EZB4009I

Explanation
 No Routing Information Protocol (RIP) packets
have been received from the NCP client to the destination destination in
the last timer_value minutes.  It is assumed that
the destination route is no longer active. Depending upon the timer_value,
one of the following actions is taken:  Value
Action
3
The route will have its metric changed to infinity for the next
2 minutes.  The metric change is necessary to alert adjacent routers
that the route to this destination is unreachable.  If NCPROUTE receives
any RIP packets for the NCP client from the destination router during
the 2 minute time interval, NCPROUTE will restore the route by changing
the metric to a valid one based upon the received RIP packet.  The
route will be deleted from the NCP client's routing table.
5
The route will be deleted from NCPROUTE's routing table for the
NCP client.

System action
 NCPROUTE continues.

Operator response
 None.

System programmer response
 These actions require the following
responses:  Value
Action
3
If the route was broadcasted for a while, and then suddenly stopped,
look for an adapter problem, or a problem with the physical line.
5
Examine the NCPROUTE trace output and determine when the broadcasting
has stopped for the route to the destination router.  If the route
to destination was only broadcast once in response
to the NCPROUTE's request for full route tables for the NCP client,
then the problem may be with the way RIP packets are broadcasted.

 In these cases, determine if NCPROUTE is receiving
the transport PDUs containing the RIP packets from the NCP client
by obtaining a MORETRACE IPUP trace and look for "discarding broadcast"
packet messages. This trace can confirm the lack of traffic on the
interface used for the transport PDUs forwarded by the NCP client.
 If this is not the case, then determine if NCPROUTE is receiving
the RIP packets over the NCP client's routing interface by obtain-
ing a NCP line trace.  See the NCP documentation for instructions
on obtaining a line trace.
