    on your 7th line you put:
    neighbor 5.5.5.5 remote-as 655536

    The last line shows that the AS as 655536. (You entered a extra 5)

    I'm currently working on my CCNA and have little experience but at the very least I did notice that you had a a extra digit. Actually on that note, AS can be used 0-65535 - which means in total there are 65536 AS numbers but 65536 would not be a valid one.

    I have gotten eBGP to work but not with using a loopback address.

    R1- AS 100 - 192.168.1.1/24 -- (R1 also has a network 10.250.0.0/16 attached to it)
    R2- AS 200 - 192.168.1.2/24 -- (R2 also has a network 10.100.0.0/16 attached to it)

    on R1
    router bgp 100
    network 192.168.1.0 mask 255.255.255.0
    network 10.250.0.0 mask 255.255.0.0
    neighbor 192.168.1.2 remote-as 200

    on R2
    router bgp 200
    network 192.168.1.0 mask 255.255.255.0
    network 10.100.0.0 mask 255.255.0.0
    neighbor 192.168.1.1 remote-as 100

    Hopefully this helps...or you might be doing something that I'm not aware of/thinking of.

    Your welcome! I'm glad that you were able to get it to work. Also this was a nice boost on my own confidence that has been bruised from months of studying. I'm finally starting to see some fruit :)
