Configuring and Troubleshooting Bay Dial VPN Services

Configuring a Static Route and an Adjacent Host
A static route is a manually configured route that specifies a transmission path that
a packet must follow to another network. For Layer 3 tunnels, you configure a
static route between the CPE router on the remote users home network and the
gateway to restrict the paths that packets follow to the path you specifically
configure.
The network administrator of the remote user’s home network must configure a
static route between the CPE router on the home network and the Dial VPN
gateway to ensure that responses sent to the remote node reach their intended
recipient.
If the CPE router is a Bay Networks router, it must also be configured with the
gateway as an adjacent host. Cisco routers use a different addressing scheme and
therefore do not require that you configure an adjacent host.
Figure 8-1
shows a simplified view of a Layer 3 Dial VPN network connection,
with a static route and an adjacent host configured between the CPE router and the
gateway and another static route configured between the CPE and the remote
node’s supernet.
