Category: segment routing
I wanted to write a “SRv6 makes
no little sense” blog post for a long while, but there were always more relevant topics to focus on. Fortunately I won’t have to write it anytime soon; Ethan Banks did a fantastic job with SR(x)6 - Snake Oil Or Salvation?. Make sure you read it before attending the next “SRx6 will save the world” vendor presentation.
A while ago I made a statement along the lines of “MPLS segment routing is the best thing that happened to MPLS control plane in a decade”. Obviously some MPLS-focused engineers disagree with that and a few years ago I decided to write a lengthy blog post explaining the differences between using MPLS SR with IGP (or BGP) versus more traditional IGP+LDP approach.
Obviously, I wasn’t making any progress on that front, so the only way forward was to record a short video on the topic which didn’t work well either because the end-result was a set of three videos (available with free or paid ipSpace.net subscription).
One of my readers listened to a podcast where a $vendor described how they found another use case for
source routing IPv6 segment routing (SR): 5G networks… and wondered whether SR made a comeback or is about to.
To figure out what segment routing is, watch the webinar we did with Jeff Tantsura a while ago.
I don’t know nearly enough about mobile networks to have an opinion, however…
