The destination address route configuration is not applicable when multiple IP addresses with different next hop addresses are planned for the gNodeB. Destination address route configuration is used when a single IP address is used by the gNodeB and the next hop address and outgoing interface do not need to be configured. In the case of multiple IP addresses with different next hop addresses, direct route configuration should be used. Direct route configuration requires that the IP address, next hop address, and outgoing interface all be specified for each IP address.
