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
