Switch 7700 Command reference Guide, v2.0

132 CHAPTER 5: USING ROUTING PROTOCOL COMMANDS
After the summarization of imported routes is configured, if the local router is an
autonomous system border router (ASBR), this command summarizes the
imported Type-5 LSAs in the summary address range. When NSSA is configured,
this command will also summarize the imported Type-7 LSAs in the summary
address range.
If the local router acts as both an ABR and a router in the NSSA, this command
summarizes Type-5 LSAs transformed from Type-7 LSAs. If the router is not the
router in the NSSA, the summarization is disabled.
Related commands: display ospf asbr-summary.
Example
To summarize the OSPF imported routes, enter the following:
[SW7700-ospf]asbr-summary 10.2.0.0 255.255.0.0 not-advertise
authentication-mode Syntax
authentication-mode [ simple | md5 ]
undo authentication-mode
View
OSPF Area view
Parameter
simple: Enter to configure simple text authentication mode.
md5: Enter to configure MD5 cipher text authentication mode.
Description
Using the authentication-mode command, you can configure an OSPF area to a
specified authentication mode.
Using the undo authentication-mode command, you can cancel the
authentication mode for this area. By default, an area does not support an
authentication mode.
All the routers in one area must use the same authentication mode (no
authentication, simple text authentication or MD5 cipher text authentication). In
addition, all routers on the same segment must use the same authentication key.
To configure a simple text authentication key, use the ospf
authentication-mode simple
command.
To configure an MD5 cipher text key, use the ospf authentication-mode md5
command.
Related command: ospf authentication-mode.
