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.

This value might vary for the same route between two devices, mainly over a public network, depending on the network load and speed, and it is not a consistent value. The MTU size can also be different for various types of traffic sent from one host to the same endpoint. IPv4 Routing 403
