In the command output, the Immediate Reason field indicates the direct cause for neighbor down, and the Primary Reason field indicates the root cause for neighbor down. You can determine the cause of OSPF neighbor flapping according to the two fields. <HUAWEI> display ospf peer last-...
Virtual network device (vnet): A virtual network device is plumbed into the guest domain. It is analogous to a physical network device in a non-virtualized environment, where you plug one end of the cable into the network port and the other end of that cable into a switch. In the v...
If you’re using the ifupdown plugin (for example, in Ubuntu and Debian), add the interface configuration to your /etc/network/interfaces file and then set the value of managed to false in the ifupdown section of the NetworkManager.conf file: 您可以通过使用插件告诉NetworkManager忽略某个接口。
If you’re lucky, you’ll only deal with easy subnet masks like 255.255.255.0 or 255.255.0.0, but you may be unfortunate and encounter stuff like 255.255.255.192, where it isn’t quite so simple to determine the set of addresses that belong to the subnet. Furthermore, it’s likely that...

Path MTU Discovery (PMTUD) is used to determine the path MTU between two devices. Path MTU Discovery is especially important if the client or target does not support jumbo frames. When a host sends a packet that is larger than the MTU of the receiving host or larger than the MTU of a ...
Neighbor Advertisement messages contain information that nodes require to determine the type of Neighbor Advertisement message, the link-layer address of the sender, and the sender’s role on the network. Redirect IPv6 routers send Redirect messages to inform an originating host of a better first-...
