Preface

The H3C MSR documentation set includes 17 command references, which describe the commands andcommand syntax options available for the H3C MSR Series Routers.

The MPLS Command Reference(V5) describes the MPLS configuration commands.

Command conventions

Convention Description

Boldface Bold text represents commands and keywords that you enter literally as shown.Italic Italictext represents arguments that you replace with actual values.

[ ] Square brackets enclose syntax choices (keywords or arguments) that are optional.

{ x | y | ... } Braces enclose a set of required syntax choices separated by vertical bars, from whichyou select one.

[ x | y | ... ] Square brackets enclose a set of optional syntax choices separated by vertical bars, fromwhich you select one or none.

{ x | y | ... } * Asterisk marked braces enclose a set of required syntax choices separated by verticalbars, from which you select at least one.

[ x | y | ... ] * Asterisk marked square brackets enclose optional syntax choices separated by verticalbars, from which you select one choice, multiple choices, or none.

&The argument or keyword and argument combination before the ampersand (&) sign canbe entered 1 to n times.

# A line that starts with a pound (#) sign is comments.

GUI conventions


BoldfaceWindow names, button names, field names, and menu items are in Boldface. Forexample, the New Userwindow appears; click OK.

Basic MPLS commands

Commands configured in MPLS LDP view apply to the public network and those configured in MPLS LDPVPN instance view apply to the MPLS VPN instance.

accept-labelUse accept-label to configure a label acceptance policy.

Use undo accept-label to restore the default.

Syntax

accept-label peerpeer-idip-prefix ip-prefix-name

undo accept-label peerpeer-id

Default

An LSR accepts all label bindings received from its LDP peers.

Views

MPLS LDP view, MPLS LDP VPN instance view

Default command level

2: System level

Parameters

peerpeer-id: Specifies an LDP peer. The peer-idargument is the LSR ID of the LDP peer.

ip-prefix ip-prefix-name: Specifies the IP prefix list to be used for filtering received FEC-label bindings. Theip-prefix-nameargument is the name of the IP prefix list, a string of 1 to 19 characters.

Usage guidelines

A label acceptance policy is for filtering the FEC-label bindings received. With such a policy configured,an upstream LSR filters the label bindings received from the specified downstream LSR by the specified IPprefix list, and accepts and saves only bindings with the FEC destinations permitted by the specified IPprefix list.

When the label acceptance control configuration on an LSR is changed (for example, the labelacceptance policy is deleted by using the undo accept-label command), you must execute the reset mplsldp command to reset LDP sessions so that the downstream LSR re-advertises its label bindings and theupstream LSR can obtain the label bindings not accepted before.

Examples

# Configure the device to accept only the label bindings of FECs with destination addresses on subnet10.1.1.0/24 and 10.2.1.0/24 from LDP peer 1.1.1.9.

advertise-labelUse advertise-label to configure a label advertisement policy.

Use undo advertise-label to restore the default.

Syntax

advertise-label ip-prefix ip-prefix-name[ peerpeer-ip-prefix-name]

undo advertise-label ip-prefix ip-prefix-name

Default

An LSR does not filter label bindings to be advertised.

Views

MPLS LDP view, MPLS LDP VPN instance viewDefault command level

2: System level

Parameters

ip-prefix ip-prefix-name: Specifies an IP prefix list to be used for filtering the label bindings to beadvertised. The ip-prefix-nameargument is the name of the IP prefix list, a string of 1 to 19 characters.

peerpeer-ip-prefix-name: Specifies a list of LDP peers. The peer-ip-prefix-nameargument is the IP prefixlist name, a string of 1 to 19 characters. If you do not specify the LDP peer list, the label advertisementpolicy is for all LDP peers.

Usage guidelinesWhen advertising label bindings to peers, an LSR follows these rules:

If the IP prefix of a label binding to be advertised fails the IP prefix checking, the LSR does notadvertise the label binding to any peer.

If the IP prefix of a label binding to be advertised passes the IP prefix checking and the peer list isnot specified, the LSR will advertise the label binding to all peers.

If the IP prefix of a label binding to be advertised passes the IP prefix checking and a peer list isspecified, the LSR will advertise the label binding to the peers that pass the peer list checking.

If the IP prefix of a label binding to be advertised passes the checking of more than one IP prefix lists(which are specified by executing the advertise-label command for multiple times), the LSR will

advertise the label binding based on the configuration by the first advertise-label command.

Examples

# Configure label advertisement control policies so that the device:

Advertises label bindings for FEC 10.1.1.0/24 to the LDP peer with the LSR ID 3.3.3.9 Advertises label bindings for FEC 10.2.1.0/24 to the LDP peer with the LSR ID 4.4.4.9. Does not advertise label bindings of other subnets to any peers. syst em- vi ew

Parameters

verbose: Displays detailed information.

|: Filters command output by specifying a regular expression. For more information about regularexpressions, see Fundamentals Configuration Guide.

begin: Displays the first line that matches the specified regular expression and all lines that follow.

exclude: Displays all lines that do not match the specified regular expression.

include: Displays all lines that match the specified regular expression.

regular-expression: Specifies a regular expression, a case-sensitive string of 1 to 256 characters.

Table 1Command outputField Description

Label Label used as the index of the fast forwarding entry.

Input_If Incoming interface.

Output_If Outgoing interface.

Len Length of the pre-header, in bytes.

FlgFlag for indicating the packet type. It can be IP, MPLS,or L2VPN.

Used Number of times the entry has been used.

Fast-Forwarding Cache PreIIpHead Content of the pre-header when the Flg field is IP.

Fast-Forwarding Cache PreMPLSHead Content of the pre-header when the Flg field is MPLS..

NOTE:

A pre-header is the content prefixed to a packet according to the matched entry in the fast forwarding cache. It

varies depending on the type of the outgoing packet:

For an IP packet, the pre-header is a link layer header. For an MPLS packet, the pre-header consists of a link layer header and a label stack. An L2VPN packet is directly forwarded out of the outgoing interface. No pre-header is prefixed to the packet.
