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 configured on the interface are included in the specified OSPF process.

IPv6 and OSPFv3 do not support Multi-Process OSPF. You can only enable a single OSPFv3 process. To create multiple

OSPF processes you need to have multiple VRFs on a switch.

Set the time interval between when the switch receives a topology change and starts a shortest path first (SPF) calculation.

timers spf delay holdtime

To set the interval time between the reception of topology changes and calculation of SPF in milli seconds, use the

timers spf delay holdtime msec command.

Dell(conf)#ipv6 router ospf 1

Dell(conf-ipv6-router_ospf)#timer spf 2 5 msec

Dell(conf-ipv6-router_ospf)#

Dell(conf-ipv6-router_ospf)#show config

timers spf 2 5 msec

Enabling IPv6 Unicast Routing

To enable IPv6 unicast routing, use the following command.

Enable IPv6 unicast routing globally.

CONFIGURATION mode

ipv6 unicast routing

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.
