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.

  1. Static Routing:

  2. OSPF Routing:
    Figure5.    OSPF Routing Entries of SwitchA

    Figure6.    OSPF Routing Entries of SwitchB

  • Run Ping command to check the connectivity between PC1 and PC2.
