It consists of two tasks: +; 1) ipv6_encap that encapsulates IPv4 packets into IPv6 and sends those tunnel +; packets towards the customer tunnel endpoint. For this, it must use a +; binding table that associates with each tunnel, a public IPv4 address and a +; set of ports. +; 2) ipv6_decap which handles packets arriving from the tunnel, checks they use +; a source IPv4 address and port combination that matches their originating +; tunnel (based on the same binding table as used by ipv6_encap), removes the +; IPv6 encapsulation and sends them out its "internet" interface. +; The binding table must be loaded in the [lua] section and assigned to the +; tasks using the "tun_bindings" parameter. This configuration loads its binding +; table from the provided ip6_tun_bind.lua but other binding tables can be used. +; +; Binding tables of different sizes and different ranges of addresses and ports +; can be generated by a provided helper script: +; helper-scripts/ipv6_tun/ipv6_tun_bindings.pl -n <num_entries> +; Most other parameters of the generated binding table can be tweaked through +; script command-line switches. For more details, refer to the documentation of +; the script obtained by running it with -help as argument. +; The same script can also generate tables for testing tools to generate packets +; with addresses and ports that match entries from the binding table (randomly +; selecting entries from the binding table). +; Additionally, the helper-scripts/ipv6_tun/gen_4over6.pl script can be used to +; generate pcap files with IPv6 (tunnel) and IPv4 (internet) traffic matching a +; given binding table. +; Example usage: +; ./helper-scripts/ipv6_tun/ipv6_tun_bindings.pl -n 100000 -suffix _100k +; ./helper-scripts/ipv6_tun/gen_4over6.pl -tun -count=200000 \ +; -in ip6_tun_bind_100k.lua -out lwAFTR_tun_100k.pcap +; ./helper-scripts/ipv6_tun/gen_4over6.pl -inet -count=200000 \ +; -in ip6_tun_bind_100k.lua -out lwAFTR_inet_100k.pcap +; The above sequence of invocations generates a binding table with 100k entries, +; written to file ip6_tun_bind_100k.lua (which the PROX configuration file needs +; to load in the [lua] section then assign using the "tun_bindings" parameter), +; and two pcap files to be used to generate traffic that will hit valid entries +; from the binding table. Each pcap file contains 200k packets of either IPv4 or +; IPv6 traffic. +;; + +[eal options] +-n=4 ; force number of memory channels +no-output=no ; disable DPDK debug output + +[port 0] +name=inet_0 +mac=00:00:00:00:00:01 +[port 1] +name=lwB4_0 +mac=00:00:00:00:00:03 + +[variables] +$tun_hop_limit=5 +$local_ipv6=fe80:0000:0000:0000:0100:00ff:fe00:0000 +$lookup_port_mask=0xffc0 + +[lua] +bindings = dofile("ip6_tun_bind.lua") + +[defaults] +mempool size=16K + +[global] +start time=20 +name=lwAFTR + +[core 0s0] +mode=master + +;***************************************************************************************** +;##### Send Internet IPv4 traffic into IPv6 tunnels, according to binding table #### +[core 1s0] +name=v6_encap +task=0 +mode=ipv6_encap +rx port=inet_0 +tx port=lwB4_0 +local ipv6=$local_ipv6 +tunnel hop limit=$tun_hop_limit +lookup port mask=$lookup_port_mask +tun_bindings=bindings +;***************************************************************************************** +;##### Terminate IPv6 tunnels and transmit IPv4 out to Internet #### +;# Binding table is checked to ensure src IPv4 address and port combo is allocated to the originating tunnel +[core 2s0] +name=v6_decap +task=0 +mode=ipv6_decap +rx port=lwB4_0 +tx port=inet_0 +dst mac=fe:80:00:ee:00:01 +local ipv6=$local_ipv6 +tunnel hop limit=$tun_hop_limit +lookup port mask=$lookup_port_mask +tun_bindings=bindings |
