Multiple "Outside" interfaces and routing lookups

What Lies Beneath,

Thanks for your answer. As if you couldn't tell my LTM knowledge is limited to VIP's and Pools. I never heard of Auto Last Hop but that does sound like something I'll need if we move to multiple interfaces on the outside (more to come on this).

In a question surrounding design I'll put this past you for your input if you have time. Ultimately here are the requirements.

• We have two VIP subnets (say 10.10.10.0/24 and 10.20.20.0/24).
• There are multiple pools underneath which aren't at issue.
• We would like to keep all VIP addresses the same to ease the switch to a new site.

Additional Questions: Can the LTM have one outside netblock (say 10.30.30.0/24) with the current VIP's still on 10.0.10.0/10.20.20.0 (as long as a FW or router can route the 10.10.10.0 and 10.20.20.0 traffic to the LTM 10.30.30.0 address?

If it doesn't need to have an interface per VIP subnet that makes for a much easier transition.
