Big-ip default route - rule of thumb?

I'm wondering if there's a "rule of thumb" for configuring a default route, ie. which network to use if there's just one. For example, a 2200 with...

 

Management access: 192.168.10.0

 

Vservers:192.168.110.0

 

Backend networks:192.168.20.0, 192.168.30.0 and 192.168.40.0

 

(assume all use a /24 mask)

 

Thus in this scenario, which network should I use for my default route? I've seen some articles about configuring multiple routes, but no "best practice" if there's only one.

 

Thanks!

    there is no best practice because no best practice for that. this completely depend on your business needs which interface to use for default route. However you need keep in mind that big-ip uses two types of routing tables - tmm for service traffic and linux for mgmt and daemons running in linux environment. Some tmm routes being injected into linux routing table by default and their metric is higher then linux native routes.
