IPv6 Disable Router Advertisement / Static Routing

[CobbyJ]

Hello.

We have setup a IPv6 IP on a vLan which we use as a gateway for our pfsense but the issue is that the ipv6 on the vlan is advertising IP's which we want to disable.

I have tried a few different things but with no luck.

Can anyone give any advice on how to stop the vlan advertising IP's please?

Kind Regards,

Chris

Hi @CobbyJ ,

Are you referring to the ipv6 prefixe(s) being advertised by the router advertisement (RA)? If you want to prevent RA to contain prefixes that the other hosts on the subnet might try to autoconfig themselves from, I would suggest using the following command:

Int Gigx/x

ipv6 nd prefix default no-advertise
