Explanation
Route databases are not in sync because:
- Churn rate is high ? many LSPs to flood
- Average rate 6.6 / second (as seen at test host)
- Peak rate 10 / second (as seen at test host)
- LSP rate control limits flooding
- 4 LSPs / second on each backbone link
- SPF updates may also be delayed by rate limits
Any topology change can result in a loop
- DC host link appears down due to LSP switching
