Hello,
I’m new to MikroTik ROS, though I have basic knowledge regarding Linux firewalls and general ip networking.
I’m using a RB760iGS (hEXs) on v7.2rc3 in my home network.
I got two internet connections (fibre and DSL).
The fibre ONT is connected to ether1. VLAN 360 on ether1 is the WAN interface (named “dg_360_internet”).
The router board is running DHCPv4 and DHCPv6 clients on the WAN interface (VLAN 360)
I get assigned IPv6 address and prefix. (pool name: DG1)
The LAN interface is named bridgeLocal.
Present on this interface is the CPE for my DSL connection. The CPE is a F****B** 7590 configured as router.
The CPE works as IPv4 multicast router.
DHCPv4, IPv6 router advertisements and DHCPv6 address assignment (IA_NA) are disabled on the DSL CPE.
DHCPv6 prefix delegation (IA_PD) is enabled on the CPE.
The router board is requesting a prefix from the DSL CPE. (pool name: rb1)

Columns: INTERFACE, STATUS, REQUEST, PREFIX

9 DG 2000:ffff:1000:33::1234/64 dg_360_internet no
10 G 2000:ffff:ffff:ff00::/64 DG1 bridgeLocal yes
The link local addresses were omitted.
Please note the only for address # 10 the advertise flag is yes.
I noted that i got two (DHCP created) default routes for the same interface:
> /ipv6/route/print
Flags: D - DYNAMIC; A - ACTIVE; c, d, y - COPY; + - ECMP
Columns: DST-ADDRESS, GATEWAY, DISTANCE
DST-ADDRESS GATEWAY DISTANCE
DAd+ ::/0 fe80::ff:fe02:202%dg_360_internet 2
DAd+ ::/0 fe80::ff:fe02:202%dg_360_internet 2
D d ::/0 fe80::464e:6dff:fe00:0000%bridgeLocal 5
This address # 10 disappears when i restart the router board.
Therefore I need to re-add the address manually to re-enable IPv6 functionality for the LAN after each reboot.
Does anybody know how to avoid this?
Thank you very much!
