RE: Grammar for IPv6 address

[Jeganatan, Srividhya]

Not really.My intent is to define policy rules that filter routes based on
an ipv6 address.
As far as I know, I need bison to define these rules.
With the token defined as one string of 4 hex digits, now I need to define a
rule that takes different combinations of 4 digit strings to form an ipv6
address.

For example, for an ipv4 address, a rule can be defined as:
ipv4address: <number> '.' <number> '.' <number> '.' <number>
                |
                <number> '.' <number> '.' <number>
                |
                <number> '.' <number>
                |
                <number>

this will then be used for the ipv4prefix along with a '/' and a prefixlen.

I am trying to define similar rules to parse an ipv6prefix (address and
prefixlen)

Thanks
SV

Your question is probably more likely to get an answer on the flex list, as
it seems that everything that you want to do doesn't require bison at all.
