Public and private VLAN
Posted: 21 Jun 2011 14:52
Hi
I know that is not the normal configuration for Vlan topics ,also for the ip subnetting and router functions but sometimes I have to deal with situations of configuracion out of the ordinary finding a solution getting to the limit the features of the devices)
So I'm going with this one
I'm working in the multicompany enviroment and there are some conditions
-Each enterprise is different from the other one (there are 3 companies A-Router A, B- Router B and C- Router C located in two buildings )
-All the companies will share the same internet bandwith (same ISP)
-Each enterprise has the own range of IP-Public (I mean each company has a range of IP -public to manage.)
Having this in mind I got two Omniswitch 6400 (one in each building- the are connected ) and I want to know if I'm right ,or do I have to change something or I'm fully wrong with this one)
I attach a Draft with My idea is
1- to create a Public Vlan 1 containing all the ip-publics and from there distribute to other companies (companies A and B , C in the other switch(building))
2-The company A (where the Router A is) will be a private Vlan 2 ( here they are private IP)
3-This company A has a branch in the other switch that will be Vlan 3 ( here they are private IP)
For the companies B and C I think there are not any problem because they have the own routers and they are not affected for any Vlan segmentation(it's a clean layer 2 switching)
For the companie A -the router A (here the big deal) :
Will be posible to the users in the VLan 2 and 3 to go to internet take the Router A ( the users will have the default gateway the router A and also a Rip virtual interface will be enable in the 6400 to allow the users in the Vlan 3 to take the router)
Will be possible to have ping between Vlan 2 and 3 (vreating Rip interfaces)
Is it possible to implement ,some special characteristics to take into account,
Thanks
