4. Configuring an interface

Basic IPv4 and IPv6 address

First we will take a look at what interfaces we have and review them quickly.

We can use the same IOS command we are already familiar with – show ip

interface brief

RP/0/7/CPU0:R1#

RP/0/7/CPU0:R1#sh ip int br

Interface IP-Address Status Protocol

MgmtEth0/7/CPU0/0 unassigned Shutdown Down

MgmtEth0/7/CPU0/1 unassigned Shutdown Down

MgmtEth0/7/CPU0/2 unassigned Shutdown Down

GigabitEthernet0/3/0/0 unassigned Down Down

GigabitEthernet0/3/0/1 unassigned Down Down

GigabitEthernet0/3/0/2 unassigned Up Up

GigabitEthernet0/3/0/3 unassigned Up Up

MgmtEth0/6/CPU0/0 unassigned Shutdown Down

MgmtEth0/6/CPU0/1 unassigned Shutdown Down

MgmtEth0/6/CPU0/2 unassigned Shutdown Down

RP/0/7/CPU0:R1#

Here you can see that we have an RP in Slot 6 and 7 (Mgmt) and a 4-port Gig

card in Slot 3. For this lab, interfaces G0/3/0/2 and G0/3/0/3 are pre-

cabled to another router and are currently UP/UP right now.

Let configure an IP address on G0/3/0/2 of 150.1.12.1 with a mask of

255.255.255.0

First, let’s look at the running config on the interface now:

RP/0/7/CPU0:R1#

RP/0/7/CPU0:R1#sh run int g0/3/0/2

Thu Mar 29 18:38:29.942 UTC

% No such configuration item(s)

RP/0/7/CPU0:R1#

As you can see, it says No such config, it is telling you that it is

unconfigured.

RP/0/7/CPU0:R1#conf t

Thu Mar 29 18:38:31.891 UTC

RP/0/7/CPU0:R1(config)#int g0/3/0/2

RP/0/7/CPU0:R1(config-if)#ip add 150.1.12.1/24

1 2 ... 9 10 11 12 13 14 15 16 17 18 19 ... 104 105
