# IPv4 and IPv6 functional tests focusing on VRF and routing lookups
# for various permutations:
#   1. icmp, tcp, udp and netfilter
#   2. client, server, no-server
#   3. global address on interface
#   4. global address on 'lo'
#   5. remote and local traffic
#   6. VRF and non-VRF permutations
#
# Setup:
#                     ns-A     |     ns-B
# No VRF case:
#    [ lo ]         [ eth1 ]---|---[ eth1 ]      [ lo ]
#                                                remote address
# VRF case:
#         [ red ]---[ eth1 ]---|---[ eth1 ]      [ lo ]
#
# ns-A:
#     eth1: 172.16.1.1/24, 2001:db8:1::1/64
#       lo: 127.0.0.1/8, ::1/128
#           172.16.2.1/32, 2001:db8:2::1/128
#      red: 127.0.0.1/8, ::1/128
#           172.16.3.1/32, 2001:db8:3::1/128
#
# ns-B:
#     eth1: 172.16.1.2/24, 2001:db8:1::2/64
#      lo2: 127.0.0.1/8, ::1/128
#           172.16.2.2/32, 2001:db8:2::2/128
#
# ns-A to ns-C connection - only for VRF and same config
# as ns-A to ns-B
#
# server / client nomenclature relative to ns-A
