You can collect those counters via SNMP (probably) and via the JunOS
built-in accounting functions (sure):

dr at A1# set accounting-options interface-profile foo fields ?
Possible completions:
[...]
  rpf-check-bytes      Bytes failing IPv4 reverse-path-forwarding check
  rpf-check-packets    Packets failing IPv4 reverse-path-forwarding check
  rpf-check6-bytes     Bytes failing IPv6 reverse-path-forwarding check
  rpf-check6-packets   Packets failing IPv6 reverse-path-forwarding check


Best regards,
