Hi,
The EBGP session failed between Juniper and other vendor with the following log
in Juniper Chassis.
Juniper chassis sent the Hold timer expired Notification and ceased the session.
Could you please let me know the reason for this Holdtime expiry? Were there
any TCP session failure or any Path MTU issues from the following log:
