How to avoid getting BGP routes while getting a router's routing table

Hi everyone,

I am using SNMP to get a router's routing table, but it takes a lot of
time because this router has BGP routes. Is there any way to avoid
getting its BGP entries?

This is the route entry oid that i use to get the route table
information:
.1.3.6.1.2.1.4.21.1

Thanks in advance,

Drill down more and you get the .9 which is by protocol

OID 1.3.6.1.2.1.4.21.1.9
Type INTEGER
Units
Access read-only
Status mandatory

The routing mechanism via which this route was
learned. Inclusion of values for gateway routing
protocols is not intended to imply that hosts
should support those protocols.

Possible Values :
other(1)
local(2)
netmgmt(3)
icmp(4)
egp(5)
ggp(6)
hello(7)
rip(8)
is-is(9)
es-is(10)
ciscoIgrp(11)
bbnSpfIgp(12)
ospf(13)
bgp(14)

 

I know that the OID 1.3.6.1.2.1.4.21.1.9 returns the routing protocol.
When i try to get that information, it takes a lot of time because the
table returned has 171091 entries and i only want those that the
routing protocol is ospf.
Is there any way of getting only the ospf entries in order to take less
time?

Thanks in advance,
