Hi,
I have two RB450G with 5.12 version.
On both i have interface named "LAN" with normal local ip (10.23.2.3/24) and (10.23.2.4/24). Ofcorse this automatically implicates to have routes (DAC - 10.23.2.0/24 gateway: LAN).
After setting up VRRP with shared IP 10.23.2.1, network: 10.23.2.1 on new vrrp-lan interface, everthing works.
Problem (or bug) is, that after mikrotik reboot. it looses its own ip route for local network (DAC as mentioned before). Router does not respond to direct ping or anything else. After going to IP address list, changing interface for my ip 10.23.2.3/24 from LAN to wan (or anything else), and making option back to LAN. DAC ip route is created and everything works.
Maybe the problem is when powering on and loading configuration with wrong config order, becase DAC should always be presented.
One approach could be to write startup script to recreate normal local ip, which will recreate DAC ip route.
Please advise.

Post your VRRP configuration from both routers.

Re: Route problem for LAN with VRRP , is a bug ?
Hi,
After few reboots of both routers it seems it runs fine. However maybe sometimes, after boot, my LACP and VLAN interfaces are not ready so it want assigne this ip addres and create DAC route for interfaces. (it has IP address, but can not ping anybody on local network except itself, DAC route is missing, recreating IP address with /24 fixes the issue). Maybe this does not have nothing with VRRP at all.
First router (master):
Second router (slave):

Re: Route problem for LAN with VRRP , is a bug ?
I posted in another post also on VRRP - i think perhaps something comes up out of order and you may need to change priority (or disable/enable) the vrrp interface and see if things come back up properly (instead of rebooting). That may give them another hint.
Is there any way to log more info about the ip addresses / interfaces / routes being added/removed when it occurs due to interface coming up/down?

Re: Route problem for LAN with VRRP , is a bug ?
After few reboots, did not help, but after few days, it worked normally. Yes, problem is with interface up/down order. Now it is running for a weeks.
I could not figure how to change interface up/down order on boot.
