I had one question about network command under bgp vrf subnode.

It does the same as if I was  using network under address-family subnode.
Right ?

If yes, then I suppose that the BGP daemon can be configured with 2
addresses families.
Let's suppose EVPN and VPNv4.
So, does that mean that the command is applied to both families ?

was possible to add vni subcommand under bgp vrf subnode.
As mentioned by cumulus documentation, the RDs are formed as "RouterID:VNI"
and the RTs (import and export) are formed using
"AS:VNI". Having that command under VRF coud mean that with VNI, the RD and
RT would be automatically set ?
