• Disable OSPF. CONFIGURATION mode no ipv6 router ospf process-id} • Reset the OSPFv3 process. EXEC Privilege mode clear ipv6 ospf process Configuring the Cost of OSPFv3 Routes Change in bandwidth directly affects the cost of OSPF routes. • Explicitly specify the cost of sending a packet on an interface. INTERFACE mode ipv6 ospf interface-cost - interface-cost:The range is from 1 to 65535. Default cost is based on the bandwidth. • Specify how the OSPF interface cost is calculated based on the reference bandwidth method. The cost of an interface is calculated as Reference Bandwidth/Interface speed. ROUTER OSPFv3 auto-cost [reference-bandwidth ref-bw] To return to the default bandwidth or to assign cost based on the interface type, use the no auto-cost [referencebandwidth ref-bw] command. - ref-bw: The range is from 1 to 4294967. The default is 100 megabits per second. Configuring Stub Areas To configure IPv6 stub areas, use the following command. • Configure the area as a stub area. CONF-IPV6-ROUTER-OSPF mode area area-id stub [no-summary] - no-summary: use these keywords to prevent transmission in to the area of summary ASBR LSAs. - Area ID: a number or IP address assigned when creating the area. You can represent the area ID as a number from 0 to 65536 if you assign a dotted decimal format rather than an IP address. Configuring Passive-Interface To suppress the interface's participation on an OSPFv3 interface, use the following command. This command stops the router from sending updates on that interface. • Specify whether some or all some of the interfaces are passive. CONF-IPV6-ROUTER-OSPF mode passive-interface {type slot/port} Interface: identifies the specific interface that is passive. Open Shortest Path First (OSPFv2 and OSPFv3) 645
