At the remote DSL side, the CIP LIS is terminated by access
router(2) and IP packets are forwarded to local servers or the
Internet and vice versa.
Here, the CIP member is configured with IP address 172.16.1.2
and is part of the same LIS 172.16.1.x.
Additionally, a VC with the same VPI/VCI values 8/80 is assigned
to this CIP member (e.g. implicit assignment, because AST570(1)
is RFC1577/RFC2225 compliant).
The routing engine must be configured with routes to the final
destinations.
For the given example, the configuration is as follows:
AST570(1) has its default route pointing to access router(2).
The local PCs of IP network 10.0.0.x have default gateways
pointing to AST570(1) .
The access router(2) has a route for Net10" (10.0.0.0)
pointing to AST570(1)
The remote IP network 192.168.0.x has a default gateway
pointing to access router(2).
You will notice that the example relies exclusively on Private IP
addresses. Depending the application though, other IP addresses
in combination with NA(P)T can be used.
See chapter 16 for more information on NA(P)T.
