EVPN static IMET route on Bird 3.3.0

[André Grüneberg]

Hi again,

I have tried a few things and looked at a bit of code.

By now I learned from documentation that I cannot create a custom attribute
-- bgp_pmsi_tunnel already exists. And I cannot assign a bytestring -- the
documentation says it's not accessible in filters. Since the route
attribute is of T_OPAQUE, I also cannot assign a value in the static route.

The only place in the code accessing bgp_pmsi_tunnel is in
evpn_announce_imet(). So it seems I will need a minimal protocol evpn in my
config. Can I build one without having all the vxlan interfaces?
Note: I need the router address to be another system.

Thanks,
André
