Site Link Bridges - Do I need them?
Posted on 2003-11-21
Hello, thank you for visiting my question...
I have a total of 9 offices. I have site to site VPN's connecting all 8 branch offices to the corporate office. No site to site VPN's between branch offices (So the enterprise network is not fully routed)
A - Corporate Office (corpdom.com)
B - Branch1 (corpdom.com)
C - Branch2 (corpdom.com)
D - Branch3
E - Branch4
F - Branch5
G - Branch6
H - Branch7
I - Branch8
Currently... 2 out of 8 branch offices have joined the corporate domain and I have configured my sites and services as follows:
Site Link Bridges:
All subnets are in place and everything is working like a charm. You know what that means... time to break something!
Lets say I want to join the remaning 6 branch offices to the corporate domain. Are there three ways to do it?
1) Create 28 additional site to site VPN's to make the enterprise network fully routed. This way I will not need to create any site link bridges. (Not preferred - too costly?)
2) Forget the additional VPN's and create 28 Site Link bridges (AD Replication may be too slow?)
3) Forget the VPN's and the Site Link Bridges and just create 8 site links? A-B, A-C, A-D, A-E, A-F, A-G, A-H, A-I (this is my question...)
Do I need all the site link bridges? Will AD Replication work as it should without them? If I do need them, would it be in my best interest to make the network fully routed?
