OSPF is mostly a link-state routing protocol. OSPF version 2 is a routing protocol which is described in RFC 2328OSPF is an IGPCompared with RIP OSPF can provide scalable network support and faster convergence times.

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. 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. Send only site-to-site traffic meaning that if a subnet is at a remote site the traffic destined for that subnet is sent over the VPNHowever if traffic is destined for a network that is not in the VPN mesh for example traffic going to a public web.

In IPv4 the CIDR notation is 00000 whereas in IPv6 it is 0. A routing table entry consists of two pieces. When a default route on the network is generated by another routing process not OSPF process the device that generates the default route must advertise the default route in the entire OSPF AS.

In contrast to distance. OSPF is widely used in large networks such as ISP backbone and enterprise networks. The remote network and the local interface that is connected to that network.

The command above instructs R1 to match all IP address and subnet masks and send the packets to 10002 the interface on R3 that is connected to R1. In OSPF the default-information originate command will not advertise to any other routers without a default. By default devices in a common OSPF area do not automatically generate default routes even if the common OSPF area has default routes.

Split tunnel no default route. R1configip route 0000 0000 10002. The default route on R2 comes up again and R2 can reach 1001001001 again.

And because the prefix length is 0 it is also the shortest possible match. The routing table on R1 now looks like this. To create a default static route on R1 we need to use the following command.

There are two tunneling modes available for MX-Z devices configured as a Spoke.
