Hello all,

Looking for any fresh experience with this:

https://docs.aws.amazon.com/vpn/latest/s2svpn/VPNTunnels.html

Any problems experienced with using that reserved space as a non-local destination? Seems like it might not be wise WRT RFC3927.

Apparently space from RFC1918 is not an option.

Found a few hits in the archives (2012) but looking recent experience.

Thank you very much in advance.

Using 169.254.0.0/16 or fe80::/64 Link-Local space as next-hop shouldn't
cause you to much of a head-egg. One point to remember is "just"
rewriting the next-hop address to a network reachable for your other
routers and switches to forward the traffic towards. (e.g. the loopback
address of your router peering with AWS Private Cloud)
