After you have identified which systems to include in the seed file, you might want to include multiple seed entries for systems that have multiple IP addresses. Routers, for example, have multiple IP addresses.
The discovery process will realize that the multiple IP addresses actually belong to a single system. Accordingly, the IP Manager will be able to reach the system by using an alternative address if the primary address is inaccessible, due to a failure, during the initial probe of the system.
After a system is discovered and all its IP addresses are known, the IP Manager will automatically try up to 10 different IP addresses to route around failures and reach the system.
