Chapter 6

Inter-VLAN Routing

10.

C, D. The command set route default and the command set
route 0.0.0.0

are the same command and can be used to set a

default gateway on a 5000 series switch.

11.

C. The

command

interface vlan #

is used to create a VLAN inter-

face. The IP address of the interface is then configured with the ip
address

command.

12.

C. An external route processor configured with subinterfaces does
not need a shutdown performed on each subinterface, only the main
interface. However, an internal route processor must have a no
shutdown

command performed under every VLAN interface.

13.

C. The Route Switch Feature Card (RSFC) is a daughter card for the
Supervisor Engine II G and Supervisor III G cards. The RSFC is a fully
functioning router running the Cisco IOS.

14.

C. The RSM commands are the same as they are for any Cisco IOS
router, and the show running-config is used to view the current
configuration.

15.

D. To view the routing table on the internal processor, use the show
ip route

command, just as you would with any IOS-based router.

16.

C, D. The command show interface vlan # and the show
running-config

command will display the virtual hardware address

of an interface if set.

17.

C. The command

show interface vlan #

will show both the vir-

tual MAC address if set and the burned-in address (BIA) of the VLAN
interface.

18.

B. A switch port must be configured with a trunking protocol to run
ISL inter-VLAN communication to a single router interface.

19.

C. The subinterface command encapsulation type vlan is used to
set the VLAN ID and encapsulation method on a subinterface.

20.

C. VLAN 0, which cannot be accessed by an administrator, is used to
provide support for the communication between the RSM and the
Catalyst 5000 switch.
