36.20 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 Configuration 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.
Example:
Switch#config terminal
Switch(config)#interface vlan 1
Switch(Config-if-Vlan1)#ipv6 ospf priority 0
