3.24.2.2.3 Interface Commands
interface
Syntax [no] interface ip-int-name
Context config>router>rsvp
Description This command enables RSVP-TE protocol support on an IP interface. No RSVP-TE
commands are executed on an IP interface where RSVP-TE is not enabled.
The no form of this command deletes all RSVP-TE commands such as hello-interval and
subscription, which are defined for the interface. The RSVP-TE interface must be shut down
before it can be deleted. If the interface is not shut down, the no interface ip-int-name
command does nothing except issue a warning message on the console indicating that the
interface is administratively up.
Parameters ip-int-name — specifies the network IP interface. The interface name cannot be in the
form of an IP address. Allowed values are 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.
Values 1 to 32 alphanumeric characters
auth-keychain
Syntax auth-keychain name
no auth-keychain
Context config>router>rsvp>interface
Description This command associates an authentication keychain with the RSVP-TE interface. The
keychain is a collection of keys used to authenticate RSVP-TE messages from remote peers.
The keychain allows the rollover of authentication keys during the lifetime of a session and
also supports stronger authentication algorithms than clear text and MD5.
The keychain must already be defined in the config>system>security>keychain context.
Either the authentication-key command or the auth-keychain command can be used by
RSVP-TE, but both cannot be supported at the same time. If both commands are configured,
the auth-keychain configuration will be applied and the authentication-key command will
be ignored.
By default, authentication is not enabled.
Default no auth-keychain
Parameters name — the name of an existing keychain, up to 32 characters
