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 occurs on the GR restarter, the GR helper marks all
routes learned from the GR restarter as stale and 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
# Configure the GR timer as 300 seconds.
<Sysname> system-view
[Sysname] bgp 100
[Sysname-bgp] graceful-restart
[Sysname-bgp] graceful-restart timer restart 300
