IP Interface Configuration
93
Now delete the interfaces named “eth3” with the
no
interface
command:
SN(ctx-ip)[router]#
no interface external
Finally list the interfaces again to check if the appropriate interface was deleted:
SN(ctx-ip)[router]#
interface <?>
<interface> New interface
lan Existing interface
wan Existing interface
internal Existing interface
12.5 Setting the IP Address and Netmask
Each IP interface needs its explicit IP address and an appropriate network mask to be set.
Procedure
To set the IP address to
ip-address
and the network mask to
netmask
or enable IP processing for IP
interface
name
without assigning an explicit IP address, use the
ipaddress
interface configuration
command. The
ipaddress
command offers the following options:
unnumbered
Enables IP processing on an interface without assigning an explicit
IP address to the interface.
ip-address
Specifies the IP address of the subscriber in the form
A.B.C.D.
netmask
Specifies the network mask in the form
A.B.C.D
. A network mask of at
least 24 bits must be entered; that is, a mask in the range
255.255.255.0
through 255.255.255.255.
Mode
Context IP. This command also places you in interface configuration mode.
Command
Purpose
Step 1
node
(ctx-ip)[router]#interface
name
Selects the existing interface
name
, which shall be
configured
Step 2
node
(if-ip)[
name
]# ipaddress
{
unnumbered
| (
ip-address
netmask
)}
Sets the IP address
ip-address
and netmask
netmask
for interface
name
Example: Configure IP Interface Address and Netmask
To set the IP address to
192.168.1.3
and netmask to
255.255.255.0
of IP interface
lan
, use the following
commands in IP context configuration mode.
SN(ctx-ip)[router]#
interface lan
SN(if-ip)[lan]#
ipaddress 192.168.1.3 255.255.255.0
12.6 ICMP Message Processing
The IP suite offers a number of services that control and manage IP connections. Internet Control
Message Protocol (ICMP) provides many of these services. Routers send ICMP messages to hosts or
