Inter-Area OSPF

117237-E Rev.00
Intra-Area OSPF allows OSPF to run within a single area. By
enabling OSPF and disabling RIP, the router is configured to the
default settings that are suitable for standard Intra-Area OSPF
operation.
The configuration can be optimized by adjusting the OSPF
parameters available on the relevant OSPF path
The default area for Intra-Area networking is Area 0.
Warning: While Nautica routers support the concurrent
operation of RIP and OSPF, they do not support the exchange of
routing information between the two protocols.
Inter-Area OSPF allows different areas within a large autonomous
network to communicate with each other. It also allows more
efficient distribution of routing information (such as routing
tables) between networks.
OSPF is set-up primarily on the paths that interface the ABRs to
the various areas. An ABR has at least two OSPF paths (in
addition to LAN01), one that links it to Area 0, and one that links
it to another area.
