configure l2vpn vpws add peer ipaddress

configure l2vpn vpws vpws_name add peer ipaddress ipaddress {static-pw transmit-label outgoing_pw_label receive-label incoming_pw_label }

Description

Configures L2VPN VPWS service over MPLS Static PW.

Syntax Description

vpws_name

Specifies the VPWS for which you are configuring a peer.

ipaddress

Specifies the peer IP address.

ipaddress

Specifies the IP address of the peer node.

static-pw transmit-label

Specifies the static pseudowire transmit label.

outgoing_pw_label

Specifies the name of the egress label.

receive-label

Specifies the static PW receive label.

incoming_pw_label

Specifies the name of the ingress label.

   

Default

N/A.

Usage Guidelines

Use this command to statically configure a new MPLS Ethernet PW for the specified VPWS. You must specify the outgoing (MPLS ingress) and incoming (MPLS egress) PW labels. Similarly, you must configure the peer with a static PW that has the reverse PW label mappings.

Locally, the incoming_pw_label must be unique and is allocated out of the static label space. The outgoing_pw_label must match the peer‘s configured incoming PW label.

Just like a signaled PW, a static PW can optionally be configured to use any type of tunnel LSP: LDP, RSVP-TE, or Static. In the case of RSVP-TE and LDP, those protocols must be configured and enabled and an LSP must be established before traffic can be transmitted over the static PW.

For Static LSPs, only the MPLS ingress LSP (or outgoing LSP) is specified. Unlike signaled PWs, there is no end-to-end PW communication that is used to verify that the PW endpoint is operational, and in the case of static LSPs, that the data path to the PW endpoint is viable. In the event of a network fault, if a secondary RSVP-TE LSP is configured or the routing topology changes such that there is an alternate LDP LSP, the static PW will automatically switch LSPs in order to maintain connectivity with the PW endpoint. Static LSPs can be protected proactively by configuring BFD to verify the static LSPs IP next hop connectivity. Optionally, the underlying LSP for the PW can be explicitly specified using a named LSP. When a named LSP is explicitly specified, only the specified named LSP is used to carry the PW. In the event that a specified named LSP is withdrawn, the VPLS/VPWS remains operationally down until the named LSP is restored.

Since VC Status signaling is not supported, the VC Status “standby” bit cannot be used to allow support for PW redundancy and H-VPLS. Consequently, only “core full-mesh” PWs are allowed to have statically configured labels.

Example

The following command configures VPWS service for VPWS1 on peer 1.1.1.202:

configure vpws vpws1 add peer 1.1.1.202
