config>service>vprn>ospf>area>sham-link
Description
This command configures the interval between OSPF hellos issued on the interface, virtual link, or
sham-link.
The hello interval, in combination with the dead-interval, is used to establish and maintain the
adjacency. Use this parameter to edit the frequency that hello packets are sent.
Reducing the interval, in combination with an appropriate reduction in the associated dead-interval,
allows for faster detection of link and/or router failures at the cost of higher processing costs.
The no form of this command reverts to the default value.
Default
hello-interval 10 — A 10-second hello interval.
Special Cases OSPF Interface — If the hello-interval configured applies to an interface, then all nodes on the
subnet must have the same hello interval.
Virtual Link — If the hello-interval configured applies to a virtual link, then the interval on both
termination points of the virtual link must have the same hello interval.
Sham Link — If the hello-interval configured applies to a sham-link, then the interval on both
endpoints of the sham-link must have the same hello interval
Parameters
seconds — The hello interval in seconds expressed as a decimal integer.
interface-type
Syntax interface-type {broadcast | point-to-point}
no interface-type
Context config>service>vprn>ospf>area>interface
config>service>vprn>ospf3>area>interface
Description
This command configures the interface type to be either broadcast or point-to-point.
Use this command to set the interface type of an Ethernet link to point-to-point to avoid having to
carry the broadcast adjacency maintenance overhead if the Ethernet link provided the link is used as a
point-to-point.
If the interface type is not known at the time the interface is added to OSPF and subsequently the IP
interface is bound (or moved) to a different interface type, this command must be entered manually.
The no form of the command reverts to the default value.
Default point-to-point — If the physical interface is SONET.
