VIP Bounceback or?
Howdy,
I have a LTM (9.1.2 40.6). My app servers connect to the db server vs (defined on the external vlan, but the pools and members all reside on the internal vlan) and this works as the GW of the app servers is not the LTM. Now I'd like to consolidate the topology and use the LTM as the GW. I tried it w/out changing the LTM config and it didn't work. I tried it by disabling the auto snat, still it didn't work.
Should the vs be moved to the internal vlan and set it up as a VIP bounceback solution? Is there an alternitive that allows the LTM to be used as the GW and still keep the vs on the external vlan?
ex: This is the current deployment and if the LTM is the GW, it won't work
virtual WR-WebDB {
destination 172.31.20.21:mysql
snat automap
ip protocol tcp
profile tcp-lan-optomized
pool WR-Servers
}
pool WR-Servers {
lb method dynamic ratio
action on svcdown reselect
min up members enable
min active members 1
monitor all SQL-Monitor
member 172.31.80.31:mysql priority 2
member 172.31.80.32:mysql
}
However, if I understand the Bounceback setup, this will work (when the LTM is the GW):
virtual WR-WebDB {
destination 172.31.80.21:mysql
snat automap
ip protocol tcp
profile tcp-lan-optomized
pool WR-Servers
}
pool WR-Servers {
lb method dynamic ratio
action on svcdown reselect
min up members enableman
min active members 1
monitor all SQL-Monitor
member 172.31.80.31:mysql priority 2
member 172.31.80.32:mysql
}
Thanks for your help.
