14.7.3.11 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
14.7.3.12 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
