I have two routers 2811's one with a DS3 and the other with an ethernet feed from two different providers. I am running BGP for the providers and IBGP between routers. I haver very well balanced inbound traffic but I have 90+% of my traffic goes out of one provider. Do you know a way to me to add hops to one of my providers to try to force more traffic to the other. or any other idea ??
Do you received full internet route from both provider or you received full internet route from provider-A (>90%) and only default route from provider-B (<10%)?
If you received full internet route from both providers, do you see from the "show ip bgp" that you have two paths to the same destination? This is to make sure that iBGP is configured and working properly.
I have the same situation and my problem is solved by using two HSRP sessions. Each router is used as primary for half of the traffic (I divvied my ip space to two part for example /22 will be 1/23 and 2/23). The traffic from 1/23 is sent to the first router via HSRP and the traffic from 2/23 is sent to the other router via HSRP. This solution also provides you with redundancy in case that one router goes down.
OER is another possible option, but you may end up as test lab for Cisco bugs.
You are looking for a way to share your traffic outbound.
2 Different Providers
Both sending full routes
BGP with both peers
iBGP between your routers
What I don't understand is the bandwidth on both links? are they equal?
Have you tried shutting one bgp session down and seeing doing a sh ip bgp to see the path it takes and compare once it comes back up?
How does your internal traffic know where to go? Is there something set-up that it allways hits one router over the other? If 90% of your traffic hits one router then it will always assume that outbound because to go to the other router outbound will be one more hop.
