Dual ISP & Dual ASA scenario

 Hi All,

 Scenario:-
 2 ISP on 2 different routers.
 2 ASA (each ASA is connected to each routers directly)

                               ISP1 ISP2
                                 | |
                              Rtr A RtrB
                                | |
                              ASA 1 ASA 2
                                \ /
                                  \ /
                                    \ /
                                     SWITCH 1

Requirement:-
Load Balancing/Load Sharing between both the ISP's.
Active/Standby between both the ASA

Solution:-
AS path prepending to be used for load sharing by running BGP.
Configuring 2 default routes one for ISP1 and another as back up for ISP2 on
ASA.
PBR configuration on RtrA to forward the traffic on RtrB.
Stateful Failover on ASA

Kindly do let me know if this is good solution. Also, if there are any
challenges to implement this solution. If anyone has another better solution
please suggest.

Cheers,
Nick
