configure mpls static lsp

configure mpls static lsp lsp_name [{egress [egress_label | implicit-null] egress-vlan evlan_name next-hop ipaddress} {ingress ingress_label {ingress-vlan ivlan_name}}]

Description

Configures the ingress and egress segments of a static LSP.

Syntax Description

lsp_name Identifies the static LSP to be configured.
egress_label

Specifies the egress label for the LSP. The supported range is x7FC00 to x803FF.

The egress label should match the corresponding ingress label of the next hop. There is no egress label at the egress LSR of a static LSP.

egress implicit-null If PHP is supported, an LSR can be configured to use the implicit-null label for LSPs that terminate at the next-hop LER.
evlan_name Specifies the egress VLAN (Virtual LAN) for the LSP.
ipaddress Specifies the IP address for the next-hop router along the static LSP.
ingress_label

Identifies the ingress label for this LSP. The supported range is x7FC00 to x7FFFF at transit LSRs and 0x80000 to 0x803FF at destination LSRs.

The ingress label should match the corresponding egress label of the previous hop. There is no ingress label at the ingress LSR of a static LSP.

ivlan_name When an ingress label is specified, this argument optionally specifies the ingress VLAN for the LSP.

Default

N/A.

Usage Guidelines

The ingress and egress segments can be configured any time before enabling the LSP. At the ingress LER, only the egress segment is configured and at the egress LER, only the ingress segment is configured. For LSPs that transit an LSR, it is mandatory to configure both ingress and egress segments. On any given LSR, the ingress label, if present, must match the egress label on the upstream LSR and the egress label must match the ingress label of the downstream LSR. Once configured, any change to the ingress or egress segments requires administratively disabling the LSP first. If the next-hop IP address is not within the subnet as defined by the interface VLAN name, the configuration is rejected.

Example

The following command configures a static LSP on an ingress LSR:

configure mpls static lsp lsp1 egress 0x7fc01 egress-vlan v50 next-hop 50.0.0.2

The following command configures a static LSP on a transit LSR:

configure mpls static lsp lsp1 egress 0x80001 egress-vlan v100 next-hop 100.0.0.2 ingress 0X7FC01 ingress-vlan v50

The following command configures a static LSP on an egress LSR:

configure mpls static lsp lsp1 ingress 0x80001  ingress-vlan v100
