if-match protocol (Flow-Route view)

Format

if-match protocol { greater-than | less-than | equal } { icmp | igmp | ipip | tcp | egp | udp | ipv6 | rsvp | gre | esp | ospf | pim | protocol | icmpv6 }

if-match protocol greater-than { icmp | igmp | ipip | tcp | egp | udp | ipv6 | rsvp | gre | esp | ospf | pim | protocol | icmpv6 } less-than { icmp | igmp | ipip | tcp | egp | udp | ipv6 | rsvp | gre | esp | ospf | pim | icmpv6 | upper-protocol-value }

undo if-match protocol

undo if-match protocol { greater-than | less-than | equal } { icmp | igmp | ipip | tcp | egp | udp | ipv6 | rsvp | gre | esp | ospf | pim | protocol | icmpv6 }

undo if-match protocol greater-than { icmp | igmp | ipip | tcp | egp | udp | ipv6 | rsvp | gre | esp | ospf | pim | protocol | icmpv6 } less-than { icmp | igmp | ipip | tcp | egp | udp | ipv6 | rsvp | gre | esp | ospf | pim | icmpv6 | upper-protocol-value }

Parameters

Parameter	Description	Value
greater-than	Indicates that the IP protocol ID is greater than the specified one.	-
less-than	Indicates that the IP protocol ID is smaller than the specified one.	-
equal	Indicates that the IP protocol ID is equal to the specified one.	-
protocol	Specifies a protocol type with a name or number.	The value is an integer that ranges from 0 to 255. The options are as follows: 1: ICMP 2: IGMP 4: IPIP 6: TCP 8: EGP 17: UDP 41: IPv6 46: RSVP 47: GRE 50: ESP 58: ICMPv6 89: OSPF 103: PIM
upper-protocol-value	Specifies the upper limit of an IP protocol ID range.	The value is an integer that ranges from 0 to 255. The options are as follows: 1: ICMP 2: IGMP 4: IPIP 6: TCP 8: EGP 17: UDP 41: IPv6 46: RSVP 47: GRE 50: ESP 58: ICMPv6 89: OSPF 103: PIM

Usage Guidelines

Usage Scenario

The if-match protocol command is used to configure a filtering rule based on the IP protocol name or number for a BGP (IPv6) Flow Specification route or BGP (IPv6) VPN Flow Specification route. Traffic matching the filtering rule will be controlled with the action specified by the apply clause.

Prerequisites

A static BGP (IPv6) Flow Specification route or BGP (IPv6) VPN Flow Specification route has been created using the flow-route command in the system view.

Precautions

A maximum of five filtering rules based on the IP protocol type can be configured for a BGP Flow Specification route.

Example

# Configure a filtering rule that is based on a protocol ID range for the static BGP Flow Specification route Rule1.

# Configure a filtering rule that is based on the TCP protocol for the static BGP Flow Specification route Rule 1.
