! BGP source MED (Multi Exit Discriminator) 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, bgp_nexthop, src_mac.
!
! list of currently supported keys follow:
!
! 'id' ID value to assign to a matching packet or flow. Other
! than hard-coded MED values this field accepts also the
! 'bgp' keyword which triggers a BGP lookup and returns
! its result: useful to handle exceptions.
! 'ip' In nfacctd it's compared against the source IP address
! of the device which is originating NetFlow packets; in
! sfacctd this is compared against the AgentId field of
! received sFlow samples.
! 'in' Input interface.
! 'bgp_nexthop' BGP next-hop of the flow source IP address (RPF-like).
! This value is compared against the corresponding BGP
! RIB of the exporting device.
! 'peer_dst_as' First AS hop within the AS-PATH of the source IP address
! (RPF-like). This value is compared against the BGP RIB
! of the exporting device (see 'bgp_daemon' configuration
! directive).
! 'src_mac' Source MAC address of the flow. Requires NetFlow v9,
! IPFIX or sFlow.
!
! A few examples follow.
!
! Customer connected to router with IP address 192.168.2.1, SNMP ifIndex 7
