You can definitely have more than one L2 router per area... :-)

I don't know for sure, as you probably    have guessed...
   There is an ncp executor parameter called maximum broadcast routers, default value 32 iirc.
Is there an architectural limit, depends on what you mean by ethernet segment. A 10base5 segment was limited to 200 nodes. 64 L2 routers might put a hefty broadcast load on it. On an extended ethernet LAN there is likely no technical limit.

Really? I have some vague memory of some limit of an ethernet segment, but I can't recall any details now. Why 200?

Onderwerp: [HECnet] Maximum number of L2 routers?

Hello, list,

I'm trying to remember what is the maximum number of area routers allowed in a DECNET Phase IV ethernet segment. Anyone of you have that information at hand?

On other news, the old macbook I was using as home server has died, after years of service beyond the call of duty. I'm setting up my stuff using several smallish ARM computers. To be specific, now I'm running a cubietruck and and Odroid-C1 (and a raspberry Pi as router/firewall). I'm having trouble with the net connectivity, so some yo-yo disconnects from area 7 should be expected. Not so hard as last sunday, but I'm still doing quite a lot of reboots.

BTW, the SG1 multinet link seems to be down again (unless it is a problem in my side, which is completely possible).
