Syntax

Hierarchy Level

Description

Export the BGP community and AS path information in the data record using IPFIX, per RFC 8549. The IPFIX collector should be RFC 6313 compliant to decode data records carrying fields with the basicList format. Any new or changed configuration of this statement is effective immediately and the exported packets contain the new information.

count defines the size of the list that will be exported for that Information Element in the data record. If the total number of items exceeds the configured list size, the exported list contains the first and subsequent items up to and including the configured list size. For example, if the AS path list for the source prefix contains 8 AS numbers, but count is set to 4, only the first four AS numbers are exported in the data record.

Each Information Element is independent of the others and can be exported separately in the collector record.

Default

When this statement is not configured, the routing protocol process (rpd) only sends the peer AS number, origin AS number, and the BGP next-hop information. When this statement is configured with at least one Information Element, rpd sends all of the community and AS-path-related information. You do not have to configure all of the Information Elements.

Options

source-prefix-as-path count

Export the source prefix AS path (Information Element 16, per RFC 6313).

  • Default: 8
destination-prefix-as-path count

Export the destination prefix AS path (Information Element 17, per RFC 6313).

  • Default: 8
bgp-source-standard-community count

Export the standard BGP community list for the source prefix, corresponding to a specific flow's source IP address (Information Element 484, per Appendix A of RFC 8549).

  • Default: 8
bgp-destination-standard-community count

Export the standard BGP community list for the destination prefix, corresponding to a specific flow's destination IP address (Information Element 485, per Appendix A of RFC 8549).

  • Default: 8
bgp-source-extended-community count

Export the extended BGP community list corresponding to a specific flow's source IP address (Information Element 487, per Appendix A of RFC 8549).

  • Default: 8
bgp-destination-extended-community count

Export the extended BGP community list corresponding to a specific flow's destination IP address (Information Element 488, per Appendix A of RFC 8549).

  • Default: 8
bgp-destination-large-community count

Export the large BGP community list corresponding to a specific flow's destination IP address (Information Element 491, per Appendix A of RFC 8549).

  • Default: 8
