Which command is used to propagate a default route in ospfv2?
To propagate a default route, the edge router (R2) must be configured with: A default static route using the ip route 0.0. 0.0 0.0. 0.0 {ip-address | exit-intf} command.
How do you propagate a default route?
Default Route Propagation
- Using static default route (ip route 0.0.0.0 0.0.0.0 next_hop) then redistributing it for propagation (redistribute static)
- Using the ip default-network x.x.x.x. This command by itself will propagate the network specified as an argument in the command with some exceptions.
Which are ip command is used to propagate a default route?
To view the default route configuration, use the “show ip route” command from the privileged-exec mode. You can also use the “show running-config” command to view the command that was used to configure the default route.
How do I propagate a default route in EIGRP?
One way to inject a default route into EIGRP is to configure a static default route pointing to Null0 and then redistribute the default route into EIGRP. When redistributing a static, connected, or EIGRP route for another AS, the metric does not need to be assigned. The default route will be an external EIGRP route.
What is default route OSPF?
The default route or the Gateway of Last Resort is used to forward packets if our destination IP address does not have a match in our routing table. In IPv4, the CIDR notation is 0.0. 0.0/0, whereas, in IPv6, it is ::/0.
What is default route propagation OSPF?
If a default route is already in present in routing table, such as via static or dynamic protocol, OSPF originate default route. If default route does not exist in routing table, OSPF will not originate default route. This behavior is desirable when there are multiple exist point out of OSPF domain to external network.
How do I set a default route on a Cisco router?
Perform these steps to configure a default route.
- Enter global configuration mode. device# configure terminal.
- Enter 0.0. 0.0 0.0.
- (Optional) Enable the default network route for static route next-hop resolution.
- (Optional) Configure next-hop recursive lookup to resolve the next-hop gateway.
Which is the default route in a routing table?
The default route is generally the address of another router, which treats the packet the same way: if a route matches, the packet is forwarded accordingly, otherwise the packet is forwarded to the default route of that router.
How do you set a default route in Linux?

How do I configure OSPF to propagate the default route?
Configure R2 with a directly attached default route to the Internet. Step 2: Propagate the route in OSPF. Configure OSPF to propagate the default route in OSPF routing updates. Step 3: Examine the routing tables on R1 and R3.
How to verify that the default route is being propagated correctly?
Verify that the default route is being propagated correctly by viewing the routing table on R4. Objective 1. – Configure R1 to always originate a default route through out the entire OSPF autonomous system. R1# configure terminal Enter configuration commands, one per line.
What is the difference between Rip and OSPF router configuration?
In RIP you use the default-information originate command in RIP router configuration mode and this will advertise a default route through out the RIP domain. However if you issue this command in OSPF router configuration mode this will advertise a default route from the router as a type 5 LSA in a normal area (Non-Backbone/Non Stub Area).
Why won’t this command advertise a default route?
This command will not advertise a default route unless a static default route exist on the router you’ve issued this command on.
