Configuring Ospf Authentication - 3Com 8800 Configuration Manual

3Com Switch 8800 Configuration Guide
By default, all interfaces are allowed to transmit and receive OSPF packets.
After an OSPF interface is set to be in silent status, the interface can still advertise its
direct route. However, the OSPF hello packets of the interface will be blocked, and no
neighboring relationship can be established on the interface. Thereby, the capability for
OSPF to adapt to the networking can be enhanced, which will hence reduce the
consumption of system resources. On a switch, this command can disable/enable the
specified VLAN interface to send OSPF packets.

19.2.19 Configuring OSPF Authentication

I. Configuring the OSPF Area to Support Packet Authentication
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. To configure a simple text authentication key, use the
authentication-mode simple command. Use the authentication-mode md5
command to configure the MD5 cipher text authentication key if the area is configured
to support MD5 cipher text authentication mode.
Perform the following configuration in OSPF area view.

By default, the area does not support packet authentication.
II. Configuring OSPF packet authentication
OSPF supports simple authentication or MD5 authentication between neighboring
routers.
Perform the following configuration in interface view.
