I have 1 7609 router with 3 ISP's will be terminating with different ASN. I do have own 1 ASN. I need to do routing based upon block size so that segment A can go via ISP1, segment B via ISP2 & segment C via ISP3 & incase any ISP goes down all traffic will be shifted to the next available ISP.
Router is connected with ASA 5550 via 1G ethernet link, The ASA is connected with 6509.
Can someone help me with configuration script of Router??
ROuter & Firewall will be connected by private IP...
