My rc.conf config has:
ifconfig_genet0_ipv6="inet6 accept_rtadv"

Can you post the output of "ifconfig" and "ipfw show"?
Can you ping the link-local address of the other hosts?

Regards.
Ronald.

Onderwerp: what to check? no IPV6 pings between nodes on the same switch

 
I have setup 3 nodes on a fresh Freebsd 13.1-RELEASE-p1. They have the same gateway and IPS are in same /64. All 3 nodes are on the same switch (mikrotik) and same vlan untagged.

I can ping them from an external machine through the router/gateway but the nodes can't ping each others. When I run `ndp-a` it only return the gateway and the node ipv6 (+ their libks) but not the ips of the other nodes.

Previously these nodes wee under linux and were able to ping each others.

What could be the issue? What do I need to check?

Configuration is pretty straightforward:
 
```

hostname="node1.domain.tld"

keymap="fr.macbook.kbd"

ifconfig_ql0=""

ifconfig_ql0_ipv6="inet6 <PREFIX>::11/64"

ipv6_defaultrouter="<PREFIX>::1"

sshd_enable="YES"

ntpd_enable="YES"

# Set dumpdev to "AUTO" to enable crash dumps, "NO" to disable

dumpdev="AUTO"

zfs_enable="YES"

```
 
Others machines are `<PREFIX>::12`, `<PREFIX>::13`Sent from Proton Mail for iOS
