I have two FreeBSD routers.  I would like both locations to share the
10.10.0.0/16 network.  If I were using Cisco routers I would use
extended VLANs.  How would I do that with FreeBSD routers?

I already have a tunnel set up and routing different networks in the
192.168.0.0/16 range.  

Router A:

ifconfig em2 inet 192.168.1.1 netmask 255.255.255.0
ifconfig gif0 create 192.168.1.1 192.168.2.1 netmask 255.255.255.0 tunnel <routerA> <routerB>
route add 192.168.2.0/24 129.168.2.1

Router B:

ifconfig em2 inet 192.168.2.1 netmask 255.255.255.0
ifconfig gif0 create 192.168.2.1 192.168.1.1 netmask 255.255.255.0 tunnel <routerB> <routerA>
route add 192.168.1.0/24 129.168.1.1

This routes traffic between 192.168.1.0/24 and 192.168.2.0/24 as I would
expect.

The docs say I can use a tunnel with a bridge, which seems like it would
do what I want.

Router A:

ifconfig em3 inet 10.10.1.1 netmask 255.255.0.0
ifconfig bridge0 create addm em3 addm gif0

Router B:

ifconfig em3 inet 10.10.2.1 netmask 255.255.0.0
ifconfig bridge0 create addm em3 addm gif0

I cannot ping 10.10.2.1 from router A or 10.10.1.1 from router B.

Should I be able to use a bridge this way?  Am I missing some piece?

Is there an easier/better way to extend a VLAN with FreeBSD routers?

Thanks!

Dan
