getting "Policy commands not allowed without an address family" BGP

[Sanjeloff]

Hi,

I am on my lab trying to do a BGP peer group prefix-filter, my goal is to deny private IPs using prefix-list from the ISP-PG peer group.

everything is configured on prefix-list and neighbor is established

When I enter

neighbor ISP-PG prefix-list FILTER-IP in

I am getting a notification

Policy commands not allowed without an address family

I did try to add it on

address-family ipv4 unicast

but still getting same notification. Then I notice doing it on specific neighbor I also get the same notification. I am not sure what I am missing. any help much appreciated, thank you.

no bgp default ipv4-unicast 

<<- I do lab and after I remove this line the prefix-list accept, so please remove it and try again

I did try to input

no bgp default ipv4-unicast

but I still get the same notification with peer group and specific neighbor. Appreciate the help

OK, 

no router bgp xx
then config 
router bgp xx <<- but this time with no bgp default ipv4-unicast

I did try to reconfigure but it is still not working, It maybe an issue with the router image I am using, I did try it on another image and it works. Thank you for the help.
