WM Access Domain Services Configuration
To define a next hop route and OSPF advertisement:
1 From the main menu, click WM-AD Configuration. The WM-AD Configuration screen is
displayed.
2 In the left pane WM Access Domains list, click the WM-AD you want to define a next-hop route for.
The Topology tab is displayed.
3 In the Next Hop Address box, type the IP address of the next hop router on the network through
which you wish all traffic on this WM-AD to be directed.
4 In the OSPF Route Cost box, type the OSPF cost of reaching the WM-AD subnet.
The OSPF cost value provides a relative cost indication to allow upstream routers to calculate
whether or not to use the controller as a better fit or lowest cost path to reach devices in a particular
network. The higher the cost, the less likely of the possibility that the controller will be chosen as a
route for traffic, unless that controller is the only possible route for that traffic.
5 To disable OSPF advertisement on this WM-AD, select the disable OSPF Advertisement checkbox.
Defining the IP Address for the WM-AD (for the DHCP Server on the Controller)
Bridged at the AP WM-ADs do not require the definition of a corresponding IP address definition for
the WM-AD since all traffic for users in that WM-AD will be directly bridged by the AP at the local
network point of attachment (VLAN at AP port).
The IP address definition is only required for a routed WM-AD or VLAN bridged WM-AD.
To define the IP address for the WM-AD:
1 From the main menu, click WM-AD Configuration. The WM-AD Configuration screen is
displayed.
2 In the left pane WM Access Domains list, click the WM-AD you want to define the IP address for.
The Topology tab is displayed.
3 In the Gateway box, type the Summit WM Controller's own IP address in that WM-AD.
This IP address is the default gateway for the WM-AD. The Summit WM Controller advertises this
address to the wireless devices when they sign on. For routed WM-ADs, it corresponds to the IP
address that is communicated to MUs (in the WM-AD) as the default gateway for the WM-AD
subnet. (MUs target the Summit WM Controller's interface in their effort to route packets to an
external host).
For a VLAN bridged WM-AD, the IP address corresponds to the Summit WM Controller's own
point of presence on the VLAN. In this case, the controller's interface is typically not the gateway for
the subnet. The gateway for the subnet is the infrastructure router defined to handle the VLAN.
NOTE
If you are configuring Bridged at Controller WM-AD, the Gateway field appears as Interface IP Addr on the user
interface.
4 In the Mask box, type the appropriate subnet mask for this IP address to separate the network
portion from the host portion of the address (typically 255.255.255.0).
The following values to DHCP configuration are only applicable for configurations if the controller is
the DHCP server for users in the WM-AD—a routed WM-AD or a VLAN bridged WM-AD with
