PLANET XGS3-24040 - Manual (Page 471)

33-184
Function:
Configure the priority when electing “Defined layer 3 switch” at the interface. The “no ip ospf
[<ip-address>] priority” command restores the default value.
Parameter:
<ip-address> is the interface IP address show in dotted decimal notation.
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”.
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)#ip ospf priority 0

Command:
ip ospf [<ip-address>] retransmit-interval
no ip ospf [<ip-address>] retransmit-interval
Function:
Specify the retransmit interval of link state announcements between the interface and adjacent layer
3 switches. The “no ip ospf [<ip-address>] retransmit-interval” command restores the default
value.
Parameter:
<ip-address> is the interface IP address show in dotted decimal notation.
<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.
