The test is using a 3 node cluster with fwd, mobility, proxyarp, and openflow installed. The topology consists of 25 dual stack hosts. IPv6 forwarding is enabled in the fwd app.
We first perform an ipv4 pingall to discover the hosts, and it works fine. When we perform an IPv6 pingall, we can only ping some of the hosts and will eventually timeout.
We noticed that there is no MAC associated with the IPv6 address in Mininet for any given host.
We think that proxyarp cannot properly handle IPv6 arp requests.
