Serious? A huge amount of traffic sent over the Internet is multipath due to ECMP. Hashing on the full src/dst ip and port tuple makes for stable path selection

Serious? A huge amount of traffic sent over the Internet is multipath due to ECMP. Hashing on the full src/dst ip and port tuple makes for stable path selection. WRT to the second point, failure cases are not that simple. Edit: lets talk directly connected next hops, like a L2 domain. In this scenario what's the difference between "Anycast" and "ECMP"?
