Hi,
As per RFC4486, the Cease code is a notification message to signal BGP reset:
If a BGP speaker decides to administratively reset the peering with a neighbor due to a configuration change other than the ones described above, then the speaker SHOULD send a NOTIFICATION message with the Error Code Cease and the Error Subcode "Other Configuration Change".
https://tools.ietf.org/html/rfc4486
This indicates that the local router has initiated a BGP session reset and has notified its peers about the reset.
Also, Notification messages are sent to signal an error.
The BGP session Uptime can be verified with "show bgp summary".
For the new neighbor, is it Established or down?
Can you check in the respective routing-table if you see an active direct route towards the peer as the BGP config suggests an eBGP. Is this a direct or multihop eBGP peering?
Hope this helps.
Cheers
Ashvin
