I'm having some problems deploying a WLAN site-to-site connection. Devices used is a pair of Cisco 1242AG access points, with the 5Ghz radio used for the link (2.4 is unused). I've set up these devices before for simple LAN bridging with only one (the default) VLAN, which worked fine. For this project, I need a somewhat more complex setup. I've tried several ways to get this to work, but somehow couldn't match any samples and docs to what I need ...
The central site has a VoIP server which is connected both to the data LAN (in the datacenter VLAN, and reachable from all LAN segments through a router which does Inter-VLAN routing) as to the VOICE VLAN (I used VLAN 50). Additionally, the central site has a management VLAN (172) in which all switches, routers etc. are reachable for administration.
The remote site has one data vlan (default 1, mustn't be bridged to the VLAN 1 at the central site), which currently also contains the management IP subnet due to limitations in the current interconnection (leased line/MPLS). Additionally, we've started setting up VLAN 50 for the VOIP telephones.
In essence, I need the following:
- the data vlan should be routed to the central site via the WLAN link. If necessary or way less complicated, I could set up a new VLAN to route using the central router.
- the voice VLAN 50 should be bridged between both sites if possible, though if necessary, I might settle for routing also
- the management IPs should be routed, with remote site moved to its own management VLAN again as originally intended.
- for debugging issues, the APs should be directly reachable between each other (e.g. telnet to one, from there to the other) as well as in their management VLANs.
This type of configuration seems to be well beyond the scope of most (all?) documents I've been able to find, both on Cisco's site as well as the internet. I've originally just set up the basic connection, which worked fine, expecting to just add the appropriate features after having them on site (yeah, I'm a fool to expect that to go rather smoothly). I will be setting up a lab on Monday in order to figure out the pitfalls and bugs without risking cutting myself off the device access ... anyway, due to the limited feature samples I'm not sure whether the intended setup is even technically possible, and what I need to do to get it working ... any help or pointers to appropriate docs is appreciated!
