my cisco isr 819 constantly cycles between the gigabyte interface and the cellular...? _i have the device configured for auto failover with the gigabyte interface being the primary and the cellular as backup. _i used Cisco Configuration Pro to configure the router. _i have attached the router config for expert evaluation.....thanks in advance.
In this case, it is likely the issue is caused by the NAT translations. After reviewing your configuration, I suggest adding an EEM script to clear the IP NAT translations once the primary route goes down. Here you have the EEM script suggested:
event manager applet IP_NAT
event track 1 state any
action 1.0 cli command "enable"
action 2.0 cli command "clear ip nat translation *"
