Hi
It’s possible to implement a vrrp to work with /30 wan subnet?
My router is connected to provider by /30 bridge with vlan. I don’t know why but there was impossible to start succesfull connection without vlan.
On LAN side i have two /24 subnets public and local, so there is no problem to use 2 or more IPs, but wan is only single IP.
Hi There!
If you are placing 2 separate routers on the same broadcast domain (vlan), I tend to use VRRP with Private, unroutable IP’s and scripting. The private IP’s never have to be reachable, but within their own VLAN are perfect for determining which router is master which is not. You could then have on each router ‘On Master’ and ‘On Backup’ scripts, so when a router goes to ‘On Master’ it adds/enables your single WAN IP on it’s WAN interface, and ‘On Backup’ it can disable the IP on your WAN interface (assuming the other router goes into Master and runs it’s ‘On Master’ script to enable the WAN IP on it).
Hope that makes sense.
Thanks,
Joe
