Switch(config)#ipv6 ospf display route single-line
13.7.3.10 ipv6 ospf hello-interval
Command: ipv6 ospf hello-interval <time> [instance-id <id>]
no ipv6 ospf hello-interval [instance-id <id>]
Function: Specify the hello-interval on the interface; the "no ipv6 ospf hello-interval
[instance-id <id>]" restores the default value
Parameter: <id> is the interface instance ID, ranging between 0~255, defaulted at 0
<time > is the length of the adjacent layer 3 switch, in seconds, ranging between 1～
65535
Default: Default HELLO packet sending interval is 10 seconds.
Command Mode: Interface Mode
Usage Guide: HELLO data packet is the most common packet which is periodically sent
to adjacent layer 3 switch to discover and maintain adjacent relationship, elect DR and
BDR. The user set hello-interval value will be written into the HELLO packet and
transmitted. The less the hello-interval value is, the sooner the network topological
structure is discovered as well larger the cost. The ensure the normal operation of OSPF
protocol the hello-interval parameter between the layer 3 switches adjacent to the
interface must be in accordance. The command can configure on IPv6 tunnel interface,
but it is successful configuration to only configure tunnel carefully.
Example:
Switch#config terminal
Switch(config)#interface vlan 1
Switch(Config-if-Vlan1)#ipv6 ospf hello-interval 20
13.7.3.11 ipv6 ospf priority
Command: ipv6 ospf priority <priority> [instance-id <id>]
no ipv6 ospf priority[instance-id <id>]
Function: Configure the priority when electing "Defined layer 3 switch" at the interface.
The "no ipv6 ospf [<ip-address>] priority" command restores the default value
Parameter: <id> is the interface instance ID, ranging between 0~255, and defaulted at
0<priority> is the priority of which the valid value ranges between 0～255.
Default: The default priority when electing DR is 1.
Command Mode: Interface Mode
Usage Guide: When two layer 3 switches connected to the same segments both want to
be the "Defined layer 3 switch", the priority will decide which one should be chosen.
Normally the one with higher priority will be elected, or the one with larger router-id
number if the priorities are the same. A layer 3 switch with a priority equal to 0 will not be
