User Guidelines
For routed management traffic:
1 Router entries are checked for applicable destinations.
2 The globally assigned default-gateway is consulted.
If DHCP is enabled on multiple in-band interfaces and the system learns a
different default gateway on each, the system retains the first default gateway
it learns and ignores any others. If the first default gateway is lost, the system
does not revert to an alternate default gateway until it renews its IP address.
Using this command, the administrator may manually configure a single,
global default gateway. The switch installs a default route for a configured
default gateway with a preference of 253, making it more preferred than the
default gateways learned via DHCP, but less preferred than a static default
route. The preference of these routes is not configurable.
The switch installs a default route for the default gateway whether or not
routing is globally enabled. When the user displays the routing table (e.g.
show ip route ), the display identifies the default gateway, if one is known.
Use the show ip route static all command to display the configured static
routes and preferences.
The VRF identified in the parameter must have been previously created or an
error is returned.
Only IPv4 addresses are supported with the vrf parameter.
This command is only available on the N3000/N3100/N4000 switches.
