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 traffic 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 different
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.
• Management routes added by a DHCP client display with Route Source as DHCP in the show ip
management route and show ip management-route dynamic command output.
• Management routes added by DHCP are automatically reinstalled if you configure a static IP route
with the ip route command that replaces a management route added by the DHCP client. If you
remove the statically configured IP route using the no ip route command, the management route
is reinstalled. Manually delete management routes added by the DHCP client.
• To reinstall management routes added by the DHCP client that is removed or replaced by the same
statically configured management routes, release the DHCP IP address and renew it on the
management interface.
• Management routes added by the DHCP client have higher precedence over the same statically
configured management route. Static routes are not removed from the running configuration if a
dynamically acquired management route added by the DHCP client overwrites a static management
route.
