Hello Fctr |
The value by which the hello timeout should be divided to give the hello time; that is, 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. |
Hold Time |
The time interval, in seconds, that LDP waits before declaring a neighbor to be down. Hold time (also known as Hello time) is local to the system and is sent in the hello messages to a neighbor. |
KA Fctr |
The value by which the keepalive timeout should be divided to give the keepalive time; that is, 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. |
KA Time |
The time interval, in seconds, that LDP waits before tearing down a session. If no LDP messages are exchanged during this time interval, the LDP session is torn down. Generally the value is configured to be three times the keepalive time (the time interval between successive LDP keepalive messages). |

IPv4 Interface Parameters IPv6 Interface Parameters |
|
Keepalive Timeout |
The time interval, in seconds, that LDP waits before tearing down a session. If no LDP messages are exchanged during this time interval, the LDP session is torn down. Generally the value is configured to be three times the keepalive time (the time interval between successive LDP keepalive messages). |
Keepalive Factor |
The value by which the keepalive timeout should be divided to give the keepalive time; that is, 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. |
Hold Time |
The time interval, in seconds, that LDP waits before declaring a neighbor to be down. Hold time (also known as Hello time) is local to the system and is sent in the hello messages to a neighbor. |
Hello Factor |
The value by which the hello timeout should be divided to give the hello time; that is, 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. |
Propagate Policy |
Specifies whether the LSR should generate FECs and which FECs it should generate |
system — indicates that the LDP distributes label bindings only for the router’s system IP address |
|
interface — indicates that the LDP distributes label bindings for all LDP interfaces |
|
all — indicates that the LDP distributes label bindings for all prefixes in the routing table |
|
none — indicates that the LDP does not distribute any label bindings |
|
Transport Address |
interface — the interface 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 because only one LDP session is actually set up between the two neighbors. |
system — the system IP address is used to set up the LDP session between neighbors |
|
Label-Distribution |
The label distribution method |
Label-Retention |
liberal — all advertised label mappings are retained whether they are from a valid next hop or not. 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 true next hop, the label received earlier is then used. |
conservative — advertised label mappings are retained only if they are 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. |
|
Control Mode |
ordered — 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 |
independent — 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 |
|
Route Preference |
The route preference assigned to LDP routes. When multiple routes are available to a destination, the route with the lowest preference is used. This value is only applicable to LDP interfaces and not for targeted sessions. |
IPv4 Targeted Session Parameters IPv6 Targeted Session Parameters |
|
Keepalive Timeout |
The factor used to derive the keepalive interval |
Keepalive Factor |
The time interval, in seconds, that LDP waits before tearing down the session |
Hold Time |
The time left before a neighbor is declared to be down |
Hello Factor |
The value by which the hello timeout should be divided to give the hello time; that is, 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. |
Disable — indicates that no authentication is being used |
|
Passive Mode |
True — indicates that LDP responds only when it gets a connect request from a peer and does not attempt to actively connect to its neighbors |
False — indicates that LDP actively tries to connect to its peers |
|
Targeted Sessions |
Enabled — indicates that targeted sessions are enabled |
Disabled — indicates that targeted sessions are disabled |

Label |
Description |
|---|---|
Peer |
The IP address of the peer |
Adm |
Up — indicates that LDP is administratively enabled |
Down — indicates that LDP is administratively disabled |
|
Opr |
Up — indicates that LDP is operationally enabled |
Down — indicates that LDP is operationally disabled |
|
Hello Factor |
The value by which the hello timeout should be divided to give the hello time; that is, 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. |
Hold Time |
The time interval, in seconds, that LDP waits before declaring a neighbor to be down. Hold time (also known as Hello time) is local to the system and is sent in the hello messages to a neighbor. |
Keepalive Factor |
The value by which the keepalive timeout should be divided to give the keepalive time; that is, 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. |
Keepalive Timeout |
The time interval, in seconds, that LDP waits before tearing down a session. If no LDP messages are exchanged during this time interval, the LDP session is torn down. Generally the value is configured to be three times the keepalive time (the time interval between successive LDP keepalive messages). |
Passive Mode |
The mode used to set up LDP sessions. This value is only applicable to targeted sessions and not to LDP interfaces. This mode is always set to False. |
True — indicates that LDP responds only when it gets a connect request from a peer and does not attempt to actively connect to its neighbors |
|
False — indicates that LDP actively tries to connect to its peers |
|
Auto Create |
Specifies whether a targeted peer was automatically created through a Service Manager. For an LDP interface, this value is always false. |
No. of Peers |
The total number of LDP peers |
LSP |
The LSP name |

This command displays information about the TCP transport session of an LDP peer.
displays either IPv4 or IPv6 LDP session information
specifies the authentication keychain name up to 32 characters in length
specifies the IP address of the transport peer
The following output is an example of TCP session parameter information.
