    Connecting two sites

    Hi All,

    I have a query which I believe I know the answer to but just need confirmation that it is right.

    Basically we now have two sites and in the summer there will be a direct connection (or as direct as BT will allow) put in place. We are getting rid of the servers from Site B and joining the computers from site B to site A's domain. I believe I would need a router or layer 3 switch to point all the switches to Site A. We currently have 1 layer 3 switch so would this be enough to achieve what I need?

    I admit this isn't my strong point so any help would be appreciated.

    Depends what technology BT are using to provide the link and how its presented to you.

    You need two router one on each site but have you considered pfsense as the thing doing the routing it will be easier to configure.

    I admit my knowledge on this isn't great but it was my understanding you could use layer 3 switches to do this? Never used pfsense before but will look into it now

    Thanks

    If this is correct no router needed, plug the a end into your lan, the b end into a switch and the link will be trasparent, it will pass all traffic as if it is an extension of your lan, think of it like a fibre link to a remote building.

    Thanks Jamesreedersmith. With it getting closer to the summer I wanted to make sure everything was in place and I started to double guess myself.

    I'd still have a DC or RODC at the other end, otherwise all traffic will go down the 100Mbps PTP.

    We have about 40 computers at site B. But at most we will have 30 users logged on with about 10 being logged on from the morning to end of the day so should be able to cope with that.

    Worse case scenario though, if the PTP link goes down, users at site B are stuffed. If there's a physical server on site, they can still logon and do certain tasks with access to some resources temporarily unavailable.

    This also minimises traffic over the PTP, so it's only web or replication traffic mostly.

    Yeah I understand that, but with most things the decision was financial. Our current network setup is not ideal and it will be migrated within 12 months at which point we will look at this again and see where we stand.

    The sites are 300 yards apart so we can put workarounds in place if needs be

    Is there no line of sight between the two sites? we were lucky and just about had a view so managed to get a gigabit laser link in place rather than paying BT for a slower link

    There is but we were quoted the same price for the same speed by a few different companies so felt we would go with wired over wireless.
