I need to confirm the below as i don't have access to a lab.
I have 4 XR boxes connected linearly as shown.Router A is advertsing PC subnet in isis. My understanding: So when the subnet of PC A reaches the Router D, the overall metric should be as
Cost of PC A to Router A link + 16777214(A-B link cost) + 16777214(B-C link cost) +16777214 (C-D link cost) But the max metric in isis is 16777214, so will the final route get installed or not? If so, with what metric?
With what metric will Router D learn the subnet of PC connected to Router A?
