“.” – match any character
“|” – concatenates constructs. matches one of the characters or character patterns on either side of the vertical bar.
“[]” – matches the character following the backslash
“[0-9]” – match any single digit
“[a-z]” – match any lower case
“[A-Z] – match any upper case
“_” – replaces a long regular expression list by matching a comma (,), left brace ({), right brace (}), the beginning of the input string, the end of the input string, a space or the end of an AS Path.
“^” – match the beginning of a string.
“$” – match the end of a string
“\\” – matches the character following the backslash and also escapes special characters. <\/p>\n
“?” – means 0 or 1 times. matches zero or one occurrence of the pattern
