![]() The test creates two netns, ns1 and ns2. The host (the default netns) has an ipip or ip6tnl dev configured for tunneling traffic to the ns2. ping VIPS from ns1 <----> host <--tunnel--> ns2 (VIPs at loopback) The test is to have ns1 pinging VIPs configured at the loopback interface in ns2. The VIPs are 10.10.1.102 and 2401:face::66 (which are configured at lo@ns2). [Note: 0x66 => 102]. At ns1, the VIPs are routed _via_ the host. At the host, bpf programs are installed at the veth to redirect packets from a veth to the ipip/ip6tnl. The test is configured in a way so that both ingress and egress can be tested. At ns2, the ipip/ip6tnl dev is configured with the local and remote address specified. The return path is routed to the dev ipip/ip6tnl. During egress test, the host also locally tests pinging the VIPs to ensure that bpf_redirect at egress also works for the direct egress (i.e. not forwarding from dev ve1 to ve2).
