Assigning OSPFv3 Process ID and Router ID to a VRF
To assign, disable, or reset OSPFv3 on a non-default VRF, use the following commands.
• Enable the OSPFv3 process on a non-default VRF and enter OSPFv3 mode.
CONFIGURATION mode
ipv6 router ospf {process ID}}
The process ID range is from 0 to 65535.
• Assign the router ID for this OSPFv3 process.
CONF-IPV6-ROUTER-OSPF mode
router-id {number}
• number: the IPv4 address.
The format is A.B.C.D.
NOTE:
Enter the router-id for an OSPFv3 router as an IPv4 IP address.
• Disable OSPF.
CONFIGURATION mode
no ipv6 router ospf process-id vrf {vrf-name}
• Reset the OSPFv3 process.
EXEC Privilege mode
clear ipv6 ospf [vrf vrf-name] process
Applying cost for OSPFv3
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 [reference-
bandwidth 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.
