Hi All,
Has anyone ever used a Vwire setup with the same switch?
Basically we want to loop traffic back to the same switch to another L3 router.
Here is the traffic flow.
Core-switch-->Palo Vwire in --> Palo Vwire out--> Core-Switch-->L3 router
Here are the configs on the Core-Switch I used and it does work, but wondering if anyone else has any insights use cases...etc
interface GigabitEthernet1/0/6
description to VWIRE-IN
switchport access vlan 21
no cdp enable
switchport mode access
spanning-tree portfast
spanning-tree bpduguard disable
!
interface GigabitEthernet1/0/7
description to VWIRE-OUT
switchport access vlan 22
no cdp enable
switchport mode access
spanning-tree portfast
spanning-tree bpduguard disable

This would work perfectly fine if this is how you want/need to route traffic and have the appropriate routing setup on the switch. I'm not exactly sure why you would setup a network like this, but it would work fine.

Thanks. I wanted to make sure it's possible and the network design requires the vwire to loop the same switch. Primarily to cut costs and not have to purchase a separate switch for the vwire implementation.
