Hello, I have a problem configuring VRRP in IPv6, two layer 3 switches are doing VRRP redundancy towards 4 LAN networks, as follows:
It shows me the following error in the log, some networks the VRRP works, in others it doesn’t, in some the master router works well, in the other networks it doesn’t, can someone please advise me?
NFCT_SLAVE: could not open NETLINK socket (93) - Protocol not supported
error in the log
Someone else recently had troubles with IPv6 and VRRP, see http://forum.mikrotik.com/t/ipv6-vrrp-oddness/177606/1 So possible it’s a bug.
Was this working before, or is this first time setting up VRRP with IPv6?
it is worth mentioning that it is an emulation in gns3, it works for a single LAN, but when I create several vrrp instances for several LANs in a pair of Switches with Router OS 7.1.5 and 7.8, it also only works well for one LAN, for the others it does not work, when I configure DHCPv6, should it be the same configuration for both switches? it is strange because in IPv4 it works for the 4 LANs that I have in gns3. Knowing that I have the same configuration for each LAN in both ipv4 and ipv6, it seems to be a limitation of the emulation.
But VRRP has changed (i.e. added sync-connections, grouping, etc) between 7.1.5 and 7.8. So I’m not sure mixing versions is a good idea.
I’m not the expert on IPv6 with VRRP. With IPv4, I have DHCP server listen on the VRRP interface (so it becoming disabled on a non-active VRRP member). But cannot say whether that’s good/bad with IPv6.
And how do you do that? Now vrrp doesn’t want to work even for a LAN? I’m currently working with ospf, should ospf send hello messages to the vrrp interface in ipv6? Could you help me with an example of a vrrp configuration in ipv6? Very kind and thanks for answering.
