-# GENEVE
-
-## GENEVE Prefix Bindings
-
-GENEVE prefix bindings should be representative to target applications, where
-a packet flows of particular set of IPv4 addresses (L3 underlay network) is
-routed via dedicated GENEVE interface by building an L2 overlay.
-
-Private address ranges to be used in tests:
-
-- East hosts ip address range: 10.0.1.0 - 10.127.255.255 (10.0/9 prefix)
-
- - Total of 2^23 - 256 (8 388 352) of usable IPv4 addresses
- - Usable in tests for up to 32 767 GENEVE tunnels (IPv4 underlay networks)
-
-- West hosts ip address range: 10.128.1.0 - 10.255.255.255 (10.128/9 prefix)
-
- - Total of 2^23 - 256 (8 388 352) of usable IPv4 addresses
- - Usable in tests for up to 32 767 GENEVE tunnels (IPv4 underlay networks)
-
-## GENEVE Tunnel Scale
-
-If N is a number of GENEVE tunnels (and IPv4 underlay networks) then TG sends
-256 packet flows in every of N different sets:
-
-- i = 1,2,3, ... N - GENEVE tunnel index
-
-- East-West direction: GENEVE encapsulated packets
-
- - Outer IP header:
-
- - src ip: 1.1.1.1
-
- - dst ip: 1.1.1.2
-
- - GENEVE header:
-
- - vni: i
-
- - Inner IP header:
-
- - src_ip_range(i) = 10.(0 + rounddown(i/255)).(modulo(i/255)).(0-to-255)
-
- - dst_ip_range(i) = 10.(128 + rounddown(i/255)).(modulo(i/255)).(0-to-255)
-
-- West-East direction: non-encapsulated packets
-
- - IP header:
-
- - src_ip_range(i) = 10.(128 + rounddown(i/255)).(modulo(i/255)).(0-to-255)
-
- - dst_ip_range(i) = 10.(0 + rounddown(i/255)).(modulo(i/255)).(0-to-255)
