Apologies, as my REGEX-fu is weak today.

I'm attempting to filter off certain interface from showing up via an SNMP
walk... i.e. interfaces that are internally generated which really serve no
purpose outside the JunOS box itself: (lsi.*, lo0.16384, etc)

I want to match any ge-x/x/x interface that has .32767 (which is the
RE-to-PIC communications interface that is created on many PICs/MPCs/DPCs -
which only serves to confuse my Ops guys as well as clutter up any
MRTG-style graphs.)

This works (as an example) to suppress:

snmp
 {
 filter-interfaces {
    interfaces {
        lsi.*;
        cbp*;
        demux*;
        pimd*;
        pime*;
        pip*;
        tap*;
        lo0.16384;
    }
    all-internal-interfaces;
}


But this does not (i.e. I cant find a good example of how to match 'any
interface' as long as it's unit 32767):

snmp
 {
 filter-interfaces {
    interfaces {
        *.32767;
        *32767;
        ge*.32767
        ge*32767;
    }
    all-internal-interfaces;
}

Pointers/Suggestions/Example Stanza Appreciated. I will send you a Blueberry
Pie.

P.S. Dear JNPR - any reason we aren't including xxx.32767, lo0.16384, etc..
as part of the default "all-internal-interfaces" directive? Seems like a
natural to me.
