Requirements Outside the Dial VPN Network

• Specify the subnet mask of the next hop router. (Required)
• Specify a weighted value (with 16 being the most preferred) that the IP router
uses to select a route when its routing tables contain multiple routes to the
same destination. The default is 16.
• Specify the name of the circuit on the local router associated with the static
route over an unnumbered interface. (Required only for unnumbered
interfaces.)
Configuring the CPE Frame Relay Circuit with Site Manager
If the CPE is a BayStream platform, refer to the BayStream manual, Configuring
Frame Relay Services for IP Routing for details on configuring frame relay on an
interface using Site Manager. Otherwise, refer to the frame relay documentation
appropriate to the CPE router on the home network for detailed frame relay
configuration information.
The rest of this chapter describes the most important Dial VPN considerations in
configuring the frame relay parameters.
• If you are using Site Manager, you can accept the default values for most
frame relay parameters. Do not change the Service Name parameter value that
the router assigns.
• Put all frame relay PVCs running virtual private network services (that is,
Dial VPN) in one service record. Do not mix them with other (routed) PVCs
in the same service record. See the frame relay documentation for a
description of service records and their use.
• If you use the default service record for Dial VPN PVCs, you do not need to
configure the PVCs, because the gateway learns the DLCIs dynamically
through the Local Management Interface (LMI) protocol. If you are not using
the default service record for the Dial VPN PVCs, you must manually
configure the PVCs to a specific service record.
• You must configure two static routes from the CPE router: one to the
RADIUS client on the gateway and one to the remote node’s “supernet” that
services all the remote nodes in the same user community. In addition, for Bay
Networks routers, you must configure an adjacent host as the next hop for the
return messages.
