BGP Problem "forming a neighborhood"

yrwins

need some help with BGP...

im using OSPF and i can ping from 5.5.5.5 with source of 1.1.1.1 the loopback0 R1 to R5"

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
