UIE - Source Mac Address

Question

I have two GTMs.  Each has its own ISP.  I would like traffic bound for GTM-1 through ISP1 to go to Pool Member 1 on a VS. And I would like traffic bound for GTM-2 through ISP-2 to go to Pool Member 2 on the same VS.  &nbsp;
&nbsp;Traffic is directed to the GTM via BGP, so in many cases I don't know the source IP address in advance.  Both GTMs are in the same synch group. Is there a way to direct traffic to a specific pool member if the request is from a particular mac address? Or is there a better way?&nbsp;
&nbsp;Thanks,
&nbsp;Donnie&nbsp;

You could use LINK::lasthop, but unfortunately that is not a valid command for GTM.  If your GTM's are in different vlan's, you can do this:
when DNS_REQUEST {
  if { [LINK::vlan_id] eq "10" } {
    log local0. "Connection is from RTR1"
    pool myPool-http member 10.1.1.10
  } elseif { [LINK::vlan_id] eq "20" } {
    log local0. "Connection is from RTR2"
    pool myPool-http member 10.1.2.10
  }
}

Should I apply this iRule to the WideIP?

jrahm · Answer

Yes, it should be applied to any wideIP in which this functionality is desired.
