How to analyze the difference between 224.0.0.5 and 224.0.0.6 addresses in OSPF

In this issue, Xiaobian will bring you about how to analyze the specific differences between the two addresses 224.0.0.5 and 224.0.0.6 in OSPF. The article is rich in content and analyzes and narrates from a professional perspective. After reading this article, I hope you can gain something.

224.0.0.6 A multicast receive address for DR and BDR in a multi-access network.

224.0.0.5 This means that all interfaces running OSPF processes on any network belong to this group and thus receive all multicast packets of 224.0.0.5.

Focus on understanding what kind of multicast packets belong to and receive.

For example, DR/BDR belongs to the group with multicast address 224.0.0.6, so it receives multicast packets with destination address 224.0.0.6. It can also be understood why multi-channel access can prevent excessive information processing by setting DR/BDR (because receivers belonging to a certain group (referring to OSPF interface) will only be stripped to Layer 2 without further processing, thus saving a lot of resource waste).

The above is how to analyze the specific difference between the two addresses 224.0.0.5 and 224.0.0.6 in OSPF shared by Xiaobian.
