QuickSET Configuration Guide
* If the router is not configured to authenticate RIP-2 messages, then RIP-1 and unauthenticated
RIP-2 messages will be accepted. Authenticated RIP-2 messages will be discarded. If the router is
configured to authenticate RIP-2 messages, then RIP-1 messages and RIP-2 messages which pass
authentication testing will be accepted. Unauthenticated and failed authentication RIP-2 messages
shall be discarded.
OSPF Settings
The OSPF Settings window shown in
Figure 140
, on the following page, displays after clicking on
the OSPF Settings button in the Advanced Routing Configuration window. OSPF
OSPF (Open Shortest Path First) is a Link-State Protocol. OSPF distributes routing information
between routers belonging to a single Autonomous System (AS). In an Autonomous System,
routers exchange routing information through a common routing protocol.
An Autonomous System may contain one or more networks, but each network within the AS may
or may not support subnetting. Every OSPF routing domain must have a “Backbone”. An OSPF
backbone distributes routing information between areas in an OSPF routing domain. The
backbone of an OSPF routing domain is an OSPF area possessing an area ID of 0.0.0.0.
Because OSPF Protocol only broadcasts link state updates when the topology has changed, it is
considered “quiet” when compared to RIP Protocol, which has to periodically send a portion, or all
of its routing table to its neighbors.
Convergence (the time it takes to recalculate routing tables) under the OSPF Protocol is
instantaneous and not periodic because of the use of IP Multicast to send the link-state updates.
Updates are only sent when routing changes occur instead of periodically, ensuring better use of
available bandwidth.
