Multiple networks over the same Isp

Hello everybody, I wonder if I could find some help here.

 

I am working on 2 LTM with HA,

 

I have connected 2 internet connexion, and, on each of my Isp :

 

- a small connected network (let's say 10.0.0.0/29 for isp1 and 20.0.0.0/29 for isp2) ltm1 is .1, ltm2 is .2, virtual ltm is .3 ant isp router is .4

 

- a production network (let's say 5.0.0.0/24 for isp1 and 6.0.0.0/24 for isp2) where ip adresses are redirected from my Isp to the Ltm, and all my wide ip would be bind on, with a member on each production network -> 5.0.0.10 for isp1 and 6.0.0.10 for isp2.

 

Until now, I have configured the 2 nodes and there links, with the connected networks, bigip_link is ok, but when one of the internet access fails (for exemple isp2), both wideip members stay active, even if the apropriate link turns red.

 

I think that the isp2 wideip member doen't seems to look about the good isp2 link state.

 

Do I have ton add "virtuals" node base on the production networks to permit Link controler to associate member wideip to see that my connected network is down? or somethiong else ? I really didn't get this point

 

 

thanks for your help
