sudo ip link set dev vpp1host up
sudo ip addr add 10.10.1.1/24 dev vpp1host
sudo ip -6 addr add 2001:f1::1/126 dev vpp1host

sudo ip link add name vpp2out type veth peer name vpp2host
sudo ip link set dev vpp2out up
sudo ip link set dev vpp2host up
sudo ip addr add 10.11.4.1/24 dev vpp2host
sudo ip -6 addr add 2001:f4::1/126 dev vpp2host

sudo ip route add 10.10.2.0/24 via 10.10.1.2

4 terminals should be open

Multiple terminals can be launched using tmux. See the script tmux-launch.sh

Terminal 1: Running encap node

cd <vpp-repository>
export STARTUP_CONF=/<this_repository>/dev_srh_export/1_vpp.conf
make run

Terminal 2: Running transit node

cd <vpp-repository>
export STARTUP_CONF=/<this_repository>/dev_srh_export/2_vpp.conf
make run

Terminal 3: Running decap node

cd <vpp-repository>
export STARTUP_CONF=/<this_repository>/dev_srh_export/3_vpp.conf
make run

Terminal 4: Sending packets

sudo python3 ./sender-udp.py
