Interesting... I've never heard of SPRINGv4 https://www.juniper.net/us/en/products-services/routing/ptx-series/datasheet s/1000538.page
I found it in the bottom section I wonder if SPRINGv4 is like SRv6, meaning, SPRING(SR) over IPv4 dataplane? Or, am I reading way too much into that SPRINGv4 acronym? -Aaron
