186 IP Addressing
If multiple default gateways are assigned, only one active default gateway is
used. The active default gateway is selected according to the following
criteria:
• A static default gateway is preferred (not a dynamic default gateway).
• If multiple static default gateways are assigned, the static default gateway
on the OOB interface is selected.
• If multiple dynamic default gateways are assigned, the DHCP default
gateway assigned on the OOB interface is selected.
•See IPv4 Default Gateway for a description of how the metrics of the
routes determine which default route is chosen.
