fault_tolerant_router won't return
Trying to set up fault_tolerant_router
[URL="https://github.com/drsound/fault_tolerant_router"]/URL]
on a standalone i7 desktop, to solve a particular problem in our office that we can't seem to fix with a commercial router.
It rolls over as soon as the primary link goes down, but won't return to the primary when that link comes back up.
The network config is
link 1 (enp1s0) -> outbound router 1
link 2 (enp2s0) -> outbound router 2
link 3 (enp3s0) <-> Office LAN
I've attached below the 3 ifcfg-xxx files from /etc/sysconfig/network-scripts, and also /etc/fault_tolerant_router.conf
Anyone out there using ftr successfully, who can see my (OBVIOUS?) error?
Any advice greatly appreciated.
