I'm guessing your software is too old. Are you able to upgrade to a 15.x release?
You could look at using the magic BGP ASN 23456, which is used for transitioning systems from 2 to 4 byte ASNs. Check out this document and search for 23456. I'm not sure how much it will help in this particular case though. Its a bit tricky.

I just had a read of this further, and it says after configuring "bgp asnotation dot" you must perform a hard reset of the BGP process before further configuration. Perhaps try a "clear ip bgp *" then see if you can configure the rd.

Just read something interesting. It looks like it only affects the output of "show" commands, as opposed to the input.
04-14-2016 08:49 PM
From asplain is default which shows as normal formate.
after enter the as-notation AS is converted into Dot form.
i am looking to design mpls and bgl with 4 byte AS number.
what i have read so far is community string with 4 byte is not possible??
looking some deisgn documents for better understanding.

i did this before,
here is the log for you reference , i did again.
Router#clear ip bg
Router#clear ip bgp *

Router#config t
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#vrf de

And if you enter it in asplain notation, and then do a "show running" is it displaying it in dotted notation?
04-14-2016 09:19 PM
no it will be back to plaintext format..

Hi,
I think it is a DOC bug. Can you try some 15.4 release?. I think it might not be available for 7200. So try in a different router with 15.4.
I remember using 4byte ASN based RD but dont think I have seen it in 15.2 or 15.3.

Tried with 15.4 in 7200 same story.
We need to make it on 7200 as it act as edge for the mpls core.
Also assigning the community using as:value is not possible with 4byte AS.
