Dear all

We have a Routee Cisco CISCO7609-S (M8500), running Peering BGP with several partner. I am setting new Peering BGP which its AS is 32 bytes (AS263182). Our Cisco 7609-S has IOS 12.2(33r)SRD5. I found out URL that shows how to conver AS from ASPLAIN to ASDOT notation, but couldnt setup in DOT notation, becuase seems to be that IOS doesnt have it by default.

(config-router)#bgp a?
always-compare-med  

7206VXR-HE-CCS(config-router)#neighbor 1.1.1.1 remote-as ?
  <1-65535>  AS of remote neighbor

7206VXR-HE-CCS(config-router)#neighbor 1.1.1.1 remote-as 1.1
                                                          ^

Could you please help me with this matter, DOT Notation is no workiing on our Router, so want to know if need to update IOS so far.

Your prompt reply is greatly appreciated
