Enabling IP Basic Setup

Enabling IP Basic Setup
Fine-tune the IP routing functions and domain-name services for EXEC shell users, by performing the
following steps:
Optimize IP routing functions in global configuration mode:
Step 1
AS5400(config)# ip subnet-zero
AS5400(config)# no ip source-route
AS5400(config)# ip classless
AS5400(config)# ip domain-lookup
Table 3-5
Table 3-5
Command
ip subnet-zero
no ip source-route
ip classless
ip domain-lookup
In global configuration mode, enter domain-name service commands to support EXEC shell users:
Step 2
AS5400(config)# ip host mymap 172.22.53.101
AS5400(config)# ip domain-name mydomain.com
AS5400(config)# ip name-server 172.22.11.10
AS5400(config)# ip name-server 172.22.11.11
Table 3-6
Table 3-6
Command
ip host mymap 172.22.53.101
ip domain-name mydomain.com
ip name-server 172.22.11.10
ip name-server 172.22.12.11

Chapter 3 Basic Configuration Using the Command-Line Interface
Purpose
Specifies that 172.22.0.0 is a legal subnet.
Tightens security by ensuring that IP-header
packets cannot define their own paths through the
gateway.
Tightens security by ensuring that IP-header
packets cannot define their own paths through the
gateway.
Enables IP domain-name lookups.
Purpose
Creates a local name-to-address map. When the
gateway is not entered in a DNS server, this map is
useful.
Tells the gateway how to qualify DNS lookups. In
this example, mydomain.com is appended to the
end of each looked-up name.
Specifies the primary and secondary name servers.
The ip name-server command is used for
mapping names to IP addresses.
