When a VXLAN tunnel is given a self IP, addresses on that IP's network can be pinged through the VXLAN tunnel. Two BIG-IP systems can ping each other in that manner through a VXLAN tunnel to which both belong. However, if the self IP is an IPv6 address, two BIG-IP systems cannot ping each other.
Pinging a VXLAN tunnel self IPv6 address results in network unreachable messages.
This occurs when VXLAN tunnels configured with self IPv6 addresses.
A workaround is to associate a VXLAN tunnel with a VLAN group.
VXLAN tunnel self IPv6 addresses can be pinged.
