Description
This command creates a context to configure an OSPF interface.
By default interfaces are not activated in any interior gateway protocol such as OSPF unless explicitly
configured.
The no form of the command deletes the OSPF interface configuration for this interface. The
shutdown command in the config>router>ospf>interface context can be used to disable an interface
without removing the configuration for the interface.
Default
no interface — No OSPF interfaces are defined.
Parameters
ip-int-name — The IP interface name. Interface names must be unique within the group of defined IP
advertise-subnet
Syntax [no] advertise-subnet
Context config>service>vprn>ospf>area>interface
Description
This command enables advertising point-to-point interfaces as subnet routes (network number and
mask). When disabled, point-to-point interfaces are advertised as host routes.
The no form of the command disables advertising point-to-point interfaces as subnet routes meaning
they are advertised as host routes.
Default
advertise-subnet — Advertises point-to-point interfaces as subnet routes.
authentication-key
Syntax authentication-key [authentication-key | hash-key] [hash | hash2]
no authentication-key
Context config>service>vprn>ospf>area>interface
config>service>vprn>ospf>area>virtual-link
Description
This command configures the password used by the OSPF interface or virtual-link to send and
receive OSPF protocol packets on the interface when simple password authentication is configured.
All neighboring routers must use the same type of authentication and password for proper protocol
communication. If the authentication-type is configured as password, then this key must be
configured.
By default, no authentication key is configured.
The no form of the command removes the authentication key.
Default
no authentication-key - No authentication key is defined.
7750 SR OS Services Guide
interfaces for config router interface and config service vprn interface commands. An
interface name cannot be in the form of an IP address. Interface names can be any string up to 32
characters long composed of printable, 7-bit ASCII characters. If the string contains special
characters (#, $, spaces, etc.), the entire string must be enclosed within double quotes.
If the IP interface name does not exist or does not have an IP address configured an error
message will be returned.
If the IP interface exists in a different area it will be moved to this area.
