Description
Configure link group protection. This enables Packet Forwarding Engine-based local repair by pre-downloading suboptimal backup paths with appropriate weights in the Packet Forwarding Engine.
Options
| minimum-bandwidth rate | Minimum bandwidth to carry traffic. This is the minimum bandwidth at which the outgoing traffic can no longer be carried on this link group. When the bandwidth becomes less than or equal to this bandwidth, traffic will get load-balanced between primary and backup path.
|
| revert-bandwidth rate | Revert bandwidth to carry traffic. This is the bandwidth above which the outgoing traffic can be carried over the members of this link group. There is no need for the Packet Forwarding Engine to load-balance across member links of other suboptimal link groups if it provides a path with the shortest metric.
