Dear all,
I think currently Cisco's major SR supported product is IOS-XR right?
Because there is a lot of configuration examples easy to understand and some dCloud scenario which normally IOS-XR configuration and operation.
However in my understanding, other products such as ASR1K IOS-XE and Nexus3K/9K NX-OS also support but it is pretty difficult to confirm the feature difference. I appreciate if there is any pros and cons on the following products.
1.Cisco ASR9K/NCS - IOS-XR

2.Cisco ASR1K - IOS-XE

3.Cisco Nexus3K/9K - NX-OS

As for the Segment Routing, I think if I can understand the following technical keyword, then it is much easier to explain for the customers who are interested in SR or equivalent demand.
Technical Keyword:
SR-MPLS(RSVP/LDP)
SR-MPLS(IGP)
SRv6
BGP-LU for interdomain between DC/Metro/WAN
RSVP-TE to SR-TE
On-Demand Next Hop
Enhanced FRR (TI-LFA)
SR-PCE(SDN) for total solution (Network Programming)
RFC Standard Connection with third party product
