Maximum number of hosts

Re: Maximum number of hosts

Layer 3 router segments broadcast, and the number of the maximum hosts
depends on
subnet mask? therefore with /24 subnet mask, there can be 254
hosts...and more with smaller number of subnet.
Is that right? ^^;;
:) Yep - but that's not my point.
I seem to remember that Cisco recommend not more than 500 hosts on a
broadcast segment - that would be a /23 subnetmask, but i cant find this
figure anywhere when googling....

Re: Maximum number of hosts

that number sounds familiar to me as well - although since this is tradeoff
in cost of L3 vs simplicity of L2, the recommendation is likely to change
over time as hardware capabilities change.
have a look around in the ref designs area:
www.cisco.com/go/srnd
there is a limit for a collision domain size on Ethernet of 1024 (1023?)
devices - which is based on the statistics of the collision backoff scheme
for CSMA/CD.
Again - no one in there right mind would try to get close to either of those
limits these days, since routing is so cheap.
