Hello, i have two completely different networks and i need to interchange some vlans from one two other.
My idea is to create vlans in both interface and bridge it, for example.

Vlan5.Ether1 <--> Ether5.Vlan7

Can this be done?

Yes you can do that.

Make bridge and add VLAN's to bridge and that working.

Thanks, i suppose that but i prefer to be sure.
To handle 1Gbps traffic what rb do you think i need???

You can check bridging performance on each router model, but bridging is not CPU intensive and most gigabit models are capable of it.
But I would recommend at least a 850Gx2 or a 3011, since it will allow Gbit performance on NAT if needed.

Hello, i finally bought two CCR1009 with LCD and SFP+
I hope it can move 1 Gbps

You can move a lot more than that... Bridging + 1Gbps NAT full speed takes at most 10% processor power on my 1009.

Opsss i bought to much, what is in the display shown? I hope i can show traffic use of the bridge.

The real traffic, for now, is a couple kbps but i will implement a OSPF and BGP network around it.

Thanks for all.
