Default Routing Interface Values - Dell PowerEdge M420 Configuration Manual

switch management. The loopback interface IP address is a good choice for
communicating with the switch in these cases because the loopback interface
cannot go down when the switch is powered on and operational.
Tunnel Interface
Tunnels can be used in networks that support both IPv6 and IPv4. The tunnel
allows non-contiguous IPv6 networks to be connected over an IPv4
infrastructure.

Default Routing Interface Values

By default, no routing interfaces are configured.
When you create a VLAN, no IP address is configured, and DHCP is disabled.
After you configure an IP address, routing is automatically enabled on the
interface, and the interface has the default configuration shown in
Table 30-1.
Most interface configuration parameters are not applicable to loopback
interfaces, so you cannot change the default values. However, when you create
a loopback interface, the default values are similar to those of VLAN routing
interfaces, as Table 30-1 shows. Is this true - the show interface loopback
command lists all these features and values, but it looks like there is no way to
configure them.
