12.2.6 Adding Appropriate Routes to the Routing Tables
IP routing is a very important aspect for a LIS configuration.
This subsection describes how you can ensure endtoend
connectivity for a CIP environment.

Generally, for proper CIP routing, an IP route pointing to the
remote access router must exist in your AST570 ' IP routing table.
If the remote access router is RFC1577/RFC2225 compliant, no
routes for LIS connectivity need to be configured by yourself for the
AST570 ' IP router. This because it automatically adds two
necessary routes as soon you configure the CIP member, i.e. two
default gateways, thus
any
(0.0.0.0/0) as source address, and
with:
The LIS's local CIP member's IP address, i.e. the AST570 ' CIP
interface address as destination
and
The LIS's IP subnetwork (based on the CIP member's IP
parameters) as destination.
As the RFC1577/RFC2225 compliant remote access router, falls
within the same LIS as the AST570 CIP member, it is also a
member of the second route's destination IP subnetwork.
If the remote access router is not RFC1577/RFC2225 compliant,
you must add this default route (with the known remote IP
address) yourself.
