SR-MPLS commands

bfd detect-multiplier

Use bfd detect-multiplier to set the BFD detection time multiplier for SRLSPs.

Use undo bfd detect-multiplier to restore the default.

Syntax

bfd detect-multiplier value

undo bfd detect-multiplier

Default

The BFD detection time multiplier is not set for SRLSPs. The BFD detection time multiplier set by the

bfd multi-hop detect-multiplier command applies.

Views

Segment Routing view

Predefined user roles

network-admin

Parameters

value: Specifies a detection time multiplier, which is the maximum number of consecutive BFD

packets that can be discarded. The value range for this argument is 3 to 50.

Usage guidelines

The device sends BFD packets to a peer periodically. If the device does not receive BFD packets

from the peer within the actual detection interval, it determines that the session is down. The actual

detection interval of the sender is the detection time multiplier of the receiver × the actual sending

interval of the receiver.

This command takes effect only on BFD sessions created by the bfd enable command.

Examples

# Set the BFD detection time multiplier to 3 for SRLSPs.

bfd enable

Use bfd enable to enable BFD for SRLSPs.

Use undo bfd enable to restore the default.

Syntax

bfd enable [ prefix-list prefix-list-name ] [ echo | nil-fec ]

2

undo bfd enable

Default

BFD for SRLSPs is not enabled.

Views

Segment routing view

Predefined user roles

network-admin

Parameters

prefix-list prefix-list-name: Specifies an IPv4 prefix list by the prefix list name, a

case-sensitive string of 1 to 63 characters. The device can create BFD sessions only for the SRLSPs

permitted by the specified IPv4 prefix list. If you do not specify an IPv4 prefix list, the device can

create BFD sessions for all SRLSPs.

echo: Specifies the BFD echo packet mode. If you do not specify this keyword, the BFD control

packet mode is used to verify SRLSP connectivity.

nil-fec: Encapsulates the Nil FEC in MPLS echo request packets when BFD control packet mode

is used to detect SRLSPs. In SR to LDP interworking mode, the ingress node (source node) cannot

determine whether the LDP LSP is connected to the SRLSP. When the ingress node uses MPLS

BFD to detect LSPs, it encapsulates LDP FEC in MPLS echo request packets, which will fail the FEC

type verification on the egress node (end-point node). Then, the BFD session will go down. To

resolve this issue, specify the nil-fec keyword to enable the ingress node to encapsulate the Nil

FEC in MPLS echo request packets. The egress node will not check the FEC type of packets

encapsulated with the Nil FEC.

Usage guidelines

This command enables the device to create a BFD session for each primary SRLSP to verify the

connectivity of the primary SRLSP. When a primary SRLSP fails, BFD can quickly detect the failure

and switches traffic to the backup SRLSP to reduce packet loss.

Before you execute this command, enable MPLS BFD by using the mpls bfd enable command.

If you execute both the bfd enable command and the mpls bfd command for SRLSPs, the mpls

bfd command takes effect on the SRLSPs.

Examples

# Enable BFD for SRLSPs.

bfd min-echo-receive-interval

Use bfd min-echo-receive-interval to set the minimum interval for receiving BFD echo

packets for SRLSP BFD.

Use undo bfd min-echo-receive-interval to restore the default.

3

Syntax

bfd min-echo-receive-interval interval

undo bfd min-echo-receive-interval

Default

The minimum interval for receiving BFD echo packets is not set for SRLSP BFD. The interval set by

the bfd multi-hop min-echo-receive-interval command applies.

Views

Segment routing view

Predefined user roles

network-admin

Parameters

interval: Specifies the minimum interval for receiving BFD echo packets, in milliseconds. The

value range for this argument is 3 to 10000.

Usage guidelines

The interval for receiving BFD echo packets is also the interval for sending BFD echo packets. By

executing this command, you can control both the receiving interval and sending interval for BFD

echo packets.

This command takes effect only on the echo mode BFD sessions created by the bfd enable

command.

Examples

# Set the minimum BFD echo packet receiving interval for SRLSP BFD to 450 milliseconds.

undo bfd min-receive-interval

Default

The minimum interval for receiving BFD packets is not set for SRLSP BFD. The interval set by the

bfd multi-hop min-receive-interval command applies.

Parameters

interval: Specifies the minimum interval for receiving BFD packets, in milliseconds. The value

range for this argument is 3 to 10000.

Usage guidelines

Use this command to prevent the packet sending rate of the peer end from exceeding the packet

receiving rate of the local end. If the receiving rate is exceeded, the peer end dynamically adjusts the

BFD packet transmitting interval to the minimum receiving interval of the local end.

This command takes effect only on BFD sessions created by the bfd enable command.

Examples

# Set the minimum BFD packet receiving interval for SRLSP BFD to 550 milliseconds.

Parameters

interval: Specifies the minimum interval for transmitting BFD packets, in milliseconds. The value

range is 3 to 10000.

Usage guidelines

Use this command to prevent the BFD packet sending rate from exceeding the packet receiving rate

of the peer end.

The actual BFD packet transmitting interval on the local end is the greater value between the

following values:

5

•

Minimum interval for transmitting BFD packets on the local end.

•

Minimum interval for receiving BFD packets on the peer end.

This command takes effect only on BFD sessions created by the bfd enable command.
