Hello All,
I am following Jeremy Cioras lab on BGP for the CCNP Route. BGP remians IDLE.
What am I missing?
I have two new Just Started 7200 routers, connected to se1/0 on both with a serial connection.
R1: 10.1.1.1 255.255.0.0 AS 6500
R2: 10.2.1.1 255.255.0.0 AS 5500
R1: Shows neighbor 10.2.1.1 AS 5500
R2: Shows neighbor 10.1.1.1 AS 6500
I added a static route on both sides and was able to ping (for troubleshooting)
What Am I not doing?
Any help is appreciated.

the above IP addresses are not on the same subnet. So what are they ie. are they loopback addresses ?
What IPs have you used on the serial interfaces ?
Assuming the above IPs are assigned to loopbacks you should add this to your BGP config on both routers -
router bgp
neighbor x.x.x.x ebgp-multihop 2
neighbor x.x.x.x. update-source loopback
if they are not loopbacks can you clarify what the static routes you added were for ?

Does it just stay in idle or does it jump between idle and connect? Seems your TCP is not able to connect. Post configuration, output of ping and try telnet x.x.x.x 189 where x.x.x.x is IP of other host.

OK. I figured it out.
I started the lab with the two routers on different subnets, The lab starts off with two router/two ASN/1 Subnet.
Thanks
