Operation Manual - Routing Protocol
Quidway S6500 Series Ethernet Switches
The "logic channel" means that the multiple routers running OSPF between two ABRs
only take the role of packet forwarding (the destination addresses of the protocol
packets are not these routers, so these packets are transparent for them and the
routers forward them as common IP packets). The routing information is directly
transmitted between the two ABRs. The routing information herein refers to the type-3
LSAs generated by the ABRs, for which the synchronization mode of the routers in the
area will not be changed.
Perform the following configuration in OSPF Area view.

area-id and router-id have no default value. By default, hello timer is 10 seconds,
retransmit 5 seconds, trans-delay 1 second, and the dead 40 seconds.
4.2.19 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 ospf
authentication-mode simple command. And, 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.
Perform the following configuration in OSPF Area view.
