Issue

• How does IP source selection work in IPv6?
• An IPv6 source IP address is not expected, a VIP is used as a source instead of a real IP
• In RHEL 6.3 and earlier, it is not possible to influence the source address selection with the src directive as is possible in IPv4:

# ip route add 10.111.111.0/24 via 10.0.0.1 src 10.0.0.2
# ip route get 10.111.111.0
10.111.111.0 via 10.0.0.1 dev eth0 src 10.0.0.2    # desired source address is chosen

# ip -6 route add fc01:1111::0/64 via fc01::1 src fc01::2
# ip route get fc01:1111::0
fc01:1111:: via fc01::1 dev eth0 src fc01::3    # desired source address is NOT chosen
