Hi.I have 2 ASAs in failover and the provider that is providing the internet link and the link to our main office has done the following.
Over the same optical cable I have 3 IP ranges coming.First is a point-to-point range for connecting our devices,second one is a directed IP route range with 4 usable addresses and the third over which comes the range for connection to the main office with plenty of usable addresses.
How would I make a failover configuration for this kind of link?I suppose I can make different subifs and VLANs for each range but as I understand it I need 2 addresses to make failover viable.
Can a failover be done at all as I have only 2 addresses available in the point-to-point range between our devices or is there some way around this?
