authentication-key (Protocols RSVP)

Syntax

Hierarchy Level

Description

Authentication key (password). Neighboring routers use the password to verify the authenticity of packets sent from this interface or peer interface. To authenticate node hellos or remote messages between the Point of Local Repair (PLR) to the Merge Point (MP), enable authentication-key at the [edit protocols rsvp] hierarchy level.

It is recommended to use the authentication-key configuration at the [edit protocols rsvp] hierarchy level for the RSVP node-neighbor. Because non-RSVP interfaces do not have RSVP authentication key, the authentication-key configuration allows the packets to arrive at any interface regardless of RSVP interfaces configuration being enabled or not.

RSVP uses HMAC-MD5 authentication, which is defined in RFC 2104, HMAC: Keyed-Hashing for Message Authentication.

All routers that are connected to the same IP subnet must use the same authentication scheme and password.

Options
