track track-entry-number&<1-15>: Specifies a space-separated list of up to 15 track entry numbers in the range of 1 to 1024. The AC is up only if a minimum of one associated track entry is in positive state.

Usage guidelines

After you execute this command, packets received from the mapped Layer 3 interface or Ethernet service instance are forwarded to the PW or another AC bound to the cross-connect.

To configure this command for an Ethernet service instance, you must first use the encapsulation command to configure a frame match criterion for the Ethernet service instance.

The access mode determines how the PE treats the VLAN tag in Ethernet frames received from the AC. It also determines how the PE forwards Ethernet frames out of the AC.

· VLAN access mode—Ethernet frames received from the AC must carry a VLAN tag in the Ethernet header. The VLAN tag is called a P-tag, which is assigned by the service provider. Ethernet frames sent out of the AC must also carry the P-tag.

· Ethernet access mode—If Ethernet frames from the AC have a VLAN tag in the header, the VLAN tag is called a U-tag, and the PE ignores it. Ethernet frames sent out of the AC do not carry the P-tag.

Predefined user roles

network-admin

Parameters

aging aging-time: Specifies an aging timer in minutes for remote ARP entries, in the range of 60 to 1440. The default value is 60.

Usage guidelines

Use this command only on an EVPN network.

By default, the device issues a remote ARP entry to the hardware after the ARP information is advertised to the local site by BGP EVPN routes. This feature enables the device to issue a remote ARP entry to the hardware only when the entry is required for packet forwarding. This feature saves hardware resources on the device.

After you enable this feature, the device periodically examines whether the ARP entries are used for packet forwarding. An ARP entry is deleted if its aging timer expires.

When a large number of remote ARP entries exist, set an appropriate aging timer to avoid traffic interruption caused by the aging of ARP entries. As a best practice, set the aging timer value higher than or equal to the number of remote ARP entries divided by 200.

Examples

# Enable conversational learning for remote ARP entries and set the entry aging timer to 80 minutes.

Predefined user roles

network-admin

Usage guidelines

Local FRR enables two PEs at a multihomed EVPN VPWS network site to set up a bypass PW between them. This feature helps reduce the traffic loss caused by AC failure.

At a multihomed EVPN VPWS network site, CE 1 is dualhomed to PE 1 and PE 2, and PE 1 is the DF. When the AC on PE 1 fails, PE 1 advertises the local unreachable event to PE 2 and remote PEs for the remote PEs to switch traffic to the PWs to PE 2. In this situation, PE 1 drops the packets that the remote PEs send before they are notified of the local unreachable event. To resolve this issue, enable local FRR on PE 1 and PE 2. When receiving packets from the remote PEs after its AC fails, PE 1 forwards the packets to PE 2 over the bypass PW to prevent traffic loss.

On an EVPN instance, EVPN instance-specific local FRR configuration takes precedence over global local FRR configuration.

Predefined user roles

network-admin

Usage guidelines

Remote FRR enables two PEs on an EVPN VPWS network to set up a primary PW and a backup PW between them to ensure high availability. The PEs use the primary PW to forward traffic as long as it is available. When the primary PW fails, the PEs switch traffic to the backup PW.

On an EVPN instance, EVPN instance-specific remote FRR configuration takes precedence over global remote FRR configuration.

tunnel-policy tunnel-policy-name: Specifies a tunnel policy by its name, a case-sensitive string of 1 to 19 characters. If you do not specify a tunnel policy, the PW uses the default tunnel policy.

pw-class class-name: Specifies a PW class by its name, a case-sensitive string of 1 to 19 characters. You can specify a PW class to configure the PW data encapsulation type and control word for the PW. If you do not specify a PW class, the PW data encapsulation type is determined by the link type of the interface. The control word feature is not supported for PW data encapsulation types that do not require using control word.

Usage guidelines

You can use the evpn local-service-id remote-service-id command to concatenate two EVPN PWs on the same cross-connect.

To modify an EVPN PW, first use the undo evpn local-service-id remote-service-id command to delete the original EVPN PW.

Usage guidelines

This command enables devices to exchange the routes of a VPN instance by using IP prefix advertisement routes with MPLS encapsulation. After you execute this command for a VPN instance, the device advertises the routes of the VPN instance through IP prefix advertisement routes. When receiving IP prefix advertisement routes with MPLS encapsulation, the device adds the routes that belong to the VPN instance to the routing table.

For EVPN to add MPLS encapsulation to IP prefix advertisement routes, you must execute the peer advertise encap-type mpls command in BGP EVPN address family view.

Examples

# Enable EVPN to advertise the IPv4 routes of VPN instance vpna.

Views

System view

Predefined user roles

network-admin

Usage guidelines

This command is available only in the EVPN VPLS multihoming scenario. Use this command on the redundant PEs at a dualhomed site.

This command enables the device to do the following:

· Withdraw the Ethernet auto-discovery routes and MAC/IP advertisement routes that have been advertised.

· Set the Ethernet tag to 0 for the Ethernet auto-discovery routes and MAC/IP advertisement routes and re-advertise them.

After you configure ESIs for ACs on the redundant edge devices at a dualhomed site, the edge devices advertise Ethernet auto-discovery routes and MAC/IP advertisement routes that carry Ethernet tags. If the remote peers are unable to identify Ethernet tags, you must execute this command on the redundant edge devices to enable communication with the peers.

When you use this command, follow these restrictions and guidelines:

· After you assign an ESI to a Layer 2 Ethernet or aggregate interface, you must map the Ethernet service instances created on the interface to different VSIs. If two interfaces use the same ESI, you must map the Ethernet service instances created on them to different VSIs.

· After you assign an ESI to a Layer 3 main interface, its subinterfaces inherit the ESI if they do not have one. In addition, you must map two subinterfaces to different VSIs if the subinterfaces have the same ESI.

Examples

# Enable the device to ignore the Ethernet tag when advertising Ethernet auto-discovery routes and MAC/IP advertisement routes.

Parameters

all-active: Specifies the all-active mode.

single-active: Specifies the single-active mode.

Usage guidelines

This command is supported only by a multihomed EVPN VPWS network.

The redundant PEs at a dualhomed site each establish an EVPN PW to a remote PE. To use one PW as a backup of the other PW, use the single-active mode. To distribute traffic across the PWs for load sharing, use the all-active mode.

As a best practice, set the same redundancy mode on the interfaces that act as ACs or are configured with ACs on the redundant PEs at a multihomed site.

Make sure the interface where you execute this command is assigned an ESI.

Examples

# Set the redundancy mode to single-active on HundredGigE 1/0/1.

network-admin

Parameters

delay-time: Specifies a delay value in the range of 3 to 1200 seconds.

Usage guidelines

The advertisement delay timer for Ethernet auto-discovery routes helps reduce the traffic loss caused by a PE reboot at a multihomed EVPN VPLS network site.

At a multihomed EVPN VPLS network site, CE 1 is dualhomed to PE 1 and PE 2 through an aggregate link or smart trunk, and PE 3 is at a remote site. PE 1 forwards all traffic sent from CE 1 to the remote site, and PE 3 forwards the traffic that the remote site sends to CE 1 to both PE 1 and PE 2. When PE 1 reboots, it advertises Ethernet auto-discovery routes that carry next hop information to PE 3. If PE 3 has not received the MAC/IP advertisement routes advertised by PE 2 when receiving the Ethernet auto-discovery routes, it will forward traffic to both PE 1 and PE 2. In this situation, PE 1 does not have MAC address entries for CE 1 and drops the traffic.

To resolve this issue, set the advertisement delay timer for Ethernet auto-discovery routes on the CE-facing interface of PE 1. This timer allows PE 3 to receive the MAC/IP advertisement routes advertised by PE 2 before the Ethernet auto-discovery routes advertised by PE 1 and update its MAC address table timely.

Examples

# On HundredGigE 1/0/1, set the advertisement delay timer for Ethernet auto-discovery routes to 300 seconds.

network-admin

Parameters

peer-address: Specifies a PE by its IPv4 address.

Usage guidelines

Use this command on the CE-facing interfaces of the edge devices multihomed to a site to prevent device reboots from causing inter-site forwarding failure.

This command excludes unavailable edge devices from DF election at a multihomed site. After an edge device recovers from failure and brings up its CE-facing interface, it starts a delay timer and checks the status of the BGP peer specified in this command. If the BGP peer comes up before the timer expires, the edge device advertises Ethernet segment routes to the peer. If the BGP peer is still down when the timer expires, the edge device does not advertise Ethernet segment routes to the peer. The edge devices then perform DF election based on the Ethernet segment routes they have received.

Examples

# On HundredGigE 1/0/1, enable the device to monitor the BGP peer at 1.1.1.1.

Parameters

session-name: Specifies a static BFD session name, a case-sensitive string of 1 to 15 characters.

Usage guidelines

Use this command on a BDF for fast DF/BDF switchover.

At a multihomed site of an EVPN VPWS network, a BDF cannot take over the DF role immediately when an AC on a DF fails, and traffic loss will occur as a result. To resolve this issue, set up a static BFD session between the DF and BDF. You must configure the static BFD session to monitor the status of the local AC on the DF and enable the BDF to monitor the status of the session. When the AC on the DF fails, the static BFD session goes down, and the BDF can fast take over the DF role to reduce traffic loss.

To modify the static BFD session monitored on an interface, first use the undo evpn track bfd command to remove the existing static BFD session configuration.

Examples

# Enable the device to monitor the status of static BFD session abc on HundredGigE 1/0/1 for fast DF/BDF switchover.

route-policy: Specifies a routing policy by its name, a case-sensitive string of 1 to 63 characters.

Usage guidelines

You can specify an export routing policy to filter advertised routes or modify their route attributes for EVPN.

If you execute this command multiple times, the most recent configuration takes effect.

EVPN can use an export routing policy specified in VPN instance view or in VPN instance EVPN view. Export routing policy configuration in VPN instance EVPN view takes precedence over that in VPN instance view.

Examples

# Apply export routing policy poly-1 to EVPN on VPN instance vpn1.

<Sysname> system-view

[Sysname] ip vpn-instance vpn1

[Sysname-vpn-instance-vpn1] address-family evpn

[Sysname-vpn-evpn-vpn1] export route-policy poly-1

Usage guidelines

This command helps reduce the traffic loss caused by AC failure at a multihomed EVPN VPLS network site that uses single-active redundancy mode.

At a multihomed EVPN VPLS network site that uses single-active redundancy mode, CE 1 is dualhomed to PE 1 and PE 2 through a smart trunk. PE 1 is the primary PE, and PE 2 is the secondary PE. When the AC on PE 1 fails, PE 1 and PE 2 act as follows:

· PE 1 withdraws advertised Ethernet auto-discovery routes.

· PE 2 brings up its AC and advertises Ethernet auto-discovery routes to remote PEs.

The remote PEs switch traffic to the paths to PE 2 only after receiving the Ethernet auto-discovery routes advertised by PE 2, and traffic loss occurs during path switchover. To resolve this issue, enable VSIs to ignore the state of ACs on PE 2. This feature allows PE 2 to advertise Ethernet auto-discovery routes to remote PEs regardless of the state of ACs and speeds up path switchover when the AC on PE 1 fails.

On a VSI, VSI-specific AC state ignore configuration takes precedence over global AC state ignore configuration.

Examples

# Enable VSI vpna to ignore the state of ACs.

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 router-id: Automatically generates an RD based on the router ID in the Router ID:N format. The initial value of N is 1. If Router ID:N 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 BGP EVPN routes for automatic PE discovery, MAC reachability information advertisement, and host route advertisement. MP-BGP uses the RD to differentiate BGP EVPN routes of different EVPN instances.

To modify an RD, first execute the undo route-distinguisher command to remove the original RD.

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.

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.

export-extcommunity: Uses the specified route targets as export targets.

import-extcommunity: Uses the specified route targets as import targets.

all: Specifies all route targets.

Usage guidelines

EVPN uses MP-BGP to advertise BGP EVPN routes for automatic PE discovery, MAC reachability information advertisement, and host route advertisement. MP-BGP uses route targets to control the advertisement and acceptance of BGP EVPN routes.

A PE sets the export targets for BGP EVPN routes before advertising the routes to remote PEs. The PE checks the export targets of BGP EVPN routes from remote PEs and imports only BGP EVPN routes of which the export targets match the local import targets.

If you execute this command multiple times, all configured route targets take effect.

Examples

# Configure import route targets 10:1, 100:1, and 1000:1 for an EVPN instance.
