Release Information

Statement introduced before JUNOS Release 7.4.

Description

Enable link protection on the specified interface. Using link protection, you can configure a network to reroute traffic quickly around broken links. To fully enable link protection, you also need to configure the link-protection statement at the [edit protocols mpls label-switched-path lsp-name] hierarchy level. You can configure single or multiple bypasses for protected interface.

Default

Link protection is disabled.

Options

no-node-protection—Disables node-link protection on the RSVP interface. Link protection remains active. When this option is configured, the router can only initiate a next-hop bypass, not a next-next-hop bypass.
The remaining statements are explained separately.

Usage Guidelines

See Configuring Node Protection or Link Protection.

Required Privilege Level

routing—To view this statement in the configuration.

routing-control—To add this statement to the configuration.
