Switch(Config-if-Vlan1)#ipv6 ospf hello-interval 20

Relevant Commands: ipv6 ospf dead-interval

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

elected as “Defined layer 3 switch” or “Backup Defined layer 3 switch”. The command

can configure on IPv6 tunnel interface, but it is successful configuration to only configure

tunnel carefully.

Example:

Configure the priority of DR electing. Configure the interface vlan 1 to no

election right, namely set the priority to 0.

Switch#config terminal

Switch(config)#interface vlan 1

Switch(Config-if-Vlan1)#ipv6 ospf priority 0

13.7.3.12 ipv6 ospf retransmit-interval

Command: ipv6 ospf retransmit-interval

<time> [instance-id <id>]

no ipv6 ospf retransmit-interval [instance-id <id>]

Function:

Specify the retransmit interval of link state announcements between the

interface and adjacent layer 3 switches. The “no ipv6 ospf retransmit-interval

[instance-id <id>]

” command restores the default value

Parameter: <id>

is the interface instance ID, ranging between 0~255, defaulted at 0

<time>

is the retransmit interveral of link state announcements between the interface and

adjacent layer 3 switches, shown in seconds ang raning between 1~65535

Default:

Default retransmit interval is 5 seconds

Command Mode: Interface Mode

Usage Guide:

When a layer 3 switch transmits LSA to its neighbor, it will maintain the

link state announcements till confirm from the object side is received. If the confirm
