HI, I am wondering what is "better" (faster/other reason) for wireless p2p link between two lacations. Make it as router to router bridge - one subnet or create subnets between every 2 interfaces on link.

Bridge:

INTERNET ---- ROUTER A (10.0.0.1) -------- (10.0.0.2) ROUTER_WIRELESS_B ********* wireless ********* (10.0.0.3) ROUTER_WIRELESS_C ------ (10.0.0.4) ROUTER D (192.168.1.1) ------ (192.168.1.2) LAN

Routing with subnets

INTERNET ---- ROUTER A (10.0.0.1) -------- (10.0.0.2) ROUTER_WIRELESS_B (10.0.1.1)********* wireless ********* (10.0.1.2) ROUTER_WIRELESS_C (10.0.2.1) ------ (10.0.2.2) ROUTER D (192.168.1.1) ------ (192.168.1.2) LAN

Bridge means less package processing on the involved devices ... which means lower delay and possibly higher throughput. However, bridge also means broadcasts (including ARP requests) for the whole subnet will hit all the wireless links (presumably bottlenecks) ... which means somewhat reduced throughput. Same goes for any multicast traffic if IGMP is not in full function (and that's not easy to set-up).

Which effect prevails depends on amount of broadcast/multicast traffic ...

Ajaj. So routing? But if TROUTER A and ROUTER D is "hideing" wireless link (subnet 10.0.0.0/24) from rest of the LAN, isnt it OK for bridging?

In your particular case, the scheme with bridging where only 4 hosts would be in the 10.0.0.0/x network is fine, as there won't be much broadcast traffic between these hosts.

Thanks guys, thats what i wanted to hear
Btw would u mind give me some idea for routing in whole network?
