no ipv6 ospf transmit-delay
[instance-id <0-255>]
Sets a transmit delay to the default value.
11.3.3.3 OSPFv3 Priority
Routers have each role to exchange the information on OSPFv3 network. DR
(Designated Router) is one of essential role to get and transmit the route information in
the same area. The router having the highest priority becomes DR (Designated Router). If
there are routers which have same priority, the highest router ID will be DR.
Normally, router has priority 1, but it can be changed to make DR through the
configuration of priority.
To configure a priority of OSPFv3 router, use the following command.
ipv6 ospf priority <0-255>
[instance-id <0-255>]
Configures a priority of OSPFv3 router.
To delete a configured priority of OSPFv3 router, use the following command.
no ipv6 ospf priority [instance-id
<0-255>]
Deletes a configured priority of OSPFv3 router.
11.3.3.4 OSPFv3 Network Type
There are 4 types of OSPFv3 network. Broadcast network, NBMA (Non-broadcast-
multiple-access) network, Point-to-multipoint network and Point-to-point network.
User can configure OSPFv3 network as a Broadcast network or Non-broadcast network
type. For example, if the network does not support multicasting it can be configured Non-
broadcast type from Broadcast type, and NBMA network as a Frame relay can be
broadcast network type.
NBMA type network need virtual circuit to connect routers. But Point-to-multipoint type
uses virtual circuit on part of network to save the management expenses. It does not to
need to configure Neighbor router to connect routers which are not directly connected. It
also saves IP resources and no need to configure the process for destination router. It
supports those benefits for stable network services.
Generally, the routers and Layer 3 switches are using Broadcast type network.
To select an OSPFv3 network type, use the following command.
ipv6 ospf network {broadcast | non-broadcast |
point-to-multipoint | point-to-point} [instance-
