33.2.4 Troubleshooting

Faq: The routing protocol could not achieve the routing messages study under normal protocol running state
Troubleshooting: check following errors:
 Each node of route-map should at least has one node is permit match mode. When the route map is
used in routing messages filtering, the routing messages will be considered not pass the routing
messages filtering if certain routing messages does not pass the filtering of any nodes. When all nodes
are set to deny mode, all routing messages will not pass the filtering in this route-map.
 Items in address prefix list should at least have one item set to permit mode. The deny mode items can
be defined first to fast remove the unmatched routing messages, however if all the items are set to
deny mode, any route will not be able to pass the filtering of this address prefix list. We can define a
permit 0.0.0.0/0 le 32 item aft er several deny mode items are defined so to permit all other routing
messages pass through. Only default route will be matched in less-equal 32 is not specified.
