Implement MP-BGP

[pl0xym0r]

MP-BGP was initially planned but not implemented

models session: afi_safi = None # for future use

• choices: class AFISAFIChoices(ChoiceSet):

Describe the solution you'd like
Implement MG BGP on the plugin

What is done on nautobot https://github.com/nautobot/nautobot-app-bgp-models/blob/develop/nautobot_bgp_models/models.py
but not sure it could cover all needs on MP-BGP

@k01ek what was in your mind for this feature at first?

Hi @pl0xym0r,

I too would like an AFI-SAFI/address families field on session. Can I suggest that the field is also included on peer group.

I agree there needs to be AFI-SAFI support for tracking things like redistribution, network statements, aggregate routes, multipath, add path, etc. Also need support for VRFs.

@ajackson79 For VRF support, please consider #127

@ajackson79 For VRF support, please consider #127

You need the vrf for a neighbor, but you also need it for the AFI/SAFI so you can track things like redistribution, network statements, aggregate routes, etc. Just adding vrf support to a neighbor is not enough to document everything.

I think AFI/SAFI should be just a choice field and it should include in unique_together, it will allow to create session with same src/dst/as/ip but with different afi/safi. As for VRF, my thought is same, we don't need to create new field to link VRF, becasue local IP address has this link.
