VPP is a data plane.
There are various ways of integrating with routing protocols. The simplest is
likely to use the linux-cp plugin and use linux as the control plane.

The “via” should be the address of the next-hop, not the locally assigned

If the default router has an address within that /29 you don’t need this route
at all, just the default route via the default router address.

Actually no. Geneve isn’t like a typical UDP application where receiver
reverses the ports.
The IANA allocated port is used as the destination port in both directions.
Making the source port purely used for entropy.
Of course for v6 the whole UDP header would largely be superfluous.

The VPP binary API supports two transports. Shared memory and unix domain

VAPI is the C language binding for the binary API. I think it only supports

Nothing will ever be enough. Which is good, then we would be out of jobs. :-)
The general problem to API stability does not have a solution.
It's a continual tussle
API users,
This summer we found an error in the crc generation and to avoid forcing API
users to update their manifests on short notice I put in 9f84e70c6d.
Which "cheats" and returns the old crc value instead of the correct crc value
for a set of messages.

The tunnel encapsulation limit option has never been specified for GRE. It's
arguable if this is a protocol compliant packet.
It is also largely
