By default ipv6 nbrs are activated in IPv4 address family , you will have to disable them explicitly

“no neighbor xx::xx activate”

Thanks,

Hi all,

I'm using frr-7.2.1-s3, I found command of `show ip bgp sum` shows ipv6 neighbors in ipv4 address-family, like this.

Is this a bug?

```

dut-testbed(config-router)# do show ip bgp ipv6 summary
