MD5 Key Settings

This window allows the entry of a 16-character Message Digest − version 5 (MD5) key that can be used to authenticate every
packet exchanged between OSPF routers. It is used as a security mechanism to limit the exchange of network topology
information to the OSPF routing domain. MD5 Keys created here can be used in the OSPF windows below.
To configure an MD5 Key, click L3 Features > MD5 Key Settings to open the following window:
The following fields can be set:
Parameter Description
xStack DGS-3600 Series Layer 3 Gigabit Ethernet Managed Switch
This time represents the validity of this interface to be the default router for the link-local
network. A value of 0 represents that this Switch should not be recognized as the default
router for this link-local network. The user may set a time between 0 and 9000 seconds
with a default setting of 1800 seconds.
This field will set the time that remote IPv6 nodes are considered reachable. In essence,
this is the Neighbor Unreachability Detection field once confirmation of the access to this
node has been made. The user may set a time between 0 and 36000000 milliseconds
with a default setting of 1200000 milliseconds. A very low value is not recommended.
Used to set an interval time between 0 and 4294967295 milliseconds for the dispatch of
router advertisements by this interface over the link-local network, in response to a
Neighbor Solicitation message. If this Switch is set as the default router for this local link,
this value should not exceed the value stated in the Life Time field previously mentioned.
Setting this field to zero will specify that this switch will not specify the Retransmit Time
for the link-local network. (and therefore will be specified by another router on the link-
local network. The default value is 0 milliseconds.
Use the pull-down menu to enable or disable the Managed flag. When enabled, this will
trigger the router to use a stateful autoconfiguration process to get both Global and link-
local IPv6 addresses for the Switch. The default setting is Disabled.
Use the pull-down menu to enable or disable the Managed flag. When enabled, this will
trigger the router to use a stateful autoconfiguration process to get configuration
information that is not address information, yet is important to the IPv6 settings of the
Switch. The default setting is Disabled.
Used to set the maximum interval time between the dispatch of router advertisements by
this interface over the link-local network. This entry must be no less than 4 seconds (4000
milliseconds) and no more than 1800 seconds. The user may configure a time between 4
and 1800 seconds with a default setting of 600 seconds.
Used to set the minimum interval time between the dispatch of router advertisements by
this interface over the link-local network. This entry must be no less then 3 seconds and
no more than .75 (3/4) of the MaxRtrAdvInterval. The user may configure a time between
3 and 1350 seconds with a default setting of 198 seconds.
