The following tools could be deployed for managing core networks:

• For traffic management, the following tools could be deployed: MRTG, Cricket or Nagios
• Intermapper or Nagios can be deployed for monitoring and displaying equipment and link status.
• For routing management, two different tools can be deployed, which have completely different goals :
o ASpath-tree can be deployed to monitor the routing policy and the global status of the routing table.
o Home-made scripts have to be deployed for monitoring BGP peerings for two reasons. On one hand, very few routers have a MIB describing IPv6 BGP behaviour of the router. On the other hand, there are no clients available to perform the requests.
• For accounting management: IPflow can be used. But it appears that in most cases, network administrators prefer to deploy their own collector.
• Rancid for managing the configuration of the equipment
