Hi! I try to implement HA-configuration with two ASA and two 2821 routers.
! [ASA-1]  !
![Local] < >< >[ISP]!
! [ASA-2]  !
Is it correct configuration?
1) Configure EIGRP on every 2821 to distribute default gw from ISP to ASA
2) Configure EIGRP on every ASA
3) In Active/Standby mode standby ASA don't participate in routing process and don't forward traffic.
Do you know cisco's documents about HA-design with ASA 8.0 and EIGRP?
I would just forget both the EIGRP, and HSRP unless there is some real underlying reason you need thes for this particular type of setup. You don't need either HSRP or EIGRP for Active/standby config. The attached config snippet is all there is to this setup, of course you would simpy add your default static route such as "route outside 0.0.0.0 0.0.0.0 . Let me know if this helps!
