Hello,

Does anyone have a link to documentation how to setup an OSPF network (two routers), to have a fail over.

For example: Two routers: Cable modem is primary network, LTE 4G connection is backup. I want a fully automatically fail over if cable fails. If primary modem fails (ping to Google for example), the backup should be LTE modem. Also when cable modem is back again, LTE route should be removed.

I remember this was covered during my MTCRE certification, but I do not remember any more the setup.


Anyone has an example of how to achieve this?
