Outbound Traffic Load Sharing

Hi,

I have 2 ISP (1=10Mbps, 2=2Mbps) terminated into 2 routers. Routers are terminated into 2 different sets of firewall & the firewall'are terminated into Core switches.

I want to achive traffic load sharing b/w these 2 ISP's in such a manner that a large part of the traffic goes via ISP1 & rest via ISP2. At any point of time if ISP1 has more latency then partial traffic will go via ISP2. If any of the link goes down, the entire load will he transferred to the other one.

Is this possible????

Re: Outbound Traffic Load Sharing

If your routers are running BGP, an OER config would look something like:

Border router only:

key chain key1

key 1

key-string somekey

oer border

local Loopback0

master x.x.x.x key-chain key1

Combined border/master router

key chain key1

key 1

key-string somekey

oer master

logging

!

border x.x.x.x key-chain key1

interface FastEthernet0/0 internal

interface Serial0/0 external

!

border x.x.x.x key-chain key1

interface FastEthernet0/0 internal

interface Serial0/0 external

!

throughput

delay

periodic-interval 0
