Description (partial)

<Symptoms:<B/> There is a mismatch of the BPI index between the cable line card and the remote SPA.

Conditions:<B/> This issue is seen when a line card is running with no redundancy, and the guardian line card is rebooted. When the guardian line card is restarted, the unique indexes that are used to program the SPA are lost and are overwritten by new modems coming online. Two modems now share the same SPA keying index, and either one of these modems can become Layer 3 unreachable, depending on when the keys are written to the SPA.
