4.2.20 Configuring OSPF Packet Authentication
OSPF supports simple authentication or MD5 authentication between neighboring
routers.
Perform the following configuration in Interface view:
Table 4-20 Configuring OSPF Packet Authentication
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.
4.2.21 Configure OSPF to import Routes of Other Protocols
The dynamic routing protocols on the router can share the 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 import-route commands, you can
specify the route cost type, cost value and tag to overwrite the default route receipt
parameters (refer to "Configure Parameters for OSPF to import External Routes").
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
Intra-area and inter-area routes describe the internal AS topology whereas the external
routes describe how to select the route to the destinations beyond the AS.
The external routes type-1 refer to the imported IGP routes (such as static route and
RIP). Since these routes are more reliable, the calculated cost of the external routes is
the same as the cost of routes within the AS. Also, such route cost and the route cost of
the OSPF itself are comparable. That is, cost to reach the external route type 1 = cost to
