Migration of 2 ISPs in one network.

[anura_cp]

Hi all,

As you all can see the network diagram specified by me.

i will elaborate this in short,

I have 2 different isps terminating on two different routers(ISP A on Router A and ISP B on Router B).

My existing network is running through Router A, i want to migrate another ISP i.e., ISP B link in the existing network.

Router B is preconfigured with BGP, i dont have access to router B,

Now my lan segment is natted on both the ASA , with public ip going towards Router A.

My wan switch is blank till the time.

Now i want that my outgoing traffic should go through ISP A as well as ISP B.

I dont have any empty port on both the ASA.

Can i achieve this by using BGP, if yes plz provide me solution.

Thanks in Advance.

Hi,

You can achieve this by running a dynamic protocol between the ASA and the two border routers. This way you can have load-balancing between both ISPs.

You could put Router-A, Router-B and the ASAs in the same subnet (as you don't have another port on the ASA) and run OSPF.
