Ok, so I have an 1841 router. Router is doing PAT for inside hosts and phones, and is connected to two ISPs.
Solution desired is that one of the ISPs get used as a "backup". So SLA policies go in, and voilla. It fails over and starts using the backup isp, until that backup isp comes back up (via a pingable address in their network).
The only trouble in paradise is this:
Existing PAT translations do not get cleared, and so devices that are talking constantly (such as SIP devices) always have existing translations, and thus do not appear to fail over until they somehow create a new xlate (for example, rebooting a sip device) o rmanually clearing the translations.
Data works fine as they can retransmit and create a new translation.
Is there a way, in conjunction with ip sla policies, to force a clearing of all ip nat trans * ? Or, failing that, something else I should be using to get that functionality out of this failover scenario?
Thanks in advance for your help.
Solved! Go to Solution.

This can be accomplished with Cisco EEM.
