No network is a P2MP network by default, no matter what type of link layer protocol is used on the network. A network can be changed to a P2MP network. The common practice is to change a non-fully meshed NBMA network to a P2MP network. On a P2MP network: Hello packets are transmi...
If the physical status or protocol status of either interface is not up or unstable (an interface flaps, for example), check the physical link and link layer protocol. Ensure that both the physical status and protocol status of each interface are up and that the interfaces have no error pack...
OSPF does not default a network to a P2MP network regardless of the link layer protocol used by the network. A P2MP network must be changed from another network type. It is a typical practice to change non-fully meshed NBMA networks to P2MP networks. ...
Routers that share a segment (Layer 2 link between two interfaces) become neighbors on that segment. OSPF uses the hello protocol as a neighbor discovery and keep alive mechanism. The hello protocol involves receiving and periodically sending hello packets out each interface. The hel...
When the link layer protocol is ATM, Frame Relay, or X.25, the network type is NBMA by default. 4. (Optional.) Set the router priority for the interface ospfv3 dr-priority priority By default, an interface has a router priority of 1. An interface's router priority determines its privil...
December 16, 2024 Chapter: Configure Segment Routing for OSPF Protocol Chapter Contents Open Shortest Path First (OSPF) is an Interior Gateway Protocol (IGP) developed by the OSPF working group of the Internet Engineering Task Force (IETF). Designed expressly for IP ...
l P2MP (point-to-multipoint): by default, OSPF considers no link layer protocol as P2MP, which is a conversion from other network types such as NBMA in general. On P2MP networks, packets are sent to multicast addresses (224.0.0.5). l P2P (point-to-point): when the link layer protoc...
Cumulus Linux uses the administrative distance to choose which routing protocol to use when two different protocols provide route information for the same destination. The smaller the distance, the more reliable the protocol. For example, if the switch receives a route from OSPFv3 with ...

Cisco Meraki layer-3 MS switches support the use of the OSPF routing protocol to advertise its subnets to neighboring OSPF-capable layer 3 devices. This may be desirable in more complex network …
