configure mpls rsvp-te lsp transport

configure mpls rsvp-te lsp lsp_name transport [ip-traffic [allow | deny] | vpn-traffic [allow {all | assigned-only} | deny]]

Description

Configures the type of traffic that may be transported across a named LSP.

Syntax Description

lsp_name Specifies the RSVP-TE LSP.
ip-traffic Controls the forwarding of routed IP traffic across the specified LSP.
vpn-traffic Controls the forwarding of VPN traffic over the LSP.
allow Allows transport of the specified traffic across the LSP.
deny Denies transport of the specified traffic across the LSP.
allow Allows all VPLS VPN traffic to be transported across the LSP.
all Allows the transmission of all VPN traffic over the LSP.
assigned-only Limits the transport of VPN traffic to VPLS instances that are explicitly configured to use the specified LSP name.

Default

The default behavior is to allow RSVP-TE LSPs to transport all types of traffic without restriction.

Usage Guidelines

This command configures the type of traffic that may be transported across a named LSP. By default, both IP traffic and VPN traffic are set to allow transport for a newly created LSP. The ip-traffic keyword is used to allow or deny forwarding of routed IP traffic across the specified LSP. If allowed, the LSP label information is inserted into the routing table and the switch forwards traffic over the LSP that matches the IP route entry to which this LSP is associated. If denied, the LSP label information is removed from the routing table and the switch does not use the LSP to transport IP traffic. The vpn-traffic keyword controls the transmission of VPN traffic over the LSP. When denied, the LSP is not used as a transport for PWs or other VPN related traffic. These transport configuration options are independent. For example, if vpn-traffic is set to allow and ip-traffic is set to deny, then no routed IP traffic is transported across the LSP, but the LSP may still be used to transport VPN traffic.

The optional assigned-only keyword limits the transport of VPN traffic to only those VPLS instances that are explicitly configured to use the specified LSP name.

Example

The following command prevents the switch from using LSP aus to forward IP traffic:

configure mpls rsvp-te lsp aus transport ip-traffic deny
