How to use

• Copy the files to their crosponding nodes.
  • 10-rust_bridge-master.conf
  • 10-rust_bridge-node01.conf
  • 10-rust_bridge-node02.conf
• Build the rust code using cargo build.
• Copy the binary using the following command cp ./target/debug/cni-bridge /opt/cni/bin/.

  • setup_node01.sh
  • setup_node02.sh
