Configuring tacacs with configuration on Common partition

Hello all!

 

When i configure authentication through tacacs the request to tacacs server leaves the inband interface 1.1 where the default route is applied. But i have the mgmt interface dedicated for this purpose and i need that request leaves the mgmt interface.

 

In another big-ip system where i don't have routes or ltm configurations in Common partition the request to tacacs server leaves from mgmt interface normally.

 

Add the specific route is not a option because the big-ip system informs there is not connected networks to apply the route.

 

See the error message below:

 

01070330:3: Static route gateway 172.26.32.254 is not directly connected via an interface.

 

But my mgmt interface is inside this subnet:

 

[root@lb786:Active:In Sync] config ifconfig mgmt

 

mgmt

 

Link encap:Ethernet HWaddr 00:23:E9:F5:24:41 inet addr:172.26.32.211 Bcast:172.26.32.255 Mask:255.255.255.192

 

Is there another way to force the tacacs request go through mgmt interface ? Do i need to create a dedicated route-domain for that ?
