Segment Routing to Replace 6PE | IOS-XE Configuration
I'm trying to confirm SR to replace 6PE in a lab that I'm running. I've attached a couple of pictures to show how I understand the setup to work (and to show how bad my handwritting is and how much I love to color code )
Firstly this is how I understand 6PE to work (assuming 2001:CAFE:BABE::/64 is a subnet which PE2 is receiving from some CE that isn't shown):
Stock standard 6PE. So to migrate to SR, I deploy v6 across the core, enable v6 loopbacks with appropriate Node-SIDs, and establish native IPv6 Unicast BGP sessions to the reflectors. SR is enabled and preferred. The setup should work as follows:
Im trying to set my lab up as you see above. But PE2 is IOS-XE and I cannot, for the life of me, find out how to give an IPv6 Loopback address a Node SID. IOS-XR is easy:
When I run the command 'sh controllers fabric fia q-depth location 0/0/CPU0' or any 0/X/CPU0 and see the following, what exactly does it mean? RP/0/RSP0/CPU0:Router#sh controllers fabric fia q-depth location 0/0/CPU0********** FIA-0 **********Categor...
