AS23456 with netflow v9

Hello,

 

I installed Netflow v9 on an asr1001-x to collect BGP traffic information. But I notice in the monitoring tool that I have as23456 which appears with other ASN 2-byte. After some research, default Netflow exports only 2-byte ASNs in the template

(Table 6)

"SRC_AS 16 N (default is 2) Source BGP autonomous system number where N could be 2 or 4"

"DST_AS 17 N (default is 2) Destination BGP autonomous system number where N could be 2 or 4"

 

How can we change this data on the router ?

 

Thank you

 

Matthieu
