+= SRv6-5 node Demo
+
+Requirements::
+
+- docker
+- deb packages for honeycomb (hc2vpp) and vpp
+
+Usage::
+
+. download or build vpp and honeycomb deb packages and place them inside _"../packages"_ folder:
+- honeycomb-*.deb (hc2vpp is required, use _"hc2vpp/packaging/deb/xenial/debuild.sh"_ to build deb package locally)
+- vpp-*.deb
+- vpp-lib*.deb
+- vpp-plugins*.deb
+- you can download vpp packages from
+https://nexus.fd.io/content/repositories/fd.io.master.ubuntu.xenial.main/io/fd/[Nexus Fd.io]
+
+. Run the script _"./create_image.sh"_ in parent directory to create docker image with HC and VPP pre-installed.
+It should be added to docker automatically (a tar file of the image can be created as backup, see content of
+create_image.sh).
+. Start the demo using _"start_demo.sh <demo_type>"_ script where _<demo_type>_ is _"vpp"_ for vpp only setup or _"hc"_
+for setup with honeycomb
+. Clean everything with "clean_demo.sh" script
+. if you need to restart the whole demo use _"restart_demo.sh <demo_type>"_. You don't have to use the same demo type as
+in start_demo script. Current setup will be cleaned and started as a fresh demo.
+
+Topology::
+
+- 5VPP nodes (*vppA* = A::, *vppB* = B::, *vppC* = C::, *vppD* = D::, *vppE* = E::)
+- each node was preassigned with IPv6 addresses on host-veth interfaces (marked red)
+- green dashed line represents how traffic should flow from source to the destination
+- blue dashed line represents return traffic from destination back to source
+
+image::resources/SRv6-5node.svg[SRv6 5node topology]
+
+Testing/debuging::
+
+. to list configuration for all nodes use `./show_configuration.sh` script
+. to test ping for IPv6 use:
+- *hostA:* +
+_sudo ip netns exec VNET_A ping6 E::1_ +
+_sudo ip netns exec VNET_A ping6 E::1 -c 1000 -s 1024 -i 0.0001_ (for bigger flow)
+- *hostE:* +
+_sudo ip netns exec VNET_E ping6 A::1_ +
+_sudo ip netns exec VNET_E ping6 A::1 -c 1000 -s 1024 -i 0.0001_ (for bigger flow)
+
+
+
+. to run packet trace simply use _"pcap_vpp.sh"_ script +
+e.g. ./pcap_vpp.sh <nodeName> <packetCount> +
+_"./pcap_vpp.sh vppA 3"_ +
+
+
+. to observe packet flow use _"watch_int_vpp.sh"_ script +
+e.g. ./watch_int_vpp.sh <nodeName> +
+_"./watch_int_vpp.sh vppA"_
+
+. to check the packet flow on hostE use tcpdump: +
+`sudo ip netns exec VNET_E tcpdump -i vethE -vv -c 4`
+
+Sample packet capture on hostE::
+....
+sudo ip netns exec VNET_E tcpdump -i vethE -vv -c 4
+
+tcpdump: listening on vethE, link-type EN10MB (Ethernet), capture size 262144 bytes
+12:21:00.210165 IP6 (flowlabel 0x3d90e, hlim 62, next-header ICMPv6 (58) payload length: 64) a::1 > e::1: [icmp6 sum ok] ICMP6, echo request, seq 285
+12:21:00.210250 IP6 (flowlabel 0x8fd85, hlim 64, next-header ICMPv6 (58) payload length: 64) e::1 > a::1: [icmp6 sum ok] ICMP6, echo reply, seq 285
+12:21:01.213350 IP6 (flowlabel 0x3d90e, hlim 62, next-header ICMPv6 (58) payload length: 64) a::1 > e::1: [icmp6 sum ok] ICMP6, echo request, seq 286
+12:21:01.213435 IP6 (flowlabel 0x8fd85, hlim 64, next-header ICMPv6 (58) payload length: 64) e::1 > a::1: [icmp6 sum ok] ICMP6, echo reply, seq 286
+4 packets captured
+4 packets received by filter
+0 packets dropped by kernel
+....
+
+Usefull VPP commands::
+
+Note: to use vpp commands for this demo use syntax like this: +
+`"sudo docker exec vppC vppctl sh hardware"`
+
+- vppctl show hardware (show interfaces with L2 addresses)
+- vppctl show int (show interfaces with counters)
+- vppctl show int address (show interfaces with L3 addresses)
+- vppctl show sr localsids (shows local sid table)
+- vppctl show sr policies (list of configured SR policies)
+- vppctl show sr steering-policies (list of configured steering SR policies)
+- vppctl show ip6 fib (shows routing table)
+- vppctl show ip6 fib <dst_ip_mask> (shows routing table and filter matches by destination IP)
