XConfigure the router

The router uses OSPF.

set system name=Router

#VLAN general configuration create vlan=vlan100 vid=100 add vlan=100 port=1-4

#IP configuration

enable ip

set ip autonomous=65000

add ip int=vlan100 ip=172.31.0.1 mask=255.255.255.0 add ip int=eth0 ip=10.0.0.1

# OSPF configuration

set ospf routerid=172.31.0.1 add ospf area=0.0.0.1

add ospf range=172.31.0.0 area=0.0.0.1 mask=255.255.255.0 add ospf interface=vlan100 area=0.0.0.1

enable ospf

With the above configuration, the router sends OSPF messages to switch 2. As the following outputs show, this means that:

zswitch 2 designates port 24 an All Groups port

zswitch 2 forwards the OSPF packets to uplink port 25 on switch 3, so switch 3 designates port 25 an All Groups port

zswitch 3 forwards the OSPF packets to uplink port 49 on switch 1, so switch 1 designates port 49 an All Groups port
