Hi, i have to setup LB URL in F5 located in one location poiting to Nodes at another location?

F5 is installed at DC: Pool members are located at Other Site URL Setup based on the host DC IP ranges. Pools members are listening properly and showing up on the designated ports.

 

But when tried to access via the URL, its not working. showing error, unable to establish communication!!

    Example: Site 1: F5 is present with the IP range 10.10.10.0/24 Site 2: Pool members are present: 10.11.10.0/24

     

    url: abc.def.net:22 pool members: 10.11.10.1:22 and 10.11.10.2:22

     

    Communication from F5 to these pool members 10.11.10.1 and 10.11.10.2 is happening via MPLS.

    Can you login to actual LTM, where VIP has hosted and validate the 

    telnet/curl
    session from LTM CLI and check if pool is getting traffic?

    • Bypass the LTM & try to access directly to backend server via putty/ssh tool 
      10.11.10.2:22
    • Did you check the route/firewall if any blockage between two DC?
    • Check ping & traceroute result from one DC to other DC VIP?

    Hope it will help to drill the issue.
