BIG-IP Design Issues

Hi,

 

 

I am pretty new in F5 world and I have 2 design related questions:

 

1. Is it possible to create 3 VLANs (with Web servers farms) on 3 different DMZs connected to a Firewall (ex: Cisco ASA) and have the LTM in a different DMZ connected to the same firewall through a 802.1Q VLAN tagged trunk?

 

2. I want to have 2 datacenters in Active-Active mode; can the Advanced Routing Module check the availability of my servers on one particular site and if they are down, send a routing advertisement to my router (ex: OSPF) to change the route to those particular servers to the second datacenter?

 

 

Thanks very much for your help.

 

 

Fouad

    Hi Fouad -

    1) Should be, if I understand the question correctly. If the network looks like this:
    
          LTM
           |
          DMZ0
           |
        Firewall
        /   |   \
    DMZ1   DMZ2  DMZ3
     |      |      |
servers  servers  servers

    then you can use static routing on the LTM to route traffic bound for each DMZ subnet via the firewall interface.

    2) Yes

    You're very welcome.
