Peer A starts the initial connection to Cogent.  Peer B is for advertising the routes.

A.A.A.A = Cogent Peer A IP address
B.B.B.B = Cogent Peer B IP address
X.X.X.X = Your interface IP (assigned by Cogent)

protocols {         
    bgp {           
            group Cogent-Peer-A {
            type external;
            neighbor A.A.A.A {
                import cogent-peer-policy; ### Set this policy to allow all from Cogent Peer A
                authentication-key "xxx"; ### Set your bgp password that was assigned to you from Cogent
                export my-bgp-network; ### Policy that advertises your routes to Cogent
                peer-as 174;
            }       
        }           
        group Cogent-Peer-B {
            type external;
            local-address X.X.X.X;
            neighbor B.B.B.B {
                multihop {
                    ttl 6;
                }   
                import cogent-policy; ### Policy to allow all routes from Cogent or filter them as needed
                authentication-key "xxx"; ### Set your bgp password that was assigned to you from Cogent
                peer-as 174;
            }       
        }  

You will need to set your IP assigned by Cogent on the loop back interface    

 interfaces {
        lo0 {
        description Loopback;
        unit 0 {
            family inet {
                address 127.0.0.1/32;
                address X.X.X.X/32;
            }
        }
    }

Don't forget to setup your policies.
