# mpls rsvp egress-label

#### Syntax

mpls { rsvp | traffic-eng } egress-label { non-null | explicit-null }

no mpls { rsvp | traffic-eng } egress-label

#### Release Information

Command introduced in JUNOSe Release 7.3.0.

#### Description

Specifies that the egress router advertises the explicit null label or a non-null (real) label by means of RSVP-TE. This advertisement ensures that packets received from upstream include a label and that the egress router performs ultimate hop popping. The no version restores the default condition, where the egress router advertises the implicit null label for all tunnels (except those requiring PHB) that terminate on the router.

#### Options

- rsvp—Specifies JUNOSe implementation
- traffic-eng—Specifies keyword for compatibility with non–E-series implementations
- non-null—Advertises a real label, signaling that the egress router pops the last label and performs the IP lookup; this behavior was the default before this release
- explicit-null—Advertises the explicit null label, signaling that the egress router pops the last label and performs the IP lookup

#### Mode
