issues we have,
we have 2 sites, each site has 2 seperate routers between them
currently we have a core switch, which routes static routes to each router, some routes go to one router and then a mixture of static and eigrp routes choose the path, with higher AD on the statics etc, however its got very messy now and become a little complicated.
what we need is to route certain subnets, or host IP's over one or the other, so we can try and load share, however I have had enough of the static routes, as they dont seem to kick in as the interface to the provider is still up etc.
They currently have HSRP on them.
what would be the best way of doing this, could we use EIGRP with offset list do choose the best route etc so we know it will fail over correctly.
whats the best way for this ?
cheers

Not sure of which hardware you have used but assuming your router is capable of configuring BGP, you can use BGP.. it will give you better control of routes IN and OUT.. Load Balancing can also be easily done.

"best way"? If your hardware supported it, I would suggest OER/PfR to manage best performance across the two routers with QoS tossed in to manage congestion.
If your hardware doesn't support it, I would then suggest either load balancing with your dynamic routing protocol and/or GLBP again with QoS tossed in.

Basically all the routers are 1900 series, one link is 16mbit the other is 32.
glbp wouldn't really work well as we route to these from a core router, how easy is pfr to set up? And can I use it with eigrp ?
Could you give example config ?

Then your mention of "They currently have HSRP on them." in your OP might be clarified.

Not particularly difficult, although initially seems somewhat daunting, because of the learning curve.
Later versions of PfR, that are PIRO, should allow usage with EIGRP.
An example? Sorry no. Used OER/PfR, extensively, before joining my current employer who doesn't use it.
PS:
If you have two unequal cost links, as you're using EIGRP, it could route across them in the same 1:2 ratio.

Hi Carl,
I agree with Joseph. From the details presented it sounds like HSRP configurations with upstream EIGRP variance is going to be the way to go. Are you able to remove the static routing and conifgure all routes to use EIGRP? This is going to give you a much cleaner and more stable routing table.
PfR/OER could be an option, but I think that might be making it too complicated. Get the 1:2 egress ratio upstream, then begin deploying advanced shaping and policing feature sets if needed.
