static-cr-lsp transit

Function

The static-cr-lsp transit command configures a static CR-LSP on a transit LSR.

The undo static-cr-lsp transit command deletes a static CR-LSP from the transit LSR.

By default, no static CR-LSPs are configured.

Format

static-cr-lsp transit lsp-name [ incoming-interface { incoming-interfacename | { incoming-interfacetype incoming-interfacenum } } ] in-label in-label { outgoing-interface { outgoing-interfacename | { outgoing-interfacetype outgoing-interfacenum } } | nexthop next-hop-address } ^* out-label out-label [ ingress-lsrid ingress-lsrid egress-lsrid egress-lsrid tunnel-id tunnel-id ] [ [ bandwidth { [ ct0 ] bandwidth } ] | [ pir pir ] ] ^*

Parameters

Parameter	Description	Value
lsp-name	Specifies the name of an LSP.	The value is a string of 1 to 19 case-sensitive characters. It cannot contain spaces. However, the character string can contain spaces if it is enclosed with double quotation marks (").
incoming-interface incoming-interfacename	Specifies the name of an inbound interface.	-
incoming-interfacetype	Specifies the type of an inbound interface.	-
incoming-interfacenum	Specifies the number of an inbound interface.	-
in-label in-label	Indicates an incoming label.	The value is an integer ranging from 16 to 32783.
outgoing-interface outgoing-interfacename	Specifies the name of an outbound interface.	-
outgoing-interfacetype	Specifies the type of an outbound interface.	-
outgoing-interfacenum	Specifies the number of an outbound interface.	-
nexthop next-hop-address	Specifies the next hop address.	This value is in dotted decimal notation.
out-label out-label	Specifies the outgoing label.	The value is an integer ranging from 16 to 1048575.
ingress-lsrid ingress-lsrid	Specifies the ingress LSR ID.	This value is in dotted decimal notation.
egress-lsrid egress-lsrid	Specifies the LSR ID of the peer node (egress).	The value is in dotted decimal notation.
tunnel-id tunnel-id	Specifies the tunnel ID.	The value is an integer ranging from 1 to 65535.
bandwidth	Configures bandwidth.	-
ct0 bandwidth	Specifies the CT0 reserved bandwidth.	The value is an integer ranging from 0-4000000000, in kbit/s.
pir pir	Specifies peak information rate (PIR) of reservable bandwidth. This parameter is mandatory when ct0 bandwidth is not set to 0.	The value is an integer ranging from 0-4000000000, in kbit/s. The value cannot be smaller than the value of bandwidth.

Usage Guidelines

Usage Scenario

On devices with low routing and processing performance, a static CR-LSP can be established to implement MPLS TE functions. Labels for a static CR-LSP are assigned manually. Static CR-LSP configuration involves the operations on the following types of nodes:

Ingress: configured using the static-cr-lsp ingress command.
Transit node: configured using the static-cr-lsp transit command.
Egress: configured using the static-cr-lsp egress command.
To modify the inbound interface name, incoming label value, next-hop address, outbound interface name, or outgoing label value, run the static-cr-lsp transit command to set a new value. There is no need to run the undo static-cr-lsp transit command before changing a configured value.

Prerequisites

MPLS TE has been enabled globally using the mpls te command.

Example

# Configure the static CR-LSP named tunnel34, with the incoming interface of GE0/1/8, the next-hop IP address of 10.2.0.2, the incoming label of 123, the outbound interface of GE0/1/0, the outgoing label of 253, the desired CT0 bandwidth of 20 kbit/s on a transit node.
