VPRN Service Configuration Commands
Context config>service>vprn>ospf>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.
broadcast — If the physical interface is Ethernet or unknown.
Special Cases Virtual-Link — A virtual link is always regarded as a point-to-point interface and not configurable.
Parameters
broadcast — Configures the interface to maintain this link as a broadcast network. To significantly
point-to-point — Configures the interface to maintain this link as a point-to-point link.

Context config>service>vprn>ospf>area>interface
config>service>vprn>ospf>area>virtual-link
Description
This command configures a message digest key when MD5 authentication is enabled on the interface.
Multiple message digest keys can be configured.
The no form of the command removes the message digest key identified by the key-id.
Default
No message digest keys are defined.
Parameters
keyid — The keyid is expressed as a decimal integer.
md5 key — The MD5 key. The key can be any alphanumeric string up to 16 characters in length.
md5 hash-key — The MD5 hash key. The key can be any combination of ASCII characters up to 32
hash — Specifies the key is entered in an encrypted form. If the hash parameter is not used, the key

to-point if only two routers are connected, even if the network is a broadcast media such as
Ethernet.
Values

quotation marks (" ").
This is useful when a user must configure the parameter, but, for security purposes, the actual
unencrypted key value is not provided.
is assumed to be in a non-encrypted, clear text form. For security, all keys are stored in encrypted
form in the configuration file with the hash parameter specified.
