Loading

Start the Lab

Run the ./lab_start.sh Then run sh srv6_encaps_ipv4.sh

Access the Lab

Example command to access the R1: docker exec -it R1 bash

if you want to steer IPv6 route, you may try below commands

docker exec -it R1 ip -6 route add fc00:10:10:5::/64 encap seg6 mode encap segs fc00:10:10:10::20,fc00:10:10:30::40,fc00:10:10:50::50 dev eth1
docker exec -it R5 ip -6 route add fc00:10:10:1::/64 encap seg6 mode encap segs fc00:10:10:50::40,fc00:10:10:30::20,fc00:10:10:10::10 dev eth2

if you want to steer IPv4 route, you may try below commands

docker exec -it R1 ip -4 route add 10.10.5.0/24 encap seg6 mode encap segs fc00:10:10:5:: dev eth0
docker exec -it R5 ip -4 route add 10.10.1.0/24 encap seg6 mode encap segs fc00:10:10:1:: dev eth0

if you would like to capture the traffic on a some segment you may refer to the below command, just change the example R1R2 example.

of course, you need to install tshark on your Linux.

sudo tshark -i dm-$(docker network ls | grep -i R1R2 | cut -d ' ' -f1) -Y icmpv6 -V |grep -i source

Stop the Lab

Run the ./lab_stop.sh

You can refer to example commands in the srv6_encaps_ipv4.sh
