# 查看Device A上分布式聚合的Keepalive报文信息。

[DeviceA] display drni keepalive

Neighbor keepalive link status: Up

Neighbor is alive for: 104 sec, 16 ms

Last keepalive packet sending time: 2017/03/09 10:12:09 620 ms

Last keepalive packet receiving status: Successful

Last keepalive packet receiving time: 2017/03/09 10:12:09 707 ms

Distributed relay keepalive parameters:
