Multi-homing for this topology - Please suggest

[AyushKhurana21]

Hi Guys,

I am posting this topology and I am stuck in this weird situation..
Due to some submarine failure we have a new ISP (ISP3) but it's not available at core but at Internal Edge core..

Can you please suggest how I can achieve load-sharing between these 3 ISP's..?

Thanks
Ayush

Hello,

at first glance, I would say your best option would be to configure policy based routing and send some of your traffic out over the ISP3 link. Are all your internal networks connected to the Internal Edge Core Router ?
