# 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
