2.7.345 ROUTE-OVERFLOW
The ROUTE-OVERFLOW indicates the condition when the OSPF routing table exceeds 700 routes. The
symptoms for this condition are loss of visibility to a node or network, inability to access a node using
CTC, CTM, Telnet, Ping, and so on.
Clear the ROUTE-OVERFLOW Condition
Reconfigure the OSPF network to less than 700 routes.

2.7.346 RPR-PASSTHR
The IEEE 802.17 b-based RPR Interface in Pass-Through Mode condition indicates that an ML card's
IEEE 802.17 b-based RPR interface is not participating in a ring. Instead, the card is behaving like a
passive device that allows the signal to transit but does not manipulate it. Pass-through mode itself is
hitless.
You can manually place an ML card into (or out of) pass-through mode using the Cisco IOS CLI
command SHUTDOWN (SHUT) for such reasons as adding, removing, or servicing the node. To do so
is hitless.
The ML-1000 automatically enters pass-through mode if either of the following conditions is true:

For GFP and HDLC mode, the ML card shutdown (SHUT) command causes an
