I have one Router(first one in image), acted as CapMan, and 7 APs. All upgrade from 7.22.3 to 7.23.1

  1. download .npk files and upload to router
  2. restart router to let it upgrade to 7.23.1
  3. after router booted, and all CAP (still stay at 7.22.3) connected, CapMan will let CAP download 7.23.1 npk files and auto upgrade
  4. then all CAP rebooted and upgrade themself to 7.23.1
  5. after a while, IPv6 traffic were down: machines cannot ping outside via router and outside cannot ping inside via router.

Then I found in /ipv6/neighbor:

Flags: D - DYNAMIC; R - ROUTER
Columns: ADDRESS, MAC-ADDRESS, INTERFACE, VRF
 #    ADDRESS                               MAC-ADDRESS        INTERFACE  VRF
 0 DR fe80::1                               3C:A1:61:6C:E9:44  ether1     main
 1 DR fe80::2ec8:1bff:fe4a:828f             2C:C8:1B:4A:82:8F  bridge     main
 4 DR fe80::2ec8:1bff:fe4a:805b             2C:C8:1B:4A:80:5B  bridge     main

It means two CAPs from bridge sent IPv6 RA and router and other machines accepted. Router ipv6 route table was

Flags: D - DYNAMIC; X - DISABLED, I - INACTIVE, A - ACTIVE; c - CONNECT, s - STATIC, r - RIP, b - BGP, o - OSPF, i - IS-IS, d - DHCP, v - VPN, m - MODEM, g - SLAAC, y - BGP-MPLS-VPN;
H - HW-OFFLOADED; + - ECMP
   DAg + dst-address=::/0 routing-table=main gateway=fe80::2ec8:1bff:fe4a:828f%bridge immediate-gw=fe80::2ec8:1bff:fe4a:828f%bridge distance=0 scope=30 target-scope=10

   D v   dst-address=::/0 routing-table=main gateway=pppoe immediate-gw=pppoe distance=1 scope=30 target-scope=10 vrf-interface=pppoe

   DAg + dst-address=::/0 routing-table=main gateway=fe80::da86:8eff:fea1:37%pppoe immediate-gw=fe80::da86:8eff:fea1:37%pppoe distance=0 scope=30 target-scope=10

   DAg + dst-address=::/0 routing-table=main gateway=fe80::2ec8:1bff:fe4a:805b%bridge immediate-gw=fe80::2ec8:1bff:fe4a:805b%bridge distance=0 scope=30 target-scope=10

So ipv6 traffic send to wrong gateways.

I don't know why CAPs send ipv6 RA. So I logined to every CAP and disable items under /ipv6/nd

Then everything works well.

I found 3 CAPs ipv6 enabled in (/ipv6/settings/print) while other CAPs are all disabled. So I also turn off ipv6 of all CAPs.

Anyone has better solution?
