Configuring Link Protection or Node-Link Protection on the LSP
You enable the level of LSP protection you want
on the ingress router. Link protection redirects LSP traffic to a
bypass LSP that can traverse the same router that contains the affected
link, whereas node-link protection sends LSP traffic to a bypass LSP
that circumvents the affected router. To enable link protection for
an LSP or point-to-multipoint LSP, include the link-protection statement at the [edit protocols mpls label-switched-path lsp-name ] hierarchy level. To enable node-link
protection for an LSP, include the node-link-protection statement at the [edit protocols mpls label-switched-path lsp-name] hierarchy level.
[edit]
protocols {
mpls {
label-switched-path lsp-name {
( link-protection | node-link-protection );
}
}
}
After link protection or node-link protection is
established, the LSP marks the desired link protection bit in the
RSVP Session Attribute (SA) object. To disable link protection or
node-link protection for an LSP, delete the link-protection or node-link-protection statements at the [edit
protocols mpls label-switched-path lsp-name] hierarchy level. For more information
about point-to-multipoint LSPs, see the Junos MPLS Applications
Configuration Guide.
