Multi value rangeMatch on the total IP packet length (excluding
Layer 2, but including IP header). Values are
encoded using 1- or 2-byte quantities.
Encoding: <type (1 octet), [op, value]+>
Syntax:
matchpacket length {packet-length-value
|min-value -max-value}
IPv4 Packet lengthType 10
Multi value rangeDefines a list of {operation, value} pairs used
to match the 6-bit DSCP field. Values are
encoded using a single byte, where the two
most significant bits are zero and the six least
significant bits contain the DSCP value.
Encoding: <type (1 octet), [op, value]+>
Syntax:
match dscp {dscp-value |min-value
-max-value}
IPv4 DSCPType 11
Bit maskIdentifies a fragment-type as the match
criterion for a class map.
Encoding: <type (1 octet), [op, bitmask]+>
Syntax:
match fragment type [is-fragment]

In a given flowspec rule, multiple action combinations can be specified without restrictions.
Redirect IP Nexthop is only supported in default VRF cases.Note
Traffic Filtering Actions, on page 209 provides information on the actions that can be associated with a flow.
How to Configure BGP Flowspec, on page 212 explains the procedure to configure BGP flowpsec with the
required tuple definitions and action sequences.
Traffic Filtering Actions
The default action for a traffic filtering flow specification is to accept IP traffic that matches that particular
rule. The following extended community values can be used to specify particular actions:
