VyOS slow to get wan pppoe ipv6 address after disconnect and reconnect pppoe interface

Description

Hi all:

Topology:

VyOS——ISP

I find VyOS always slow to get wan pppoe ipv6 address after disconnect and reconnect pppoe interface via cli or unplug/plug cable line. I can get same results by using VyOS as pppoe server, so, It seems that is not ISP's fault.

This is my configuration from VyOS client.

vyos@vyos:~$ show configuration commands

This is my configuration from VyOS server.

It can get wan's ipv4 address and lan's ipv4/ipv6 address and ipv6 prefix quick enough after reconnect pppoe server but not wan's ipv6 address even if I find vyos already get the RA packet.

This is the ndp log, it tooks about 10 minute to get ipv6 address.
