Description

Authentication key (password). Neighboring routers use the password to verify the authenticity of packets sent from this interface.

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

key—Authentication password. It can be 1 to 16 contiguous digits or letters. Separate decimal digits with periods. Separate hexadecimal digits with periods and precede the string with 0x. If you include spaces in the password, enclose the entire password in quotation marks (" ").
