Title: our AdvLinkMTU on vtnet0 doesn't agree with fe80::192:168:1:1
Post by: klingon888 on August 09, 2024, 03:05:57 PM
I'm getting these warnings in my logs in both Master and Backup servers. How to fix? Thanks.

radvd: our AdvLinkMTU on vtnet0 doesn't agree with fe80::192:168:1:1

- vtnet0 is my LAN
- fe80::192:168:1:1 is my VIP link local address setup according to https://docs.opnsense.org/manual/how-tos/carp.html#setup-virtual-ipv6-link-local-address (https://docs.opnsense.org/manual/how-tos/carp.html#setup-virtual-ipv6-link-local-address)
- IPv6 is setup as SLAAC
- MTU is left at defaults, not configured in any interfaces
