Predefined user roles
network-admin
Parameters
group-name: Specifies a peer group by its name, a case-sensitive string of 1 to 47 characters.
ipv4-address: Specifies a peer by its IPv4 address.
mask-length: Specifies a mask length in the range of 0 to 32. To specify a subnet, you must specify both the ipv4-address and mask-length arguments.
Usage guidelines
This command is exclusive with the peer next-hop-local command.
The next hop in BGP EVPN routes is the IP address of the originating VTEP. By default, the device replaces the next hop of IBGP routes with its address when advertising the routes to an EBGP peer. If the device is a transport network device, it will modify the next hop of BGP EVPN routes. For VTEPs to learn one another's IP address, you must configure the device to not change the next hop of routes advertised to EBGP peers.
Examples
# Configure the device to not change the next hop of routes advertised to EBGP peer 1.1.1.1.
<Sysname> system-view

Predefined user roles
network-admin
Parameters
route-distinguisher: Specifies an RD, a string of 3 to 21 characters. The RD cannot be all zeros and can use one of the following formats:
· 16-bit AS number:32-bit user-defined number. For example, 101:3.
· 32-bit IP address:16-bit user-defined number. For example, 192.168.122.15:1.
· 32-bit AS number:16-bit user-defined number. For example, 65536:1. The AS number must be equal to or greater than 65536.
auto: Automatically generates an RD in the N:VXLAN ID format. The initial value of N is 1. If N:VXLAN ID is already in use, the system increases the value of N by 1 until the RD is available.
Usage guidelines
EVPN uses MP-BGP to advertise EVPN routes for automatic VTEP discovery, MAC reachability information advertisement, and host route advertisement. MP-BGP uses the RD to differentiate EVPN routes of different EVPN instances.
Examples
# Configure 22:1 as the RD of an EVPN instance.

Predefined user roles
network-admin
Parameters
ext-comm-list-number: Specifies an extended community attribute list by its number in the range of 1 to 199.
Usage guidelines
This command enables an RR to reflect only received EVPN routes that match the attributes in the specified extended community attribute list.
If a cluster contains multiple RRs, you can configure different reflection policies on the RRs for load sharing among the RRs.
For more information about the extended community attribute list, see Layer 3—IP Routing Configuration Guide.
Examples
# Configure a reflection policy for the device to reflect BGP EVPN routes that match extended community attribute list 10.

Parameters
vpn-target&<1-8>: Specifies a space-separated list of up to eight route targets. Each route target is a string of 3 to 21 characters in one of the following formats:
· 16-bit AS number:32-bit user-defined number. For example, 101:3.
· 32-bit IP address:16-bit user-defined number. For example, 192.168.122.15:1.
· 32-bit AS number:16-bit user-defined number. For example, 65536:1. The AS number must be equal to or greater than 65536.
auto: Automatically generates a route target in the format of BGP AS number:VXLAN ID.
both: Uses the specified route targets as both import and export targets. If you do not specify the both, export-extcommunity, or import-extcommunity keyword, the both keyword applies.
import-extcommunity: Uses the specified route targets as import targets.
export-extcommunity: Uses the specified route targets as export targets.
all: Specifies all route targets.
Usage guidelines
EVPN uses MP-BGP to advertise EVPN routes for automatic VTEP discovery, MAC reachability information advertisement, and host route advertisement. MP-BGP uses route target attributes to control the advertisement and acceptance of EVPN routes.
A VTEP sets the export target attribute for EVPN routes before advertising the routes to remote VTEPs. The VTEP checks the export target attribute of EVPN routes from remote VTEPs and imports only EVPN routes of which the export target attribute matches the local import target attribute.
Examples
# Configure import route targets 10:1, 100:1, and 1000:1 for an EVPN instance.

· 32-bit AS number:16-bit user-defined number. For example, 65536:1. The AS number must be equal to or greater than 65536.
both: Uses the specified route targets as both import and export targets. If you do not specify the both, export-extcommunity, or import-extcommunity keyword, the both keyword applies.
import-extcommunity: Uses the specified route targets as import targets.
export-extcommunity: Uses the specified route targets as export targets.
all: Specifies all route targets.
Usage guidelines
A VTEP sets the export target attribute for EVPN routes before advertising the routes to remote VTEPs. The VTEP checks the export target attribute of EVPN routes from remote VTEPs and imports only EVPN routes of which the export target attribute matches the local import target attribute.
Route target attribute configuration made in VPN instance view applies to IPv4 VPN, IPv6 VPN, and EVPN. Route target attribute configuration made in EVPN view applies only to EVPN. Route target attribute configuration in EVPN view takes precedence over that in VPN instance view.
