The former works, the latter breaks.
Funny, /127 works great for "real" point to point links (SDH). I tried it just now on an Ethernet link between a JunOS 11.4 box and an IOS XR 4.2.3 box in my lab - and it seems to work just great there too. What is the real usage of IPv6 subnet anycast? Steinar Haug, AS 2116
