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
The basic setup of IS-IS requires four steps.
- Step 1 Map out the areas, plan the addressing, and determine which interfaces are to participate in the IS-IS routing process.
- Step 2 Enable IS-IS on the router with the router isis global configuration command.
- Step 3 Configure the NET address with the net router configuration command.
- Step 4 Enable Integrated IS-IS on the appropriate interfaces with the ip router isis interface configuration command.
Commands to do this
router isis [area-tag] enable isis as an IP routing protocol and assigns a tag to the process (optional). Given en global configuration mode. net network-entity-title Identifies the router for isis by assigning a net to the router. Given in global configuration mode. Ip router isis [area-tag] enable isis on the interface that run isis (this approach is slightly different than most IP routing protocols, where the interface are defined by network statements; there is no network statement under the isis process.) Given in interface configuration mode.
