In this scenario, the LLDP PDU with destination MAC 01:80:c2:00:00:00, which is one of the three reserved MAC addresses for LLDP in IEEE 802.1AB, will be ignored by Juniper LLDP process, and this causes the LLDP function failure.

PR Number	Synopsis	Category: Border Gateway Protocol
1487691	High CPU utilization might be observed when the outgoing BGP updates are sending slowly Product-Group=junos	On all Junos platforms with the BGP routing protocols, the rpd process might go into a high CPU utilization causing slow network convergence. If a BGP peer is receiving and processing BGP updates slowly, this may cause the BGP output queue of the sending BGP peer to be full. When the queue is full it causes high CPU utilization of the BGP IO thread (bgpio, it is part of the rpd daemon) on the sending BGP peer. This defect could cause network-wide slow BGP network convergence. (See also https://kb.juniper.net/TSB17725)
