7 # This test is designed for evaluating the new SRv6 End.DT46 Behavior used for
8 # implementing IPv4/IPv6 L3 VPN use cases.
9 #
10 # The current SRv6 code in the Linux kernel only implements SRv6 End.DT4 and
11 # End.DT6 Behaviors which can be used respectively to support IPv4-in-IPv6 and
12 # IPv6-in-IPv6 VPNs. With End.DT4 and End.DT6 it is not possible to create a
13 # single SRv6 VPN tunnel to carry both IPv4 and IPv6 traffic.
14 # The SRv6 End.DT46 Behavior implementation is meant to support the
15 # decapsulation of IPv4 and IPv6 traffic coming from a single SRv6 tunnel.
16 # Therefore, the SRv6 End.DT46 Behavior in the Linux kernel greatly simplifies
17 # the setup and operations of SRv6 VPNs.
18 #
19 # Hereafter a network diagram is shown, where two different tenants (named 100
20 # and 200) offer IPv4/IPv6 L3 VPN services allowing hosts to communicate with
21 # each other across an IPv6 network.
22 #
23 # Only hosts belonging to the same tenant (and to the same VPN) can communicate
24 # with each other. Instead, the communication among hosts of different tenants
25 # is forbidden.
26 # In other words, hosts hs-t100-1 and hs-t100-2 are connected through the
27 # IPv4/IPv6 L3 VPN of tenant 100 while hs-t200-3 and hs-t200-4 are connected
28 # using the IPv4/IPv6 L3 VPN of tenant 200. Cross connection between tenant 100
29 # and tenant 200 is forbidden and thus, for example, hs-t100-1 cannot reach
30 # hs-t200-3 and vice versa.
31 #
32 # Routers rt-1 and rt-2 implement IPv4/IPv6 L3 VPN services leveraging the SRv6
33 # architecture. The key components for such VPNs are: a) SRv6 Encap behavior,
34 # b) SRv6 End.DT46 Behavior and c) VRF.
35 #
36 # To explain how an IPv4/IPv6 L3 VPN based on SRv6 works, let us briefly
37 # consider an example where, within the same domain of tenant 100, the host
38 # hs-t100-1 pings the host hs-t100-2.
39 #
40 # First of all, L2 reachability of the host hs-t100-2 is taken into account by
41 # the router rt-1 which acts as a arp/ndp proxy.
42 #
43 # When the host hs-t100-1 sends an IPv6 or IPv4 packet destined to hs-t100-2,
44 # the router rt-1 receives the packet on the internal veth-t100 interface. Such
45 # interface is enslaved to the VRF vrf-100 whose associated table contains the
46 # SRv6 Encap route for encapsulating any IPv6 or IPv4 packet in a IPv6 plus the
47 # Segment Routing Header (SRH) packet. This packet is sent through the (IPv6)
48 # core network up to the router rt-2 that receives it on veth0 interface.
49 #
50 # The rt-2 router uses the 'localsid' routing table to process incoming
51 # IPv6+SRH packets which belong to the VPN of the tenant 100. For each of these
52 # packets, the SRv6 End.DT46 Behavior removes the outer IPv6+SRH headers and
53 # performs the lookup on the vrf-100 table using the destination address of
54 # the decapsulated IPv6 or IPv4 packet. Afterwards, the packet is sent to the
55 # host hs-t100-2 through the veth-t100 interface.
56 #
57 # The ping response follows the same processing but this time the roles of rt-1
58 # and rt-2 are swapped.
59 #
60 # Of course, the IPv4/IPv6 L3 VPN for tenant 200 works exactly as the IPv4/IPv6
61 # L3 VPN for tenant 100. In this case, only hosts hs-t200-3 and hs-t200-4 are
62 # able to connect with each other.
