Manage outbound traffic - Link Controller

Hello Friends:

 

Had not yet had the opportunity to install a LinkController. My experience has been directed to LTM, APM. So now I have a question on how the Link Controller manages the internet traffic.

 

Data query: - I have two Big-IP 2000s in HA and licensed with Link Controller only. - I have two Internet connections (ISP1 - ISP2) each with the same bandwidth. - You want to do that all Internet traffic is directed by ISP2 only and that when this supplier (ISP2) fails, navigation redirect all the other internet link (ISP1).

 

Currently you have this:

 

  • It has created a pool with two members (IP Router ISP1 - IP Rouetr ISP2) and the method of balancing is round robin.
  • We have created a virtul server (wildcard) and a resource has placed the pool of gateways.

With this configuration the outgoing internet traffic is balanced and not that desired.

 

Hope you could give me some guidance. Please, I will really appreciate any help.

 

Thanks John

    can you try priority group activation setting?

     

  • hello nitass:

    I had tried the placement of priority-group, but when I put in this way there are moments in which not browse the internet. That is, he becomes unstable internet (there are times when you have internet and at other times not)

    attachment settings that had placed in the pool of gatways and priorities.

    ltm pool Pool_wilcard {

    members {
            IP-ISP1:any {
            address 190.x.x.x
            priority-group 5
            session monitor-enabled
            state up
        }
        IP-ISP2:any {
            address 200.y.y.y
            priority-group 10
            session monitor-enabled
            state up
        }
    }
    min-active-members 1
    monitor gateway_icmp
    

    }

    Regards.

    have you checked tcpdump when the issue was happening? could it relate to snat ip (e.g. using invalid snat ip on link)?

     

  • Hi:

     

    Yes, Snat this in Automap currently.

     

    When the Internet becomes intermittent traffic from the TCPDUMP nothing is displayed. That is, all traffic stays floating IP F5.

     

    Regards.

    what tcpdump command and filter did you use? does it capture both snat ip?
