[j-nsp] Back-reference in JunOS regular expressions

[Michael Hallgren]

Hi,

Is back-reference, like (.)( \1)*$, provided by the JunOS AS-path
matching engine? (This should match, for instance, ^6453$, ^6453_6453$,
^6453_6453_6453$, and so on...)

I can't find a firm statement in the JunOS documentation, and some
tests makes me believe it's not implemented. Or am I mistaken with
the syntax? (I can use back-reference in 'replace', etc, etc...)

Cheers,
mh
