Segment Routing Prefix SID's

[ThomasCampbell64]

Doing a multi-domain SR Lab and wondering if I need to configure different prefix-SID for each IGP

Running OSPF and IS-IS using absolute values. Can I use the same prefix-SID in the IS-IS/OSPF boarder router or do they they to be different?

No, you don't.

Yes, you need to use the same prefix-sid in both domains.
