IP routing is a very important aspect of a LIS configuration.
This subsection describes how you can ensure end to end
connectivity for a CIP environment.

Generally, for proper CIP routing, an IP route pointing to the
remote access router must exist in your AST710's 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
AST710's 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 AST710's
"
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 AST710 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.
