What does the default-information originate in OSPF?

Configures OSPF to advertise the default route (0.0. 0.0/0) to its neighbors, regardless if it is present in the routing table or not. The no form of this command sets the OSPF administrative distance to the default of 110.

Where does default-information originate?

Configuring default-information originate on the middle router’s RIP process tells RIP to distribute a default route out the interfaces on which it is enabled to all other RIP-speaking routers.

How do I set the default route in OSPF?

Discussion. Unlike RIP and EIGRP, you cannot create a default route in OSPF by simply redistributing a static route. Even if there is a default route in the routing table, by default Cisco’s OSPF implementation will not forward it to the rest of the network.

What is default originate in BGP?

• default-information originate causes the default route to be artificially generated and. injected into the BGP RIB, regardlessly of whether it is present in the routing table.

What is OSPF default metric?

By default, OSPF assigns a default cost metric of 1 to any link faster than 100 Mbps, and a default cost metric of 0 to the loopback interface (lo0). No bandwidth is associated with the loopback interface. This means that all interfaces faster than 100 Mbps have the same default cost metric of 1.

What does default-information originate always do?

In OSPF, the “default-information originate” command will not advertise to any other routers without a default route in the routing table. When added the “always” keyword , it tells the router to advertise a default route to other routers even if you don’t have a default route in the routing table.

What is default-information originate command do?

The ‘default-information originate’ command is required for OSPF to generate a default route. In our example above, router R1 is directly connected to the Internet. It’s a common enterprise setup where all Internet traffic breaks out from a single site.

How does default route work?

A default route is the route that takes effect when no other route is available for an IP destination address. If a packet is received on a routing device, the device first checks to see if the IP destination address is on one of the device’s local subnets.

  • When to use OSPF?

    Router I’d – It is the highest active IP address present on the router.

  • Router priority – It is an 8-bit value assigned to a router operating OSPF,used to elect DR and BDR in a broadcast network.
  • Designated Router (DR) – It is elected to minimize the number of adjacencies formed.
