REP limitation

[brillanmela1]

Hi 

I have question on the REP

"There can be a maximum of 22 REP segments per router." 

There is a maximum of 64 REP segments per switch.

what does these two statement exactly mean?

if you had any example to show it would be great

furthermore, are there any limitation for REP?

Thanks!

Hi Mark

thanks for your support, however it's not clear what it mean 

"maximum of 22 REP segments per router"

does it mean one subnet can only contain 22 segments? but contradict to "There is a maximum of 64 REP segments per switch."

that what I still confused

thanks!

No not subnets , it means a router no matter how many ports are available can only be broken into a maximum of 22 segments and only 2 ports per segment  , physical ports are assigned to segments , REP is another form of STP so its not based on ip its more layer 2
