Route Domains

Hello Everybody,

 

Would you use Route Domains only if there are conflicting IP ranges? E.g. multiple customers

 

Or can you use Route Domains to segregate external and internet applications.

 

E.g.

 

External Route Domain: Internet Users <--> External Firewall <--> External Switch <--> F5 <--> DMZ Switch <--> DMZ Servers

 

Internal Route Domain: Internal Users <--> Internal Router <--> VLAN: F5 VS, Pool and Nodes (one arm configuration).

 

Any drawbacks apart from the extra management?

 

Any opinions will be welcomed!

 

Thanks,
