Load balancing with BGP

Tue Aug 27, 2013 6:49 pm

Hi,
I've a CCR1016 with BGP and one fiber connection connected to it. Next week we will receive our second connection which also supports BGP, and I would like if you can recommend me different ways to load balance both connections? Any suggestion?

Thanks,

Are you on provider assigned IP space or RIR independent such as ARIN or LACNIC?

Will you be taking a full table, partial table or default?

Hi IPANetEngineer,
We have our own ASN and IP address blocked assigned by LACNIC directly.
Our upstream provider give us only default route for the being time, but we will try to get a second pipe with partial route table (for all national IP addresses).

Thanks,

Which is more important to you latency or load?

If load is more important, i would block the partial table and only take defaults on each so you can split traffic equally between them

Once you have full tables on each, I would use local pref to divide the public routing table in half and prefer one half on each router.

There are certainly more complex ways to slice and dice the traffic, it really depends on your requirements
