Users Guide

Enable OSPFv3 for IPv6 by specifying an OSPF process ID and an area in INTERFACE mode. If you have not created an OSPFv3 process,
it is created automatically. All IPv6 addresses congured on the interface are included in the specied OSPF process.
NOTE: IPv6 and OSPFv3 do not support Multi-Process OSPF. You can only enable a single OSPFv3 process.
Set the time interval between when the switch receives a topology change and starts a shortest path rst (SPF) calculation.

Enabling IPv6 Unicast Routing
To enable IPv6 unicast routing, use the following command.
• Enable IPv6 unicast routing globally.
CONFIGURATION mode

Applying cost for OSPFv3
Change in bandwidth directly aects 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.
Assigning IPv6 Addresses on an Interface
To assign IPv6 addresses to an interface, use the following commands.
1 Assign an IPv6 address to the interface.
