OSPF Features
The switches support the following OSPF features:
z Stub area: Stub area is defined to reduce the cost for the routers in the area to receive ASE routes.
z NSSA: NSSA is defined to remove the limit on the topology in a Stub area.
z OSPF multi-process: Multiple OSPF processes can be run on a router.
z Sharing discovered routing information with other dynamic routing protocols: At present, OSPF
supports importing the routes of other dynamic routing protocols (such as RIP), and static routes as
OSPF external routes into the AS to which the router belongs. In addition, OSPF supports
advertising the routing information it discovered to other routing protocols.
z Packet authentication: OSPF supports the authentication of the packets between neighboring
routers in the same area by using one of the two methods: plain text authentication and MD5
authentication.
z Flexible configuration of router interface parameters: For a router interface, you can configure the
following OSPF parameters: output cost, Hello interval, retransmission interval, interface
transmission delay, route priority, dead time for a neighboring router, and packet authentication
mode and authentication key.
z Virtual link: Virtual links can be configured.
