Re: Conditional Advertise

Thanks for trying that, as I said I cannot get this to work :).

Please experts out there if you can provide a solution to meet this
requirement below.

Bgp should check its bgp routing table for two routes eq (10.1.1.0/24 and
20.2.2.2/32) and *only if both routes are present*, it should originate a
route advertisement of 192.168.10.0/24.

Regards,
Sagar
