| # This test is designed for evaluating the new SRv6 End.DT46 Behavior used for |
| # implementing IPv4/IPv6 L3 VPN use cases. |
| # |
| # The current SRv6 code in the Linux kernel only implements SRv6 End.DT4 and |
| # End.DT6 Behaviors which can be used respectively to support IPv4-in-IPv6 and |
| # IPv6-in-IPv6 VPNs. With End.DT4 and End.DT6 it is not possible to create a |
| # single SRv6 VPN tunnel to carry both IPv4 and IPv6 traffic. |
| # The SRv6 End.DT46 Behavior implementation is meant to support the |
| # decapsulation of IPv4 and IPv6 traffic coming from a single SRv6 tunnel. |
| # Therefore, the SRv6 End.DT46 Behavior in the Linux kernel greatly simplifies |
| # the setup and operations of SRv6 VPNs. |
| # |
| # Hereafter a network diagram is shown, where two different tenants (named 100 |
| # and 200) offer IPv4/IPv6 L3 VPN services allowing hosts to communicate with |
| # each other across an IPv6 network. |
| # |
| # Only hosts belonging to the same tenant (and to the same VPN) can communicate |
| # with each other. Instead, the communication among hosts of different tenants |
| # is forbidden. |
| # In other words, hosts hs-t100-1 and hs-t100-2 are connected through the |
| # IPv4/IPv6 L3 VPN of tenant 100 while hs-t200-3 and hs-t200-4 are connected |
| # using the IPv4/IPv6 L3 VPN of tenant 200. Cross connection between tenant 100 |
| # and tenant 200 is forbidden and thus, for example, hs-t100-1 cannot reach |
| # hs-t200-3 and vice versa. |
| # |
| # Routers rt-1 and rt-2 implement IPv4/IPv6 L3 VPN services leveraging the SRv6 |
| # architecture. The key components for such VPNs are: a) SRv6 Encap behavior, |
| # b) SRv6 End.DT46 Behavior and c) VRF. |
| # |
| # To explain how an IPv4/IPv6 L3 VPN based on SRv6 works, let us briefly |
| # consider an example where, within the same domain of tenant 100, the host |
| # hs-t100-1 pings the host hs-t100-2. |
| # |
| # First of all, L2 reachability of the host hs-t100-2 is taken into account by |
| # the router rt-1 which acts as a arp/ndp proxy. |
| # |
| # When the host hs-t100-1 sends an IPv6 or IPv4 packet destined to hs-t100-2, |
| # the router rt-1 receives the packet on the internal veth-t100 interface. Such |
| # interface is enslaved to the VRF vrf-100 whose associated table contains the |
| # SRv6 Encap route for encapsulating any IPv6 or IPv4 packet in a IPv6 plus the |
| # Segment Routing Header (SRH) packet. This packet is sent through the (IPv6) |
| # core network up to the router rt-2 that receives it on veth0 interface. |
| # |
| # The rt-2 router uses the 'localsid' routing table to process incoming |
| # IPv6+SRH packets which belong to the VPN of the tenant 100. For each of these |
| # packets, the SRv6 End.DT46 Behavior removes the outer IPv6+SRH headers and |
| # performs the lookup on the vrf-100 table using the destination address of |
| # the decapsulated IPv6 or IPv4 packet. Afterwards, the packet is sent to the |
| # host hs-t100-2 through the veth-t100 interface. |
| # |
| # The ping response follows the same processing but this time the roles of rt-1 |
| # and rt-2 are swapped. |
| # |
| # Of course, the IPv4/IPv6 L3 VPN for tenant 200 works exactly as the IPv4/IPv6 |
| # L3 VPN for tenant 100. In this case, only hosts hs-t200-3 and hs-t200-4 are |
| # able to connect with each other. |
