LAB 4 – Layer 2 Interface with Spanning Tree .
In Below diagram we
can see that it is layer 2 interface lab in which we have two switches
connecting two ports each to firewall thus spanning tree comes in play.
Interfaces on Palo Alto
We can see that interface eth1/1 and eth1/2 is connected to SW1 and eth1/3 and eth1/4 is connected to SW3.
Below is screenshot
of how interface config looks like.
Vlan Config is shown Below.
Layer 3 Vlan INterface.
On switches
interfaces are just configured as trunk.
Verification
ping from PC1 and PC2
lets Check Spanning Tree Status on SW3
On SW3 we can see port eth0/0 and eth1/0 are uplink to firewall.
Eth0/0 is in forwarding state and eth1/0 in blocking.
If we shutdown
interface eth0/0 eth1/0 will be in forwarding state.
Below is vlan status on firewall.
