Palo Alto Layer 2 bridging

Any idea on when or if PAN is going to produce the functionality to do layer 2 bridging (example, traffic on vlan 300 would be directed to vlan 3000...etc? Right now the function only seems to be possible when in conjunction with a physical interface per bridge which isn't scalable for lots of vlans like a DC. Another option is enabling the function to bridge in vwire mode 2 different vlan tags.

This is doable today, by using 802.1q for the two vlans you mention, with subinterfaces. and use the same vlan number for both. In that way, these two vlans are connected. No redirect. No rewrite. But connected together.

This has been possible for a long time already, please check out this article : Getting Started: Layer 2 Interfaces

Re: Palo Alto Layer 2 bridging

The problem I found with this however was the dependency on each bridge/rewrite interface group is per physical interface. For example if I create a vlan bridge between 2 different tagged sub-interfaces (aka e1/1.200 and e1/1.300) I have to create the bridge with not only .200 and .300, but with the physical interface e1/1 as well. This limits the scalability of this to the number of pyhsical interfaces available. It would be great if you could create bridges without the physical interface dependency.
