AltocumulusAuto-Last-Hop vs Routing
Hey guys, cause of an active-active DSC setup I don't want to work with routes. (Two gateways for the same subnet) I thought I could manage it with the "Auto Last Hop" feature which is enabled. Un...
However I solved it with route domains. I thing it is the smartest solution for this deployment.
Hi NetCohort
Are your pool members in a subnet directly connected to the BIG-IPs?

AltocumulusHi,
unfortunately not. That would work, but the real servers are behind my next hop.
Because I have to route same subnets (because real server may running on the same site) to different gateways to connect my real servers, it looks like that I have configure route domains per site.
Any other idea?
route hop (firewall) <-> active-active DSC <-> route hop (firewall) <-> real server
This article seems like it might fit what you're looking for: K15582: Configuring multiple default routes on the BIG-IP system (11.x - 15.x)
The BIG-IP has the ability to specify an LTM pool as the "hop" for a default route, where you might be able to have both of your gateways in the pool.
Another option could be to look into dynamic routing protocols.
