Configuring Ospf - 3Com 8800 Configuration Manual

3Com Switch 8800 Configuration Guide
Authenticator: OSPF provides clear text authenticator and MD5 encryption
authenticator to authenticate packets transmitted between neighboring routers in
the same area.
Flexible configuration for the router port parameter: On the router port, you can
configure the following OSPF parameters: output cost, Hello packet interval,
retransmission interval, port transmission delay, route precedence, invalid time for
adjacent routers, packet authentication mode, packet authenticator, and others.
Virtual connection: Creates and configures virtual connections.

information, consequently helping users to diagnose failure.

19.2 Configuring OSPF

OSPF configuration needs cooperation among routers: intra-area, area boundary, and
AS boundary. If none of OSPF parameters is configured, their default settings apply. In
this case, sent and received packets are not authenticated, and an individual interface
does not belong to the area of any AS. When reconfiguring a default parameter on one
router, make sure that the same change is made on all other involved routers.
In various configurations, you must first enable OSPF, specify the interface and area ID
before configuring other functions. But the configuration of the functions related to the
interface is not restricted by whether the OSPF is enabled or not. It should be noted that
after OSPF is disabled, the OSPF-related interface parameters also become invalid.
OSPF configuration includes:
1) OSPF basic configuration
Configuring Router ID
Enabling OSPF
Entering the OSPF area view
Enabling OSPF on the specified network
2) Configuration related to OSPF route
Configuring OSPF to import routes of other protocols
Configuring OSPF to import default routes
Configuring OSPF route filtering
Configuring OSPF route convergence
3) Some OSPF configurations
Configuring OSPF precedence
Setting the interface priority for DR election
Configuring OSPF timers
Configuring the time for the interface to send LSUs
Configuring the cost for sending packets on an interface
Configuring cost value for next hop
Configuring the network type on the OSPF interface
Configuring NBMA neighbors for OSPF
