What is the default priority for OSPF routers?
What is the default priority for OSPF routers?
1
Default priority for an OSPF interface is 1. The range is from 0 to 255. 0 means that the interface does not involve in the DR election. The following command configures a priority value on an interface.
What is default route injection?
Default routes injected into a normal area can be originated by any OSPF router. The OSPF router does not, by default, generate a default route into the OSPF domain. In order for OSPF to generate a default route, you must use the default-information originate command.
Which command is used to inject a default route into an OSPF area?
The use of a route map, map , tells the router to inject the default route if the route map’s conditions are met. For OSPF, this command tells an Autonomous System Border Router (ASBR) to inject a default route into the OSPF domain.
What command would be used to advertise a default static route in OSPF?
redistribute static subnets
Under OSPF process “redistribute static subnets “command is used to redistribute static routes in OSPF, However static default route (ip route 0.0.
How does OSPF set priority value?
Use the ip ospf priority [1 – 255] command to set the priority to a value between 1 and 255. Use the ip ospf priority 0 command to configure the router to never function as the designated router or backup designated router. Use the no ip ospf priority command to set the priority at the default value of 1.
When the OSPF priorities on all the routers are the same How is the DR selected?
When the OSPF priorities on all the routers are the same, how is the DR selected? (D) One is randomly selected.
What is default route used for?
The default route is a route that a router uses to forward an incoming packet when no other route is available for that packet in the routing table. Routers use the routing table to make the forwarding decision.
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.
