Could you please elaborate more on what means “LFA coverage on an interface”?
Say, we execute “show ip ospf fast-reroute prefix-summary” and we get this statistics per interface.
It’s quite confusing though. What means “100% of prefixes are protected on an interface”? Whose prefixes? All prefixes that are being kept in ospf database of a given router? In some labs I’ve seen tweaking cost value on some links to make this LSA coverage = 100% for an interface. In Cisco docs there’s some “madness” with several inequalities. This is one of the most complicated topics in the whole CCIE blueprint probably.
