the BGP route. Thus, either the LDP FEC or the BGP label route is active at any given time. The
impact of this is that the tunnel table needs to be re-programmed each time a route is deactivated and
the other is activated. Furthermore, the SDP revert-time cannot be used since there is no situation
where both LSP types are active for the same /32 prefix.
The no form of this command disables the mixed-LSP mode of operation. The user first has to
remove one of the LSP types from the SDP configuration or the command will fail.
Default no mixed-lsp-mode
revert-time
Syntax revert-time {revert-time | infinite}
no revert-time
Context config>service>sdp>mixed-lsp-mode
Description This command configures the delay period the SDP must wait before it reverts to a higher priority
LSP type when one becomes available.
The no form of the command resets the timer to the default value of 0. This means the SDP reverts
immediately to a higher priority LSP type when one becomes available.
Default 0
Parameters revert-time — Specifies the delay period, in seconds, that the SDP must wait before it reverts to a
higher priority LSP type when one becomes available. A value of zero means the SDP reverts
immediately to a higher priority LSP type when one becomes available.
Values 0 — 600
infinite — This keyword forces the SDP to never revert to another higher priority LSP type unless the
currently active LSP type is down.
ldp
Syntax [no] ldp
Context config>service>sdp
Description This command enables LDP-signaled LSP's on MPLS-encapsulated SDPs.
In MPLS SDP configurations either one LSP can be specified or LDP can be enabled. The SDP ldp
and lsp commands are mutually exclusive. If an LSP is specified on an MPLS SDP, then LDP cannot
be enabled on the SDP. To enable LDP on the SDP when an LSP is already specified, the LSP must be
removed from the configuration using the no lsp lsp-name command.
Alternatively, if LDP is already enabled on an MPLS SDP, then an LSP cannot be specified on the
SDP. To specify an LSP on the SDP, the LDP must be disabled. The LSP must have already been
created in the config>router>mpls context with a valid far-end IP address. The above rules are
relaxed when the mixed-lsp option is enabled on the SDP.
Default no ldp (disabled)
