We're about to implement pVLANs in our IDC. I have a burning question
regarding addressing and cross-customer access when using pVLANs. Consider
this:
1. IP address block used for customers (valid routable IP block) is say
x.x.x.x/21
2. Imagine that we have a customer, who runs popular database (for example,
geographic map database) and we have few other customers who wish to use
this database from their applications running on their servers, so they will
need an access to first customer's server, but only to one service, so
placing them all together in community vlan will not cut anything besides
making first customer very pissed off.
3. Giving all customers netmasks of /32 and assigning promisc port netmask
of /21 won't help for obvious reasons.
I'm thinking about giving rfc1918 addresses to hosted customers and NATing
them on 6509's MSFC to provide this functionality. Any other ways of solving
this problem?
Or is there a problem? ;^)
