You have configured a GRE tunnel. To reduce the risk of dropping traffic, you have configured a keepalive OAM probe to monitor the state of the tunnel; however, traffic drops are still occurring.
Referring to the exhibit, what is the problem?

The problem is that the hold time value must be two times the keepalive-time value. In the given configuration, both the keepalive-time and the hold-time are set to 10, which does not meet the requirement. The hold time must be at least twice the keepalive time to ensure that the GRE tunnel properly detects failures and minimizes traffic drops.
Note that the hold time must be at least twice the keepalive time.https://www.juniper.net/documentation/us/en/software/junos/interfaces-security-devices/topics/topic-map/security-interface-config-gre-keepalive-time.html#:~:text=Configure%20the%20keepalive%20time%20from,for%20the%20GRE%20tunnel%20interface.&text=Configure%20the%20hold%20time%20from,least%20twice%20the%20keepalive%20time.
