Description (Continued)
The value by which the keepalive timeout should be divided to give the
keepalive time, for example, the time interval, in seconds, between
LDP keepalive messages. LDP keepalive messages are sent to keep the
LDP session from timing out when no other LDP traffic is being sent
between the neighbors.
The hello time, also known as hold time. It is the time interval, in sec-
onds, that LDP waits before declaring a neighbor to be down. Hello
timeout is local to the system and is sent in the hello messages to a
neighbor.
The value by which the hello timeout should be divided to give the
hello time, for example, the time interval, in seconds, between LDP
hello messages. LDP uses hello messages to discover neighbors and to
detect loss of connectivity with its neighbors.
Enabled — Authentication using MD5 message based digest proto-
col is enabled.
Disabled — No authentication is used.
inService — The LDP is administratively enabled.
outService — The LDP is administratively disabled.
False — LDP aggregates multiple prefixes into a single Forwarding
Equivalence Class (FEC) and advertises a single label for the FEC.
This value is only applicable to LDP interfaces and not for targeted
sessions.
True — LDP de-aggregates prefixes into multiple FECs.
The Propagate Policy value specifies whether the LSR should generate
FECs and which FECs it should generate.
system — LDP will distribute label bindings only for the router's
system IP address.
interface — LDP will distribute label bindings for all LDP inter-
faces.
all — LDP will distribute label bindings for all prefixes in the rout-
ing table.
none — LDP will not distribute any label bindings.
interface — The interface's IP address is used to set up the LDP
session between neighbors. If multiple interfaces exist between two
neighbors, the 'interface' mode cannot be used since only one LDP ses-
sion is actually set up between the two neighbors.
system — The system's IP address is used to set up the LDP session
between neighbors.
