When the available memory of a switch is low, the SOCK first send packets in high-priority queues to the CPU. When the available memory is very low, the SOCK sends only Hello packets to the CPU. As a result, LSAs in the OSPF LSDB cannot be updated. When the age of LSAs reaches 3600s, OSPF cannot calculate routes. Because ACK packets are not sent to the CPU, LSAs in the LSDB cannot be aged. To address this problem, you can adjust the memory usage threshold, delete unwanted sub-interfaces, and expand memory capacity. S9700, S7700 |
