The type of advertised label mappings that the router will retain (lib-
eral or conservative).
The liberal value indicates that all advertised label mappings are
retained whether or not they are from a valid next hop. When the label
distribution value is downstream unsolicited, a router may receive label
bindings for the same destination for all its neighbors. Labels for the
non-next hops for the FECs are retained in the software but not used.
When a network topology change occurs where a non-next hop
becomes a valid next hop, the label received earlier is then used
The conservative value indicates that advertised label mappings are
retained only if they will be used to forward packets; for example if the
label came from a valid next hop. Label bindings received from non-
next hops for each FEC are discarded.
The response to label request (ordered or independent).
The ordered value indicates that label bindings are not distributed in
response to a label request until a label binding has been received from
the next hop for the destination
The independent value indicates that label bindings are distributed
immediately in response to a label request, even if a label binding has
not yet been received from the next hop for the destination
The status of loop detection for this router. This field displays one of
the following values:
•
Enabled—Loop detection is enabled.
•
Disabled—Loop detection is disabled.
•
None—Loop detection is not supported.
•
Other—Loop detection is supported by a method other than
hopCount, pathVector, or hopCountAndPathVector.
•
hopCount—Loop detection by hop count only.
•
pathVector—Loop detection by path vector only.
•
hopCountAndPathVector—Loop detection by hop count and
path vector.
The amount of time, in seconds, LDP waits to receive keepalive mes-
sages from an LDP peer before tearing down the session with that peer.
Configured through the configure router ldp interface-parameters
keepalive command.
The Keepalive factor value that is divided into the Keepalive Timeout
value to determine the interval at which Keepalive messages are sent
from this interface. Configured through the
interface-parameters keepalive
The Hold Time value (also referred to as Hello Timeout) determines
the amount of time, in seconds, LDP waits to receive hello messages
from a peer before declaring that the peer is down. Configured through
the configure router ldp interface-parameters hello
