Hello,
We have a Mikrotik CCR 1072 and some days ago we had some ddos attack then we announce the attacked prefixes towards our ddos protected IP transits but after time about 1-2 days later we cpu our cpu usages are about %40-45 and our memory normally is 15g but its 14g then we found out that the issue is with IP route cache , when i disable that my cpu usages back to under %6-8 and memory back to 15g so:
1) if i keep route cache disabled do i face any issue? i just disable connection tracking and i have some bgp and clans and routing protocols, so disabling route cache does not cause any issue?
2) do you have any idea how to fix this by enable IP route cache?
Thanks,
