MPLS Commands—BlackDiamond Switch Only
unconfigure mpls
unconfigure mpls [hello-hold-time | session-keep-alive-time]
Description
Restores the default values for hello-hold-time or session-keep-alive-time.
Syntax Description
Default
The default hello-hold-time is 15 seconds.
The default session-keep-alive-time is 40 seconds.
Usage Guidelines
This command can only be executed when MPLS is disabled.
The hello-hold-time is the amount of time, in seconds, an LSR maintains a record of the label space
requested by potential LDP peers. An LSR must receive an LDP hello packet at least hello-hold-time
seconds after the last hello packet was received, or the LSR concludes that the LDP peer has failed or no
longer wishes to label switch using the previously advertised label space.
The session-keep-alive-time specifies the minimum amount of time, in seconds, that an LSR must
receive an LDP PDU from an LDP peer to which it has an established LDP session. If an LDP PDU is
not received within the specified session-keep-alive-time since the reception of the last LDP PDU, the
LDP session is torn down.
Example
The following command restores the default values for hello-hold-time:
unconfigure mpls hello-hold-time
