Usage guidelines
The GR restarter sends the GR timer to the GR helper in an Open message. When the GR helper detects that an active/standby switchover or a BGP restart occurred on the GR restarter, the GR helper performs the following operations:
Marks all routes learned from the GR restarter as stale.
Starts the GR timer.
If no BGP session is established before the GR timer expires, the GR helper removes the stale routes.
Before you configure this command, enable the BGP GR capability.
To apply a new GR timer, you must re-establish BGP sessions.
Examples
# Set the GR timer to 300 seconds.
