Cisco firepower 1150 multi internet/ISP connection

[msaeed]

dose cisco firepower support multi internet/ISP connection? and do it aggregates all the connections or work as load balancing?

On this excellent document, Cisco talk about Primary and Secondary interface.(Slide 36) But on the Layer 3  field, you can have only one IP address. I assume that this Firewall does not support multi ISP neither aggregated nor loadbalancing. What you can do is switch over between ISP using some IPSLA or Policy. But not 2 ISP at the same time.

i do not believe you can aggregate the bandwidth with different ISP, instead you can fail over and use Active/Active based mechanism with PBR

good example to start with :
