evi vpn-target

Function

The evi vpn-target command associates the EVI-RT extended community attributes of IGMP Join Synch routes with a BD.

The undo evi vpn-target command deletes the EVI-RT extended community attributes of IGMP Join Synch routes associated with a BD.

By default, the EVI-RT extended community attributes of IGMP Join Synch routes are not associated with a BD.

Format

evi vpn-target vrfRt [ vrfRtType ]

undo evi vpn-target vrfRt [ vrfRtType ]

Parameters

Parameter	Description	Value
vrfRt	Specifies an EVI VPN target added to VPN target lists of the EVPN instance address family for IGMP Join Synch routes.	vpn-target can be in any of the following formats: 2-byte AS number:4-byte user-defined number, for example, 1:3. The AS number is an integer ranging from 0 to 65535, and the user-defined number is an integer ranging from 0 to 4294967295. The AS number and user-defined number cannot both be 0s. Specifically, a VPN target cannot be 0:0. Integral 4-byte AS number:2-byte user-defined number, for example, 65537:3. The AS number ranges from 65536 to 4294967295, and the user-defined number ranges from 0 to 65535. 4-byte AS number in dotted notation:2-byte user-defined number, for example, 0.0:3 or 0.1:0. The 4-byte AS number in dotted notation is in the format of x.y, where x and y are integers that both range from 0 to 65535. The user-defined number ranges from 0 to 65535. The AS number and user-defined number cannot both be 0s. Specifically, a VPN target cannot be 0:0.0. 32-bit IP address:16-bit user-defined number, such as 192.168.122.15:1. The IP address ranges from 0.0.0.0 to 255.255.255.255, and the user-defined number ranges from 0 to 65535.
vrfRtType	Adds an EVI VPN target to specified VPN target lists of the EVPN instance address family.	This vlaue can be: export-extcommunity: Adds an EVI VPN target to the export VPN target list of the EVPN instance address family. import-extcommunity: Adds an EVI VPN target to the import VPN target list of the EVPN instance address family. both: Adds an EVI VPN target to both the import and export VPN target lists of the EVPN instance address family. If vrfRtType is not specified, both is used by default.

Integral 4-byte AS number:2-byte user-defined number, for example, 65537:3. The AS number ranges from 65536 to 4294967295, and the user-defined number ranges from 0 to 65535.
4-byte AS number in dotted notation:2-byte user-defined number, for example, 0.0:3 or 0.1:0. The 4-byte AS number in dotted notation is in the format of x.y, where x and y are integers that both range from 0 to 65535. The user-defined number ranges from 0 to 65535. The AS number and user-defined number cannot both be 0s. Specifically, a VPN target cannot be 0:0.0.
32-bit IP address:16-bit user-defined number, such as 192.168.122.15:1. The IP address ranges from 0.0.0.0 to 255.255.255.255, and the user-defined number ranges from 0 to 65535.

vrfRtType

This vlaue can be:

export-extcommunity: Adds an EVI VPN target to the export VPN target list of the EVPN instance address family.

import-extcommunity: Adds an EVI VPN target to the import VPN target list of the EVPN instance address family.

both: Adds an EVI VPN target to both the import and export VPN target lists of the EVPN instance address family. If vrfRtType is not specified, both is used by default.

Usage Guidelines

Usage Scenario

When IGMP snooping runs in a BD in an EVPN scenario, PEs synchronize IGMP signaling through BGP EVPN IGMP Join Synch routes. Each IGMP Join Synch route must carry a unique EVI-RT extended community attribute. To configure a unique EVI-RT extended community attribute in a BD, run the evi vpn-target command.

Prerequisites

IGMP signaling synchronization based on IGMP Join Synch routes has been enabled using the igmp-snooping signal-synch enable command in a BD.

Example

# Set an EVI VPN target added to both the import and export VPN target lists of the EVPN instance address family to 1:1 in BD 1.
