Issue/Introduction
Design Decision: Do not enable Graceful Restart between BGP neighbors.
Resolution
Design Justification: Avoids loss of traffic.
On the Tier-0 gateway, BGP peers from all the gateways are always active. On a failover, the Graceful Restart capability increases the time a remote neighbor takes to select an alternate Tier-0 gateway. As a result, BFD- based convergence is delayed.
Design Implication: None.
This design decision is supported in the following Domains.
• Management Domain
• VI Workload Domain
This design decision is supported on VVD version 5.0 and higher.
