[c-nsp] BGP conditional advertisemet - NON-EXIST route map's access-list problem

[Burak Dikici]

Hi Mateusz ,

For better understanding , i have attached the topology screenshot and the
router's configuration files. (By the way , this is a lab config.)

In the attached Router's configuration ,

access-list 65 permit 172.16.1.0 0.0.0.255

command is used and with this command bgp conditional advertisement is
working fine.

But when i use ,

access-list 65 permit any

command , the conditional advertisement doesn't work.

Regards.
