OSPF Protocol Configuration
OSPF
(
Open Shortest Path First
) — dynamic routing protocol based on, channels status tracking
technology (link-state technology) which uses Dijkstra algorithm for finding the shortest way. OSPF
protocol is a protocol of internal gateway (IGP). OSPF protocol distributes information about available
routes between routers of one independent system.
OSPF protocol is not supported in the stackable mode.

Table 5.272 - Commands of global configuration mode
Command
Default value
Action
router ospf enable
-
Enables routing via OSPF protocol.
no router ospf enable
Disables routing via OSPF protocol.
router ospf redistribute
{ connected, rip, static }
-
Allows announcing of static routes via OSPF:
-
connected
– of networks announced on the switch;
-
rip
– of routes received via RIP;
-
static
– of static routes.
no router ospf redistribute
{ connected, rip, static
Assigns default value.
router ospf compatible
rfc1583
enabled
Enables compatibility with RFC 1583.
no router ospf compatible
rfc1583
Disables compatibility with RFC 1583.
router ospf router-id
A.B.C.D
-
Assigns router ID which gives the router unique number within
one independent system.
- A.B.C.D – router ID in format of IPv4 address.
no router ospf router-id
Assigns default value.
