Hi Experts
our organization is connected to two different ISPs , the 1st ciruit is 16 MB while the 2nd Circuit is 8 MB both circuit are terminated in different routers underlying 2900 , the organization own an AS Number along with class C address have gotten from RIPE since we r working in ME,i m advertising to Both ISPs while i receive a default route from both ISPs the question is can the load sharing occurs on both Link?i read an article mention its okay with CEF
thanks experts for sharing the info and consultancy

You mean you have a device in your LAN
Connecting to those two edge routers and load share the outgoing traffic ?
If yes what is the device type/model ?

Sorry, it's a bit unclear. Both ISP links are on the same router or two different routers? If the latter, how is (outbound) traffic directed to the two routers?
Whether one router or two, it's likely not too difficult to use both outbound links equally, but if you wanted to use them in proportional to their actual bandwidths, that might be possible too, but likely more complex.

is the outgoing traffic means traffic towards both ISP,from each router ,using BGP Local_Pref???
two edge router 2900 ,each has circuit towards the ISP

According to your requirments and since you have two different routers connected to two different ISP you can configure GLBP to unequally load balance the outgoing (uplink) traffic.
GLBP (Gateway load balancing Protocol) is configured to the LAN (similar to HSRP or VRRP).
You find furhter details ig you search with GLBP to cisco.com.
I can send you some relevant doc if you need

How is the traffic directed to the two 2900 (outbound)? For example, are the local gateways (where Vasileios' GLBP solution might work for you) or are the connect to another router or routers? Do they run iBGP and/or an IGP?

Hi Ibrahim,
please see below that might give you some help with BGP/multihoming .It also talks about load balancing as well
Let me know if anything is unclear here
