MX64 with primary WAN (1) connected to a fiber base service provider 500M pipe and secondary WAN (2) (AKA LAN 4) connected to AT&T LTE backup router. Public IP's are on both networks.
We recently discovered during hard failure of the WAN 1 services automatically move to WAN 2 as expected. However, when WAN 1 service was restored about 30 minutes later MX64 did not force back all services to WAN 1 thus leaving some devices and VOIP services traversing WAN 2 which later cause data overages on the AT&T LTE backup.
We are NOT load sharing WAN 1 is primary.
Any guidance the community can provide is appreciated.
What you are describing seem to be related to our issue.
Agree the VOIP services are always communicating with the hosted voice switch my assumption based on your response is we need to have the device cease to communicate, that seems to be problematic.
I contacted our VOIP service provider today who sent me screen shot showing some phones on the primary IP and some on backup IP while primary is up, which is the real issue. There support team recommended reducing the DHCP lease time..... but I am not sure that is really going to do anything to resolve this issue.
Are there any fixes or setting we can make in the Meraki that would help reduce the time Meraki waits before switch the device back to primary?
