I know this is also beet to death but please let me konw if all the statement
under is correct :
^ $ are used to match the begining and end of expression
* + ? are used to repeat the pattrens
ba?b = bab or bb
^$ = local orignated route
.* = all route
^300$ = orignating from 300
^300_ = 300 routes and forward AS routes eg: 300,400,500
_300$ = 300 routes and backward AS routes eg: 100,200,300
_300_ = 300 routes and all routes it passes eq: 100,200,300,400,500 (if
all AS passes through it.
^300 200$ = routes from AS 300 and 200 or 200 and 300
^300[1-9]$ = routes that looks like 3001,3002,3003... till 3009
^300?1$ = routes that looks like 301 or 3001
Please correct me if i am wrong...
