DHCP Client on a Management Interface
These conditions apply when you enable a management interface to operate as a DHCP client.
The management default route is added with the gateway as the router IP address received in the DHCP ACK packet. It is
required to send and receive trac to and from other subnets on the external network. The route is added irrespective when the
DHCP client and server are in the same or dierent subnets. The management default route is deleted if the management IP
address is released like other DHCP client management routes.
ip route for 0.0.0.0 takes precedence if it is present or added later.
