How do I distribute default alternate route in my scenario using BGP on Check Point?

[Blason_R]

Hi Team,

I have a below scenario FW and FW2 both are in eBGP and are Check Point 6000 series firewalls. while FW1 is having BGP peering with R1, R2, R3

Both FW1 and FW2 are having different Internet pipes. So I would like to achieve for hosts 192.168.47.98 whose default gateway is 192.168.47.96 while default gateway for 192.168.47.99 is 192.168.47.95.

So if internet pipe fails on FW2 it should route through FW1 and vice -versa. I am not sure how to configure the default gateway in BGP as a alternate router while peering with FW1 and with Routers from FW1 is  working fine.

Between FW1 and FW2 eBGP is configured using link10.30.30.20 & 10.30.30.40. Can someone pls help me on BGP?
