-# What's `runner.py` doing?
-
-## Common configurations
-
-### VPP1
-```
-create host-interface name eth1
-set int ip addr host-eth1 A1::1/120
-set int state host-eth1 up
-ip route add ::/0 via host-eth1 A1::2
-```
-
-
-### VPP2
-
-```
-create host-interface name eth1
-set int ip addr host-eth1 A1::2/120
-create host-interface name eth2
-set int ip addr host-eth2 A2::1/120
-set int state host-eth1 up
-set int state host-eth2 up
-ip route add ::/0 via host-eth2 A2::2
-```
-
-
-### VPP3
-
-```
-create host-interface name eth1
-set int ip addr host-eth1 A2::2/120
-create host-interface name eth2
-set int ip addr host-eth2 A3::1/120
-set int state host-eth1 up
-set int state host-eth2 up
-ip route add ::/0 via host-eth1 A2::1
-```
-
-### VPP4
-
-```
-create host-interface name eth1
-set int ip addr host-eth1 A3::2/120
-set int state host-eth1 up
-ip route add ::/0 via host-eth1 A3::1
-```

-## Drop-in for GTP-U over IPv4
-
-What's happened when you run `test tmap`:
-
- $ ./runner.py test tmap
-
-
-Setting up a virtual interface of packet generator:
-
-#### VPP1
-
-```
-create packet-generator interface pg0
-set int mac address pg0 aa:bb:cc:dd:ee:01
-set int ip addr pg0 172.16.0.1/30
-set ip arp pg0 172.16.0.2/30 aa:bb:cc:dd:ee:02
-```
-
-#### VPP4
-
-```
-create packet-generator interface pg0
-set int mac address pg0 aa:bb:cc:dd:ee:11
-set int ip addr pg0 1.0.0.2/30
-set ip arp pg0 1.0.0.1 aa:bb:cc:dd:ee:22
-```
-
-SRv6 and IP routing settings:
-
-#### VPP1
-
-```
-sr policy add bsid D1:: next D2:: next D3:: gtp4_removal sr_prefix D4::/32 v6src_prefix C1::/64
-sr steer l3 172.20.0.1/32 via bsid D1::
-
-```
-
-#### VPP2
-
-```
-sr localsid address D2:: behavior end
-ip route add D3::/128 via host-eth2 A2::2
-```
-
-#### VPP3
-
-```
-sr localsid address D3:: behavior end
-ip route add D4::/32 via host-eth2 A3::2
-```
-
-#### VPP4
-
-```
-sr localsid prefix D4::/32 behavior end.m.gtp4.e v4src_position 64
-ip route add 172.20.0.1/32 via pg0 1.0.0.1
-```

-## Packet generator and testing
-
- Example how to build custom SRv6 packet in scapy and ipaddress pkgs
-
- s = '\x11' * 4 + IPv4Address(u"192.168.192.10").packed + '\x11' * 8
- ip6 = IPv6Address(s)
- IPv6(dst=ip6, src=ip6)
-
-
-## end.m.gtp4.e
-
- First set behavior so our localsid node is called with the packet
- matching C1::1 in fib table
- sr localsid address C1::1 behavior end.m.gtp4.ess
-
- show sr localsids behaviors
- show sr localsid
-
- We should send a well formated packet to C::1 destination address
- that contains the correct spec as for end.m.gtp4.e with encapsulated
- ipv4 src and dst address and teid with port for the conversion to
- GTPU IPv4 packet
