    Release Information

    Statement introduced in Junos OS Mobility Release 11.2W.

    Description

    Configure the options for the anchor Packet Forwarding Engine redundancy. The redundancy options are configured at the level of the Flexible PIC Concentrator (FPC). The FPCs that are configured for redundancy must be of the same type—that is, they must have the same number of Packet Forwarding Engines and the same forwarding capabilities.

    The type of redundancy supported is many-to-one (N:1), which means that one Packet Forwarding Engine acts as the backup for one or more (N) Packet Forwarding Engines. When you configure FPCs for anchor Packet Forwarding Engine redundancy, the corresponding anchor Packet Forwarding Engines in each FPC are configured for N:1 redundancy. The first Packet Forwarding Engine of each primary FPC is backed up by the first Packet Forwarding Engine of the backup FPC, the second Packet Forwarding Engine of each primary FPC is backed up by the second Packet Forwarding Engine of the backup FPC, and so on.

    For example, consider the case when you configure three FPCs—FPC1, FPC2, and FPC3—for redundancy with FPC1 and FPC2 as primary members, and FPC3 as backup. If each FPC has two Packet Forwarding Engines (PFE0 and PFE1), then FPC1-PFE0 and FPC2-PFE0 are backed up by FPC3-PFE0. Similarly, FPC1-PFE1 and FPC2-PFE1 are backed up by FPC3-PFE1.

    The remaining statements are explained separately.
