Want this question answered?
Both uses Distance vector algorithm...... . updates the routing table for every 30 seconds. and in OSPF requires hoping reneval of routing table
ospf and static route
OSPF stands for open shortest path first. OSPF is an exterior routing protocol. OSPF uses Path vector routing algorithm.
Dijkstra's algorithm is used by the OSPF and the IS-IS routing protocols. The last three letters in OSPF (SPF) mean "shortest path first", which is an alternative name for Dijkstra's algorithm.
Router R1 is participating in the OSPF routing protocol as well as the EIGRP routing protocol. If R1 learns of network 192.168.10.0/24 from both the OSPF and internal EIGRP routing protocols, how will the route appear in the routing table of R1?
OSPF is short form of open shortest path first. OSPF is based on linked state routing.
There are actually two OSPF and IS-IS
Rip ospf
OSPF is short form of open shortest path first. OSPF is based on linked state routing.
OSPF is a link-state routing protocol.
The first is that the protocol is open, which means that its specification is in the public domain. The OSPF specification is published as Request For Comments (RFC) 1247. The second principal characteristic is that OSPF is based on the SPF algorithm, which sometimes is referred to as the Dijkstra algorithm (Answer is from CCNA 3 guide)
Dijkstra's algorithm has importance when you are trying to find the shortest path between two points. It's used in the computer networking field where routing protocols, like OSPF, uses it to find the shortest path between routers. http://en.wikipedia.org/wiki/Dijkstra%27s_algorithm
