Dear Colleagues, Why could it be that a FreeBSD 12.2 host does not reply to ICMPv6 Neighbor Solicitations from the router?
Interface configuration on host: $ ifconfig re1 re1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=8209b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,WOL_MAGIC,LINKSTATE> ether c4:12:f5:33:c9:7c inet 192.168.170.5/24 broadcast 192.168.170.255 inet6 fe80::c612:f5ff:fe33:c97c%re1/64 scopeid 0x2 inet6 2001:470:ecba:3::5/64 media: Ethernet autoselect (1000baseT <full-duplex>) status: active nd6 options=21<PERFORMNUD,AUTO_LINKLOCAL> $ Interface configuration on router: [admin@MikroTik] > /ipv6 address print where interface=bridge Flags: X - disabled, I - invalid, D - dynamic, G - global, L - link-local # ADDRESS FROM-POOL INTERFACE 0 DL fe80::4a8f:5aff:feab:b0c1/64 bridge 1 G 2001:470:ecba:3::1/64 bridge [admin@MikroTik] > Packet dump: http://admin.sibptus.ru/~vas/nd1.pcapng where I ping a host in the IPv6 Internet from 2001:470:ecba:3::5, the router wants to learn the L2 address for 2001:470:ecba:3::5 to reply to, and receives no answer. Where could be the problem? -- Victor Sudakov, VAS4-RIPE, VAS47-RIPN 2:5005/49@fidonet http://vas.tomsk.ru/
