Following the first three interfaces in the output, there will be an additional interface for each VLAN. The
name of an interface will be eth0.nn where nn is the VLAN number to which the IP address is assigned. Note
that even though the interface is shown as eth0, the IP address can be reached only through interfaces to
which that VLAN has been assigned.
4.4.7 Review the new configuration.
The configuration created in this section creates three distinct interfaces for use on IBR.
a. eth0.1 is the management interface on VLAN1 (the default VLAN on IBR). VLAN1 has been assigned to
GigabitEthernet port ge0 and given the IP address 192.168.128.101/16.
This interface is isolated from the other interfaces and can be used to access the IBR and manage the
switch without allowing management traffic to traverse the RF link. Because VLAN1 is associated only
with ge0 and not ge3, VLAN1 traffic will not transverse the link.
b. eth0.2 is the data interface on VLAN 2, which has been assigned to GigabitEthernet ports ge1, ge2, and
ge3.
Traffic on VLAN2 can be sent across the RF link and out onto the network. It allows all untagged traffic
and traffic tagged with VLAN ID 2 to be sent to the network.
