VPP L2 Bridge Forwarding

In this experiment, VPP is used to take over two network cards to form a bridge, and the two computers connected to the bridge can communicate with each other.

environment

Ubuntu version: 20.04

VPP version: 23.02

topology

configuration

virtual network

Create new VMnet2 and VMnet3 to isolate the two PCs

 Ubuntu (the machine where VPP runs)

Create two network cards and put them in VMnet2 and VMnet3 respectively

Two Win10 virtual machines

Each has a network card, respectively placed in VMnet2 and VMnet3
