3 ## Common configurations
7 create host-interface name eth1
8 set int ip addr host-eth1 A1::1/120

49 ## Drop-in for GTP-U over IPv4
51 What's happened when you run `test tmap`:
53 $ ./runner.py test tmap
56 Setting up a virtual interface of packet generator:
61 create packet-generator interface pg0
62 set int mac address pg0 aa:bb:cc:dd:ee:01
63 set int ip addr pg0 172.16.0.1/30
64 set ip arp pg0 172.16.0.2/30 aa:bb:cc:dd:ee:02
70 create packet-generator interface pg0
71 set int mac address pg0 aa:bb:cc:dd:ee:11
72 set int ip addr pg0 1.0.0.2/30
73 set ip arp pg0 1.0.0.1 aa:bb:cc:dd:ee:22
76 SRv6 and IP routing settings:
81 sr policy add bsid D1:: next D2:: next D3:: gtp4_removal sr_prefix D4::/32 v6src_prefix C1::/64
82 sr steer l3 172.20.0.1/32 via bsid D1::
89 sr localsid address D2:: behavior end
90 ip route add D3::/128 via host-eth2 A2::2
96 sr localsid address D3:: behavior end
97 ip route add D4::/32 via host-eth2 A3::2
103 sr localsid prefix D4::/32 behavior end.m.gtp4.e v4src_position 64
104 ip route add 172.20.0.1/32 via pg0 1.0.0.1
110 ## Packet generator and testing
112 Example how to build custom SRv6 packet in scapy and ipaddress pkgs
114 s = '\x11' * 4 + IPv4Address(u"192.168.192.10").packed + '\x11' * 8
116 IPv6(dst=ip6, src=ip6)
121 First set behavior so our localsid node is called with the packet
122 matching C1::1 in fib table
123 sr localsid address C1::1 behavior end.m.gtp4.ess
125 show sr localsids behaviors
128 We should send a well formated packet to C::1 destination address
129 that contains the correct spec as for end.m.gtp4.e with encapsulated
130 ipv4 src and dst address and teid with port for the conversion to
