About
flannel is a virtual networking layer designed specifically for containers. OpenShift Container Platform can use it for networking containers instead of the default software-defined networking (SDN) components. This is useful if running OpenShift Container Platform within a cloud provider platform that also relies on SDN, such as OpenStack, and you want to avoid encapsulating packets twice through both platforms. Each flanneld agent provides this infomation to a centralized etcd store so other agents on hosts can route packets to other containers within the flannel network. The following diagram illustrates the architecture and data flow from one container to another using a flannel network.

About
Tcpdump is a powerful command-line packet analyzer that allows users to display the contents of network packets transmitted or received over a network to which the computer is attached. It operates on most Unix-like systems, including Linux, Solaris, FreeBSD, NetBSD, OpenBSD, and macOS, utilizing the libpcap library for network traffic capture. Tcpdump can read packets from a network interface card or from a previously created saved packet file, and it provides options to write packets to standard output or a file. Users can apply BPF-based filters to limit the number of packets processed, enhancing usability on networks with high traffic volumes. The tool is distributed under the BSD license, making it free software. In many operating systems tcpdump is available as a native package or port, which simplifies installation of updates and long-term maintenance.
