[ixpmanager] Lifting sanity check for first ASN check up

[Jasper Yu]

Hi,

You should use the PHP as Template Engine, and wrap the whole section in
that like
<?php if($int['autsys'] != 65000): ?>
# Peer ASN == route's first ASN?
if (bgp_path.first != <?= $int['autsys'] ?> ) then {
    bgp_large_community.add( IXP_LC_FILTERED_FIRST_AS_NOT_PEER_AS );
    accept;
}
<?php endif; ?>

 Thanks
ᐧ
