Each routing table is identified by the protocol family
or address family indicator (AFI) and a subsequent address family
identifier (SAFI). The AFI parameter can be one of the (l2vpn
| inet | route-target) protocols and the SAFI parameter can
be either of the (flow | labeled-unicast) protocols for
inet family and one of the (auto-discovery-mspw | auto-discovery-only
| signaling) protcols for L2VPN family..
Configuring LLGR does not require that BGP graceful restart also be configured. The long-lived-graceful-restart section is visible only for families l2vpn, inet labeled-unicast, inet flow and route-target. It is prohibited for inet-mvpn, inet6-mvpn and inet-mdt. It is hidden for other families.
Description
Configure the graceful restart capability for long-lived BGP sessions on the restarting router to enable BGP routing details to be retained for a longer period. It in important to retain BGP data for a longer period when the BGP control plane fails for some reason for slowly-restarting routers for a longer duration. You can define the time period for which the stale routes need to be maintained.
You can also configure the BGP long-lived graceful restarter mode negotiation mechanism for a particular address family instead of configuring this capability for all address families in a system, logical system, or routing instance.
When LLGR restarter is enabled or disabled for a family or the stale- time is changed, the session is reset so that the new capability can be sent to the neighbor.
The remaining statements are explained separately. See CLI Explorer.
