! flow_to_rd_map: Flow to BGP/MPLS VPN RD map
!
! File syntax is key-based. Read full syntax rules in 'pretag.map.example' in
! this same directory.
!
! nfacctd, sfacctd: valid keys: id, ip, in, out, bgp_nexthop, mpls_label_bottom.
!
! list of currently supported keys follow:
!
! 'id' SET: BGP-signalled MPLS L2/L3 VPN Route Distinguisher
! (RD) value. Encoding types #0, #1 and #2 are supported
! as per rfc4364 in asplain notation as per rfc5396.
! 'ip' MATCH: in nfacctd this is compared against the source
! IP address of the device originating NetFlow packets;
! in sfacctd this is compared against the AgentId field
! of received sFlow samples. Expected argument are an IP
! address or prefix (ie. XXX.XXX.XXX.XXX/NN). 0.0.0.0/0
! would match all IPv4 addresses; ::/0 would match all
! IPv6 addresses.
! 'in' MATCH: Input interface.
! 'out' MATCH: Output interface.
! 'bgp_nexthop' MATCH: IPv4/IPv6 address of the next-hop BGP router. In
! MPLS-enabled networks this can be also matched against
! top label address where available (ie. egress NetFlow
! v9/IPFIX exports).
! 'mpls_vpn_id' MATCH: MPLS VPN ID. A positive 32-bit unsigned integer
! is expected as value. In NetFlow/IPFIX this is compared
! against field types #234 and #235.
! 'mpls_label_bottom' MATCH: MPLS bottom label value.
!
! Examples:
!
! Maps input interface 100 of router 192.168.1.1 to RD 0:65512:1 - ie.
! a BGP/MPLS VPN Route Distinguisher encoded as type #0 according to
! to rfc4364: <2-bytes ASN>:<value> . Type #2 is equivalent to type #0
! except it supports 4-bytes ASN encoding.
!
id=0:65512:1 ip=192.168.1.1 in=100
!
! Maps the router 192.168.1.1, that is, all interfaces belonging to such
! router to RD 0:65512:1
!
id=0:65512:1 ip=192.168.1.1
!
! Maps input interface 100 of router 192.168.1.1 to RD 1:192.168.1.1:1
! ie. a BGP/MPLS VPN Route Distinguisher encoded as type #1 according
! to rfc4364: <IPv4 Address>:<value>
!
id=1:192.168.1.1:1 ip=192.168.1.1 in=100
!
! Maps input interface 100 of router 192.168.1.1 to RD 2:4200000000:1
! ie. a BGP/MPLS VPN Route Distinguisher encoded as type #2 according
! to rfc4364: <IPv4 Address>:<value>
!
id=2:4200000000:1 ip=192.168.1.1 in=100
