[j-nsp] networks aggregation

Hi Edwardo,

EX4200 are limited to virtual-chassis extension by uplink modules only. You will also have to maintain a ring topology for you VCP connections a star topology is not how virtual-chassis works.

Virtual chassis will certainly make management easier however I think your requirements can be met by a pair of fibre switches in your main building  using virtual-chassis fanning out in a star topology using AE interface uplinks to avoid spanning-tree. You can still extend the same vlans out to all buildings. I suggest you refer back to the Juniper Virtual-Chassis Best Practice Guide if you have any queries on how VC works.

Halo,
repost, original not seem to make list?

Current we have 7 building, with 2 more being built next year.
These all have ex4200 and are link via an Rpi's, via ethernet to central building.
Messy, many subnets and cheap design, but now central building need undergo renovation in January, so need to fix the messy since  main switch and router to be moved to admin building

I am hope to have a central switch where can link remote buildings to, can use fibre, in fact prefere fibre, but need to have star configuration,

Assume switch 1 is main.

want to link 1-2 1-3 1-4 1-5... etc and use virtual chasis if possible for one big single lan, can this be done like this? I assume use fibre in uplink port of remote 4200s to switch one,  if so what recommended to use as switch one which will have 6+ fibre link into?  Be good if switch one could also take standard ethernet port as well, but not mandatory, we can use exisit 4200 in admin build.

thanks you - disclaim is networking and english are not my experience.
