  • So this isn’t about routing really, rather about optimizing standby routers for recovery.

    A few things make me nervous.

    First, the description of the work involved seems to imply that your setup really needs more automated tooling. Nontrivial, but you’ve already mentioned typos, and that this is for large operations.

    Second, using IPv4 for your management network is wasteful and needlessly complicated. Even if your customer traffic is all IPv4, there’s really no reason to use legacy protocols for internal routing.




  • I’m not sure that I understand the benefit of “unnumbered” routing. It sounds like there are numbers (well, “identifiers”), just not IP addresses.

    It’s hard to know without more context, but you can use things like IPv6 multicast to manage reachability. This will let you set arbitrary sets of endpoints that talk to each other, and you can still us IP-based tools to debug connectivity, measure performance, and so on.
