Dell Networking OS installs a next hop that is on the directly connected subnet of current IP address on the
interface.
Dell Networking OS also installs a next hop that is not on the directly connected subnet but which recursively
resolves to a next hop on the interface's configured subnet.
• When the interface goes down, Dell Networking OS withdraws the route.
• When the interface comes up, Dell Networking OS re-installs the route.
• When the recursive resolution is “broken,” Dell Networking OS withdraws the route.
• When the recursive resolution is satisfied, Dell Networking OS re-installs the route.
Configure Static Routes for the
Management Interface
When an IP address that a protocol uses and a static management route exists for the same prefix, the
protocol route takes precedence over the static management route.
To configure a static route for the management port, use the following command.
• Assign a static route to point to the management interface or forwarding router.
CONFIGURATION mode
management route ip-address mask {forwarding-router-address | ManagementEthernet
slot/port}
Example of the show ip management-route Command
To view the configured static routes for the management port, use the show ip management-route
command in EXEC privilege mode.
Dell#show ip management-route

Using the Configured Source IP Address
in ICMP Messages
ICMP error or unreachable messages are now sent with the configured IP address of the source interface
instead of the front-end port IP address as the source IP address. Enable the generation of ICMP unreachable
messages through the ip unreachable command in Interface mode. When a ping or traceroute packet
from an endpoint or a device arrives at the null 0 interface configured with a static route, it is discarded. In
