Is there a way to map multiple bridge interfaces to a physical interface?

In case you want to know, I have virtual machines mapped to unique bride interfaces that map to same physical interface with different vlans for automation purposes and to reach external physcial devices outside of the KVM hypervisor but in some cases I need the VM's to be able to talk to each other and even others on the network. In this case I need to be able to enslave both bridges to the same physical interface.vlan let me know if there is some way to achieve this.

[root@kvmsrv07 network-scripts]# more ifcfg-1
DEVICE=p2p1.707
BRIDGE=br1
VLAN=yes
BOOTPROTO=none
ONBOOT=yes

[root@kvmsrv07 network-scripts]# more ifcfg-4
DEVICE=p2p1.707
BRIDGE=br4
VLAN=yes
BOOTPROTO=none
ONBOOT=yes

Have you tried turning on forwarding and just letting the kernel take care of routing?

As long as the 2 bridges are configured in separate broadcast domains, this should work (ie. BR1=> 192.168.1.1/24 and BR4=> 192.168.4.1/24). You should see the two entries in the routing table....

Interesting way of solving this, I will have to give it a try but right now I am toying around with openvswitch it seems to have what I need but having a problem getting it setup. Thanks for the reply

it is much less convoluted and quite versatile. it also doesnt require kernel intervention and it can use ssh/http/sit/gre/ipip/etc tunnels or even DNS traffic to connect hosts.. it's underrated for sure.
