Hello Robin

based on my understanding of the above configuration, CER is your interface IP. Your ASN is 65103 and AT&T is 13979. The VPNID is something that relevant to AT&T and not your network. Regarding the VLAN 50, I am not sure if you have a switch in middle or is it an access port on the other side of your link. You can try creating a sub-interface with dot1q tag of 50.

inter gix/x.50

encap dot 50

ip add 192.168.xxx.3 255.255.255.252

router bgp 65103

bgp router-id x.x.x.x

no bgp default ipv4-unicast

neighbor 192.168.xxx.4 remot 13979

address-family ipv4 unicast

neighbor 192.168.xxx.4 activate

You may use other attirbutes as well as per your requirement.

I dont think there should be any different configuration that might be required.

Thanks for the config. Is the router ****bgp router-id X.X.X.X *********my router ip that host this config ?

You can have the router-id as your loopback IP or any physical interface IP.
