BGP multiple ASN

[jaimeco]

Hello everyone.

I have one prefix, e. g. 170.234.78.0/24 which is announced by e. g. ASN 28929 on IPv4, everything works fine with that.
Now, my organisation need to announce prefix IPv6, e. g. 2805:1a5::/48 with another ASN 273141

How can I configure multiple BGP instances with different ASNs? In GUI I cannot look nothing to do that.
I did try in CLI on /usr/local/etc/frr/bgpd.conf like the follow, with no success using VRF option in config file:

VRFs are only supported in Linux, not BSD. This wont work
