求教ASR1006出现这些现象是存在环路吗?

最近整理设备端口表时,在cdp邻居里看到了设备自己:
ASR1006_02#show cdp nei
Device ID Local Intrfce Holdtme Capability Platform Port ID
ASR1006_02 Ser 0/0/0.1/2/4/1 135 R I ASR1006 Ser 0/0/0.1/2/4/1:0
ASR1006_02 Ser 0/1/0.1/2/3/2 154 R I ASR1006 Ser 0/1/0.1/2/3/2:0
端口配置如下,没有配置loopback口:
interface Serial0/0/0.1/2/4/1:0
description to SY
ip address 172.28.198.37 255.255.255.252
cdp enable
使用show interface查看端口状态,存在一个looped:
ASR1006_02#show interface
Serial0/0/0.1/2/4/1:0 is up, line protocol is up (looped)

请问这是怎么回事啊?是存在环路吗?但使用中一直没有出现问题啊,CPU占用也很低。

对端或者运营商在打环测试吧

CDP邻居看到自己也是对端打环测试引起的吗?会有什么影响吗?有隐患吗?

没隐患,如果没用了,联系运营商查一下那段在打环,把环拆掉。
