The OID in snmp.c doesn't match the RFC, it should be like this:
#define OIDIDX_bgp4 7
static struct snmp_oid bgpd4oid = {
{ 1, 3, 6, 1, 2, 1, 15 },
7
};
With that fixed, I can fetch single values, but walking fails:
$ snmpget -On -m+BGP4-MIB -v2c -c public 127.0.0.1 BGP4-MIB::bgpLocalAs
.1.3.6.1.2.1.15.2 = INTEGER: 61006
$ snmpwalk -On -m+BGP4-MIB -v2c -c public 127.0.0.1 .1.3.6.1.2.1.15
.1.3.6.1.2.1.15 = No Such Instance currently exists at this OID
$ snmpwalk -On -m+BGP4-MIB -v2c -c public 127.0.0.1 BGP4-MIB::bgpVersion
.1.3.6.1.2.1.15.1 = Hex-STRING: 08
Error: OID not increasing: .1.3.6.1.2.1.15.1
