I try to setup ip for server using /etc/conf.d/net.eth0
template="interface"
ipaddr="192.168.11.6/24 2a03:xxxx:xxxx:xxxx::6/64"
gateway="192.168.11.1"
gateway6="2a03:xxxx:xxxx:xxxx::"
but interface acquire 3 ipv6 addresses
# ifconfig eth0
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 192.168.11.6 netmask 255.255.255.0 broadcast 192.168.11.255
inet6 2a03:xxxx:xxxx:xxxx:aaaa:aaaa:aaaa:aaaa prefixlen 64 scopeid 0x0<global>
inet6 2a03:xxxx:xxxx:xxxx::6 prefixlen 64 scopeid 0x0<global>
inet6 fe80::aaaa:aaaa:aaaa:aaaa prefixlen 64 scopeid 0x20<link>

how can I exclude "2a03:xxxx:xxxx:xxxx:aaaa:aaaa:aaaa:aaaa"?
PS: neighbor discovery is enable on router and cannot be disabled because needed by other pc.
