Deploy SRH topology

Install

git clone https://gerrit.fd.io/r/vpp
cd vpp

git remote add insa git@github.com:insa-unyte/vpp-srh-export.git
git fetch insa
git checkout feature/ipfix-onpath-telemetry

make build

Topology

See topology

Policy

There is a SR tunnel between the first node and the last node. In the SRv6 packet, the IOAM trace option is included in the hop-by-hop option.

Run

Create virtual interfaces on the server:

sudo ip link add name vpp1out type veth peer name vpp1host
sudo ip link set dev vpp1out up
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
sudo ip route add 2001:f2::0/126 via 2001:f1::2
sudo ip route add 10.10.3.0/24 via 10.10.1.2
sudo ip route add 2001:f3::0/126 via 2001:f1::2

sudo ip route add 2001:f4::1/126 via 2001:f1::2

Running vpp nodes

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_jbayaux_ioam/1_vpp.conf
make run

Terminal 2: Running transit node

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

Terminal 3: Running decap node

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

Terminal 4: Sending packets

sudo python3 ./sender-udp.py

Debugging

Checking that the messages are been sent

sudo tcpdump -i vpp2host
