Ospf Challange Lab Noter

Hvis man skal lave en restribute mellem OSPF og EIGRP, skal man sætte en default metric på EIGRP siden. Kommandoen man skal bruge ser sådan ud:

router eigrp 65000
 redistribute ospf 1 metric 1000 10 255 255 1500

IS-IS Noter

IS-IS and OSPF are more similar than dissimilar. Both routing protocols have the following characteristics:

   * Open-standard link-state routing protocols
   * Support VLSM
   * Support route summarization between areas
   * Similar mechanisms to maintain the health of the LSDB (link-state advertisements [LSAs], link-state aging timers,
     and LSDB synchronization)
   * Use the shortest path first (SPF) algorithm, with similar update, decision, and flooding processes
   * Successful in the largest and most demanding ISP networks
   * Converge quickly after network changes
