Re: IBGP flap when MX80 received 1.3m full internet route?
3 weeks ago
From what it looks, your MX80 is under both CPU (100% last 1 minute) and memory pressure(80%) . Thus it is likely to flap other protocols.
Need further check a few things:
1. What version is running on MX80?
2. rpd is likely to consume high memory if you receive 2 copies of internet routes. But let's check "show system processes extensive" and see apart from rpd, what else is consuming high memory(maybe you also have sampling enabled) ?
3. For your IBGP (or probably other protocols), is it one time flap or continuous flap? If this is one time flap, that means system is not able to keep up with the changes of route update. This can be avoided by tuning protocol timers, disable traceoption. If this is continuous flap, it would point to scaling limit or some other issues
A few log stamps you can search in your "show log messages" file (but not limited to those)
