Failed configuration commit on Cisco ASR 9001.

[sacapano]

When we attempt to configure new ipv4 unicast BGP neighbors, the box informs us that it can't commit the configuration. When we issue the "show configuration failed" command, we get the following error message...'BGP' detected the 'warning' condition 'Neighbor/group is not activated for this address family'(please see attachments for config we are attempting tp push and the error messages)

  address-family ipv4 unicast

   route-policy cEDGE_SERVICE_IN in

!!% 'BGP' detected the 'warning' condition 'Neighbor/group is not activated for this address family'

   route-policy cEDGE_SERVICE_OUT out

!!% 'BGP' detected the 'warning' condition 'Neighbor/group is not activated for this address family'

how is your BGP configuration looks like :

or check below syntax :

Example 1-3 IOS XR BGP Configuration

IOS XR
router bgp 65100
 bgp router-id 192.168.1.1
 address-family ipv4 unicast
 !
 neighbor 10.1.12.2
  remote-as 65100
  address-family ipv4 unicast

Hello @sacapano ,

IOS XR configuration is stricly hierarchical as shown by BB you need to configure address-famiily ipv4 unicast under each neighbor in order to activate the neighbor for the AF.

Hope to help

You need to configure address-famiily ipv4 unicast under each neighbor in order to activate the neighbor for the Address-Family as per @Giuseppe Larosa @balaji.bandi

Thanks for all your help, they been configure the address -family ipv4 unicast under each neighbor but still the issue has persist when trying to commit , they tried to do it in a lab but it works  , they suspect it has a problem with older code or policy, I contacted the tac to investigate further.

when you configuring, capture the logs from the begin of the config and until error - not that bit your got error for us to understand.

if you can not replicate it, post the BGP config for us to review. (what IOS XE code running, show version help you)
