Messing around with NCSI code and adding logging, it appreas the EGMF is never set up until an IP address is added. After that happens pinging ff02::1 works. ``` [...

While RA works ff02::1 does not seem to work, so still something odd with multicast

There are some NC-SI stuff in the second to last firmware release, and the cards on these particular host had a pretty old firmware. Tried upgrading the CX3 MCX342A card...

Doing a full power cycle seems to have brought back the state where pinging over Ipv6 does not work - on both sites. So there needs to be more debugging...

Debugging this some more, it looks like solicited multicast does not work: ``` $ sudo tcpdump -i ens224 'ether host 33:33:ff:41:03:f0' listening on ens224, link-type EN10MB (Ethernet), capture size 262144...

Yep, that works. ``` /# ./dumpcap -filter 'ether host 33:33:ff:41:03:f0' PACKET: 90 bytes, wire length 90 cap length 90 @ 1970-01-01 00:03:09.407245 +0000 UTC - Layer 1 (14 bytes) =...

From the standard: ``` IPv6 Neighbor Solicitation messages are not covered by the currently defined multicast filters. When multicast, Neighbor Solicitation messages are sent to a Solicited Node multicast address...

Re-opening to track the long term resolution of this.

It's an artifact from the way I used to do flags. Those are legacy anyway, so we should just remove them.

Yet another alternative: IS25LP512M-RMLE The locking functionality is not the same in these chips, which does not come as a surprise. That means that to support this we need a...
