That depends. When the FIB gets too big, routers don't immediately die. Instead, their performance degrades. Just like what happens with oversubscription elsewhere in the system.If you consider blackholing traffic because the relevant next-hops aren't present in the FIB to be looked up as "degradation".... I guess?
Come on man, go re-read the post. The two paragraphs you cut literally explained what happens -instead of- routes dropping out of the FIB or being black holed. Regards, Bill Herrin -- William Herrin bill () herrin us https://bill.herrin.us/
