View
OSPF Area view
Parameter
simple: Uses simple text authentication mode.
md5: Uses MD5 cipher text authentication mode.
Description
Use the authentication-mode command to configure one area of OSPF to support
the authentication attribute.
Use the undo authentication-mode command to cancel the authentication attribute
of this area.
By default, an area does not support authentication attribute.
All the routers in one area must use the same authentication mode (no authentication,
simple text authentication, or MD5 cipher text authentication). If the mode of
supporting authentication is configured, all routers on the same segment must use the
same authentication key.
Use the ospf authentication-mode simple command to configure a simple text
authentication key.
Use the ospf authentication-mode md5 command to configure the MD5 cipher text
authentication key if the area is configured to support MD5 cipher text authentication
mode.
Related command: ospf authentication-mode.
