Lab 3.2 v09.05 switch to Cilium from Calico - no tun interfaces

Hi! Couple questions...
Did the labs moved from Calico to Cilium in this most recent v09.05? There still seem to be many references to Calico in the labs.
On Lab 3.4 part 19 should I be doing the following since tun10 might be Calico?
sudo tcpdump -i cilium_host
Thanks!

Hello @scott.sorell
Yes, the labs are now using cilium as CNI.
Calico uses tunl0 is an IPIP tunnel for encapsulating pod traffic. We will update the labs to remove the Calico and tunl0 reference from the lab section.
You can use sudo tcpdump -i cilium_host or sudo tcpdump -i cilium_vxlan as well.
thank you

OR, it seems I get http responses on cilium_vxlan network

Thanks! Good to know. Just a suggestion... it might be good to include a short changelog of what switched between old and new labs in the announcement for v09.05.
