Routing

Hi All,

I am not very experinced in Junos system and would require some help.

I am trying to export all the routes learned from eBGP into the vrf export policy. I am learning around 2800 from eBGP but only exporting 600 into the vrf export policy.

admin@srbah2-re0> show route receive-protocol bgp 194.6.15.195 table gp-vrf.inet.0 | count
Count: 2831 lines

{master}
admin@srbah2-re0> show route advertising-protocol bgp 192.168.33.44 table gp-vrf.inet.0 | count
Count: 611 lines

below the export policy used
admin@srbah2-re0> show configuration policy-options policy-statement gp_export
term a {
    from protocol [ bgp static ];
    then {
        community add gp-vrf;
        accept;
    }
}

and also attached the configuration for the gp-vrf routing instance

Any idea why only some routes are exported and not all routes?

Thanks in advance.

Regards,
Mubarak

After checking the configuration I think I know what is the problem here.

I just want to confirm.

in the export policy is the router only export the ACTIVE  BGP routes? 

Because most of the routes learned from BGP are not active ( used as a backup routes ) is this the reason why they are not advertised into the export policy?

Yes. BGP always export only active routes.

If you really want to advertise inactive routes, Juniper created a knob for this situation, called advertise-inactive. When applied to an EBGP peering session, this knob results in the advertisement of the best BGP route that happens to be inactive because of IGP preference....
