Hello

would you show me the way how to realize following scheme: router 2801 get connected to ISP_A with 5 Mbit Internet bandwidth and to ISP_B with 1 Mbit, I need load balance my outgoing traffic using 2 links, not "load share", I hear that BGP can do load balance, but CCNP official study guide say that "BGP select only the best one route or can do balance 50/50 per two links" so I in mess, please assist me how to realize it

Thank you!

I see this not possible without manupulation of the outgoing traffic.

Do you have bgp table from both ISP's ?

If yes, you will need to do some policy routing to state that you will prefer ISP_A to reach that all internet (as it is 5 Mbit) and prefer ISP_B (as far as ISP_B link is up)to reach ASxxx, ASyyy, etc.. This is not very flexible solution and will need fine tuning.

HTH,
