Re: MPLS network - split into sites or have flat.

Use the AD Sites Object.

Anything slower than a fully syncronous (same speed both ways) 10mbps link
is considered "slow". Some might argure that anything less than 100mbps is
"slow".

It is not all about bandwidth either it is about the link being over the
internet which will inevitablly at some point "go down". You want the LANs
to still be survivable in such a case. So have a local DC with DNS, DHCP &
WINS running at the local Site. This will keep local logins and local
authentication functioning if the links drops out.

Hi All
We are opening a branch office and have ordered a 2MB leased line at each
site and an MPLPS network that links them together.
The leased line suppliers think that I do not need to set up seperate
'sites', and that DNS, dhcp and authentication can be done over the WAN
link
without too much bandwidth being hogged.
I also use an IT support company, and they tell me using WAN link for dns,
dhcp and authentication would have an adverse effect on the WAN link
speed -
and recommend against it. They think I should set up two sites, and so
have
inter-site replication which is a more efficient use of bandwidth.
Given out computer needs are failry light and standard (MS Office, Email,
an
ERP which would only be accessed from one site only, and some file
storage) I
am not sure.
I realise this is quite an open ended question too, but has anyone any
opinions on this please
TIA
Lewej
