Refer to the exhibit. An engineer configured IP SLA to monitor a next hop on a router for reachability. When the next hop is unreachable, the router is executing tracking and falling over another route, but packet loss is experienced because the reachability is flapping. Which action resolves the issue?
The issue described is packet loss due to flapping, which occurs when the tracked object frequently changes state between up and down. By appending 'delay up 60 down 60' to the track command, the system introduces a delay of 60 seconds before the state of the track object is considered down after initially determining it as down, and similarly, a delay of 60 seconds before considering it up after initially determining it as up. This helps to stabilize the tracking and prevents unnecessary state changes, thus reducing flapping and associated packet loss.
Agree on B
B correct. https://www.cisco.com/c/en/us/support/docs/smb/switches/cisco-550x-series-stackable-managed-switches/smb5797-configure-ip-sla-tracking-for-ipv4-static-routes-on-an-sg550.html
