Gateway group with two Tier 1 IPv6 gateways only shows a single default route with netstat -rnW6

techstone

Hi,

I have a pfSense cluster with each box connected to two gateways. I am using the following gateway group with two Tier 1 IPv6 gateways.

I have defined the default IPv6 gateway to use this gateway group:

When I look at the output of netstat -rnW6 I only see one default gateway though:

I expected to see two default routes, but I suspect I may have wrong expectations. I also observed that the traffic is only sent to the gateway in the routing table (i.e. there is no traffic spread accross the two defined Tier 1 gateways). If the gateway in the routing table goes down, it does eventually fail over to the other gateway however.

What is the correct way for me to get traffic spread across the two gateways?
