BGP Peer Hold Timer Error

Fri Apr 08, 2022 11:23 am

I am receiving the following BGP notifications and errors and the remote user said the problem is on my side:

Connection terminated
Received notification
Hold timer expired, subcode=0

Peer config:
name="Provider1" instance=default remote-address= remote-as=####### tcp-md5-key="" nexthop-choice=default multihop=no route-reflect=no hold-time=3m ttl=default in-filter=Microsoft-in out-filter=Microsoft-out address-families=ip default-originate=never remove-private-as=no as-override=no passive=no use-bfd=no

We aren't seeing packet loss via the cross connect. The BGP connection last some nights for 16 hours and once it start timing out, it continues and doesn't last more then 5min

We’ve had a similar problem on our backbone. It seems that was generated by a flapping link.
It seems that in the middle of the exchange some data get lost, generating that error. The ugliest thing is the error is spread to all other peers.
