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 …
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.
