Potential bgpd.conf parsing bug?

[Jordan Geoghegan]

Hello,

I was playing around with my bgpd.conf and I noticed some interesting 
behaviour with macros.

A quick example:

# This parses fine:
IP1="192.0.2.1"
MYIP=$IP1

# This throws a syntax error:
ASN1="65001"
MYASN=$ASN1

# This also parses fine:
ASN1="65001a"
MYASN=$ASN1

In short, it appears that having a numerical value for macro2=$macro1 
breaks something in the config parser, or at the very least the 
behaviour is undocumented.

Any insight or advice would be much appreciated.

Regards,

Jordan
