I’ve been chasing down an IPv6 bug that’s been a little difficult to work out.

The circumstances are as follows:

Internet connection is PPPoE

DHCPv6 Client attached to PPP interface
/ipv6 dhcp-client
add add-default-route=yes interface=Internode pool-name=NODE-PD

IPv6 address from DHCPv6 Pool
/ipv6 address
add address=::1 from-pool=NODE-PD interface=LAN

(LAN interface is bridge of wireless and local switchports)

This works fine:
ping ipv6.google.com:

If you do any of the following:
disable/enable dhcpv6-client
disable/enable pppoe-client interface
release/renew dhcpv6 pool
or
ppp drops out

then it appears that this mechanism breaks:

IPv6 address from DHCPv6 Pool
/ipv6 address
add address=::1 from-pool=NODE-PD interface=LAN

and ipv6 pings will time out:
Request timed out.
Request timed out.
Request timed out.
Request timed out.
Request timed out.

disabling/reenabling the ipv6 address resolves the issue:
