Configuring the OSPF Area to Support Packet Authentication
All the routers in an area must use the same authentication mode. In addition, all
routers on the same segment must use the same authentication key password. Use
the
authentication-mode simple
password for the area, and the
the MD5 authentication password.
Perform the following configuration in OSPF Area View.
Table 239 Configuring the OSPF Area to Support Packet Authentication
Operation
Configure the area to support
authentication type
Cancel the authentication attribute
of this area
By default, the area does not support packet authentication.
Configuring OSPF Packet Authentication
OSPF supports simple authentication or MD5 authentication between neighboring
routers.
Perform the following configuration in Interface View:
Table 240 Configuring OSPF Packet Authentication
Operation
Specify a password for OSPF simple
text authentication
Cancel simple authentication on the
interface
Specify the key-id and key for OSPF
MD5 authentication
Disable the interface to use MD5
authentication
By default, the interface is not configured with either simple authentication or MD5
authentication.
Configuring OSPF to Import Routes of Other Protocols
The dynamic routing protocols on the router can share routing information. As far as
OSPF is concerned, the routes discovered by other routing protocols are always
processed as the external routes of AS. In the
specify the route cost type, cost value and tag to overwrite the default route receipt
parameters (refer to "Configuring Parameters for OSPF to Import External routes" on
page 249).
The OSPF uses the following four types of routes (in priority):
Intra-area route
■
Inter-area route
■
External route type 1
■
External route type 2
