Keywords and
variables Description Default Availability
authentication
{md5 | none | text}
Set the authentication type.
Use the
authentication
keyword to
define the authentication used for OSPF
packets sent and received in this area. If
you select
none
, no authentication is
used. If you select
text
, the
authentication key is sent as plain text. If
you select
md5
, an authentication key is
used to generate an MD5 hash.
Both text mode and MD5 mode only
guarantee the authenticity of the OSPF
packet, not the confidentiality of the
information in the packet.
In text mode the key is sent in clear text
over the network. Text mode is usually
used only to prevent network problems
that can occur if an unwanted or
misconfigured router is mistakenly
added to the area.
If you configure authentication for
interfaces, the authentication configured
for the area is not used. Authentication
passwords or keys are defined per
interface. See “config ospf-interface” on
page 180 .
