bgp: optional object {customer\_asn, extra\_prefixes, md5\_key }

customer\_asn: number ASN used on the customer end of the BGP session formatint32 minimum0 Link to this property extra\_prefixes: array of string Extra set of static prefixes to advertise to the customer’s end of the session Link to this property md5\_key: optional string MD5 key to use for session authentication. Note that *this is not a security measure*. MD5 is not a valid security mechanism, and the key is not treated as a secret value. This is *only* supported for preventing misconfiguration, not for defending against malicious attacks. The MD5 key, if set, must be of non-zero length and consist only of the following types of character: - ASCII alphanumerics: [a-zA-Z0-9] - Special characters in the set '!@#$%^&*()+[]{}<>/.,;:_-~= |\` In other words, MD5 keys may contain any printable ASCII character aside from newline (0x0A), quotation mark ("), vertical tab (0x0B), carriage return (0x0D), tab (0x09), form feed (0x0C), and the question mark (?). Requests specifying an MD5 key with one or more of these disallowed characters will be rejected. Link to this property
