PPP CCP ECHO problem of Mikrotik v2.9.27

RouterOS General
1

Hi!
I use Mikrotik to work as BRAS, the ppp profile is:

 1   name="ppp_prof" local-address=120.0.0.1 remote-address=ppp_pool use-compression=default 
     use-vj-compression=default use-encryption=default only-one=yes change-tcp-mss=default

I found for each pppoe session, Mikrotik will send out PPP CCP echo request every 1 sec, I do not think these CCP echo request packets are useful for the pppoe session, ang why Mikrotik will send out CCP ECHO request packets so frequently? Because I can not find a parameter to configure it.

Blue letters show 5 consecutive PPP CCP ECHO requests with tyhe period 1s.

Could I disable LCP CCP in Mikrotik? I am using v2.9.27

Best Regards
