If you need to enable loop detection, configure this command before LDP is enabled on all interfaces. Its value, which depends on actual networking, determines the loop detection speed during LSP creation

Related commands: mpls ldp loop-detect, mpls ldp path-vector.

Examples

# Set the maximum hop count of loop detection to 22.


[Quidway] mpls ldp hops-count 22



1-23

# Set the maximum hop count of loop detection to its default value 32.

1.2.12 mpls ldp loop-detect

Syntax

mpls ldp loop-detect

undo mpls ldp loop-detect

View

System view

Parameters

None

Description

Use the mpls ldp loop-detect command to enable loop detection.

Use the undo mpls ldp loop-detect command to disable loop detection.

By default, loop detection is not enabled in the system.

If you need to enable loop detection, configure this command before LDP is enabled on any interface.

Related commands: mpls ldp hops-count, mpls ldp path-vectors.

Note:

To make the loop detection take effect, you need to perform the same loop detection configurations on all devices in the same MPLS domain. If not, two neighboring sides with different loop detection configurations cannot establish the LDP session. This is because before the LDP initiates a session establishment, it checks whether the two sides have the same loop detection configurations.

Examples

# Enable loop detection.


[Quidway] mpls ldp loop-detect

# Disable loop detection.

[Quidway] undo mpls ldp loop-detect

1.2.19 mpls ldp timer

Syntax

In VLAN interface view:

mpls ldp timer { session-hold session-holdtime | hello hello-holdtime }

undo mpls ldp timer { session-hold | hello }

In remote-peer view:

mpls ldp timer { targeted-session-hold | targeted-hello } { holdtime holdtime | interval interval }

undo mpls ldp timer { targeted-session-hold | targeted-hello } { holdtime | interval }

View

VLAN interface view, remote-peer view



1-29

Parameters

hello hello-holdtime: Specifies the hold time (i.e. timeout time) of the Hello hold timer, in the range of 6 to 65535 (seconds). By default it is 15 seconds.

session-hold session-holdtime: Specifies the time interval for Session hold timer to send a session packet, in the range of 1 to 65535 (seconds). By default it is 60 seconds.

targeted-hello: Specifies the hold time (i.e. timeout time) of the Targeted-hello hold timer, in the range of 1 to 65535 (seconds). By default holdtime is 45 seconds and interval is 13 seconds.

targeted-session-hold: Specifies the time interval for Targeted-session hold timer to send a session packet, in the range of 1 to 65535 (seconds). By default holdtime is 60 seconds and interval is 24 seconds.

holdtime: Time interval for the hold timer.

interval: Time interval to send a Keepalive packet.

Description

Use the mpls ldp timer command to set the hold time for the Hello hold timer and Session hold timer.

Use the undo mpls ldp timer command to restore the default values.

The timeout of the Hello hold timer means that the adjacency with the peer goes down; the timeout of the Session hold timer means the session with the peer goes down.

targeted-hello interval refers to the time interval to send a targeted-hello packet. It cannot be greater than (targeted-hello holdtime) × 0.3, so the maximum value is 65535 × 0.3 = 19660.5.

targeted-session-hold interval refers to the time interval to send a Keepalive packet. It cannot be greater than (targeted-session-hold holdtime) × 0.4.

In general, the time interval to send a hello/keepalive packet is one third of the hold time of Hello/Session hold timer.

You can usually use the default values if not in special cases, Note that you must reset the session to validate new values if you do modify these timer parameters.

Related commands: mpls ldp, mpls ldp enable.

Examples

# Modify the hold time of the Hello timer to 30 seconds.



[Quidway-Vlan-interface201] mpls ldp timer hello 30




1.2.20 mpls ldp transport-ip

Syntax

mpls ldp transport-ip { interface | ip-address }

undo mpls ldp transport-ip

View

VLAN interface

Parameters

interface: Sets the IP address of the current interface as the transport address.

ip-address: Sets the IP address as the transport address.

Description

Use the mpls ldp transport-ip command to configure an LDP transport address.

Use the undo mpls ldp transport-ip command to restore the default LDP transport address.

By default, LSR ID is set as a transport address.

When there are multiple directly-connected and MPLS LDP-enabled links between two LSR neighbors, all these links must be configured with the same transport address (it is recommended to adopt the default LSR ID as the transport address). Otherwise, the system may be unable to set up a steady LDP session.

For a Remote-peer, the transport address cannot be configured and is fixed to the LSR ID.

By default, an LSR ID is the address of some Loopback interface and the Remote peer can route to this address for a session. For a Local peer, the address of the local interface or the Router ID of LSR can be adopted as its transport address.

Examples

# Set the address of the current interface as a transport address.



[Quidway-Vlan-interface201] mpls ldp transport-ip interface

# Set the address of another interface as a transport address.

[Quidway-Vlan-interface201] mpls ldp transport-ip 10.1.11.2

1.2.21 remote-ip

Syntax

remote-ip remoteip

View

remote-peer view

Parameters

remoteip: IP address of the Remote-peer.

Description

Use the remote-ip command to configure a Remote-IP address. The address should be the lsr-id of the remote LSR. As Remote Peers adopt LSR ID as their transport addresses, the last two Remote Peers use the lsr-id as their transport addresses for creating TCP connection.

Related commands: mpls ldp remote-peer.

Examples

# Configure the address of remote-peer.


[Quidway] mpls ldp remote-peer 12
