Example of subnet routing

Prior to configuring, you must be connected to the switch Command Line Interface (CLI) as the
administrator.
NOTE:
For details about accessing and using any of the menu commands described in this
example, see the HP 10Gb Ethernet BL-c Switch Command Reference.
1.
Assign an IP address (or document the existing one) for each router and client workstation.
2.
In the example topology, the following IP addresses are used:

3.
Assign an IP interface for each subnet attached to the switch.
4.
Since there are four IP subnets connected to the switch, four IP interfaces are needed:

5.
IP interfaces are configured using the following commands at the CLI:
>> # /cfg/l3/if 1
>> IP Interface 1# addr 205.21.17.3
>> IP Interface 1# ena
>> IP Interface 1# ../if 2
>> IP Interface 2# addr 100.20.10.1
>> IP Interface 2# ena
>> IP Interface 2# ../if 3
>> IP Interface 3# addr 131.15.15.1
>> IP Interface 3# ena
>> IP Interface 3# ../if 4
>> IP Interface 4# addr 206.30.15.1
>> IP Interface 4# ena
6.
Set each server and workstation's default gateway to the appropriate switch IP interface (the one in
the same subnet as the server or workstation).
7.
Configure the default gateways to the routers' addresses.
