Typical Configuration Example

Overview

Take the following topology as an example to introduce how to implement communication between PC1 and PC2.

Figure 1. Topology of Access Network

The data plan is shown as below.

Device	Interface	VLAN and IP Address
Switch A	te-1-1-1	VLAN: 10 IP address: 10.10.10.1/24
	te-1-1-2	VLAN: 4 IP address: 10.10.4.1/24
	te-1-1-3	VLAN: 5 IP address: 10.10.5.2/24
Switch B	te-1-1-1	VLAN: 3 IP address: 10.10.3.1/24
Switch B	te-1-1-2	VLAN: 4 IP address: 10.10.4.2/24
Switch C	te-1-1-1	VLAN: 2 IP address: 10.10.2.1/24
Switch C	te-1-1-3	VLAN: 5 IP address: 10.10.5.1/24
PC1	10.10.3.8/24
PC2	10.10.2.8/24

Procedure

Before configuring the following steps, make sure you have logged in the specified switch through Console port or SSH. For detailed information, see Initial Setup and Configuring the SSH Access.

Step1 In the configuration mode, configure the host name of switch respectively as SwitchA, SwitchB and SwitchC.

admin@PICOS> configure
admin@PICOS# set system hostname SwitchA
admin@PICOS# commit
admin@SwitchA#

Run the same command on other switches to change the hostname as SwitchB and SwitchC.

Step2 Configure the interface and VLAN.

Switch A

Interface te-1-1-1:

admin@SwitchA# set vlans vlan-id 10
admin@SwitchA# set interface gigabit-ethernet te-1/1/1 family ethernet-switching native-vlan-id 10
admin@SwitchA# set vlans vlan-id 10 l3-interface vlan10
admin@SwitchA# set l3-interface vlan-interface vlan10 address 10.10.10.1 prefix-length 24
admin@SwitchA# commit

Interface te-1-1-2:

admin@SwitchA# set vlans vlan-id 4
admin@SwitchA# set interface gigabit-ethernet te-1/1/2 family ethernet- admin@SwitchA# switching native-vlan-id 4
admin@SwitchA# set vlans vlan-id 4 l3-interface vlan4
admin@SwitchA# set l3-interface vlan-interface vlan4 address 10.10.4.1 prefix-length 24
admin@SwitchA# commit

Interface te-1-1-3:

Switch B

Interface te-1-1-1:

Interface te-1-1-2:

Switch C

Interface te-1-1-1:

Interface te-1-1-3:

Step3 Configure the IP address and default gateway of PC1 and PC2.

PC1:

PC2:

Step4 Configure the routing. You can configure the static routing or OSPF routing to connect network.

Connecting network through the static routing

Switch A:

Switch B:

Switch C:

Connecting network through the OSPF routing

Switch A:

Switch B:

Switch C:

Verifying the Configuration

View the routing table of each switch.

Static Routing:
