Re: look for BGP routes containing local AS#

Can you clarify what do you mean by 'local AS' ? regards Carlos On 1/27/15 11:48 AM, Song Li wrote:

Hi everyone,

Recently I studied the BGP AS path looping problem, and found that in most cases, the received BGP routes containing local AS# are suspicious. However, we checked our BGP routing table (AS23910,CERNET2) on juniper router(show route hidden terse aspath-regex .*23910.* ), and have not found such routes in Adj-RIB-In.

We believe that the received BGP routes containing local AS# are related to BGP security problem. Hence, we want to look for some real cases in the wild. Could anybody give us some examples of such routes?

Thanks!

Best Regards!
