SRv6 support

[Sébastien PARISOT]

Hello,

I wonder if there is any feedback on the content of patch? Just so I know if it is in the right direction or if anyone sees any issues the way it is implemented.

BTW, about the next patches (BGP and netlink), I (re)discovered some parts that are not so good and that I need to improve.

Thanks,
Sébastien

Hello Ondrej,

Great, thanks for the feedback. Interesting, is there a branch in BIRD gitlab with this work on OSPFv3? I agree, there should be a single SRv6 implementation in the nest and a single SID allocator (that I did not implement).

It is not a 100% complete support (at least the SID allocator is missing: we use static routes to bind the routes to a specific SID), but it is enough to act as a PE, there is BGP support and it installs remote SRv6 routes in the Linux kernel SRv6 using netlink.

Hello

We are interested. In fact, there is already some work on SRv6
(specifically SRv6 for OSPFv3) done by an external contributor,
so we should do some merge work here.
