New Virtual Interface Type - Bridge

[adamboutcher]

Environment

• Python version: 3.6.8
• NetBox version: 2.9.8

Proposed Functionality

Can we add Bridge as an Interface type that allows parent/child on interfaces.

Use Case

Would help document virtual bridges much like LAGs.
Would need to accept LAGS to be a child of a BRIDGE.

Database Changes

External Dependencies

Are you creating a software bridge inside of a router? Is it a VLAN aware bridge? If so, would just assigning the vlan memberships be enough to show correlation between ports?

[adamboutcher]

It's simply a bridge inside a linux router (eg vmbr0).

Our usecase is that we bond multiple interfaces and then add that bond to a bridge.

eth[0-1] -> bond0 -> vmbr0

What would be the practical difference between a "virtual" interface and a "bridge" interface?

[adamboutcher]

Nothing if you could parent/child a virtual interface.

LAG can only be a parent.
Interfaces can only be children.

If you could make a LAG a child to a Virtual Interface then that would work.

A change to the whole parent/child of interfaces and lags to be less strict would allow for more accurate documentation.

I merely suggested bridge as my use case and kept with the current more strict existing code.

[jeremystretch]

Would #1519 address this?

[adamboutcher]

Similar but not exact.
The work done for that issue could be applied here though, as long as you can make a LAG a child to a Virtual Interface.

It would be really cool to have an interface type bridge similar to the LAG type so you can set other interface to be part of this bridge. With the already existing functionality of .1q settings on interfaces it would thereby even be possible to model vlan-aware-bridges.

This still would be a really really helpful for modelling network on virtualization hosts and routers <3

NetBox v2.11 introduces parent interface assignments (see #1519), which seems like it addresses most of the desired functionality discussed here. I'm going to close this issue out, however if there's still a particular feature you believe is not addressed under #1519, I encourage you to open a new feature request (with a detailed description and use case) considering the newly introduced support for parent interfaces.
