Parameters

ipv4-address: Specifies the tunnel destination IPv4 address.

Usage guidelines

The tunnel destination address must be the address of the receiving interface on the tunnel peer. It is used as the destination address of tunneled packets.

The destination address of the local tunnel interface must be the source address of the peer tunnel interface. The source address of the local tunnel interface must be the destination address of the peer tunnel interface.

Do not specify the same tunnel source and destination addresses for the tunnel interfaces on the same device.

Examples

# The interface on Sysname 1 uses IP address 193.101.1.1 and the interface on Sysname 2 uses IP address 192.100.1.1. Configure the source address 193.101.1.1 and destination address 192.100.1.1 for the tunnel interface on Sysname 1.

eogre udp-port

Use eogre udp-port to configure the destination UDP port number of EoGRE packets.

Use undo eogre udp-port to restore the default.

Syntax

eogre udp-port port-number

undo eogre udp-port

Default

The destination UDP port number of EoGRE packets is 4754.

Views

EoGRE tunnel interface view

Predefined user roles

network-admin

Parameters

port-number: Sets the destination UDP port number of EoGRE packets, in the range of 1 to 65535. As a best practice, do not configure this port number as a known port number (1 to 1023).

Usage guidelines

Use this command to configure the destination UDP port number for outgoing EoGRE packets to be encapsulated by UDP on an EoGRE tunnel.

The UDP port number of EoGRE packets specified in this command cannot be a port number that has been used by other modules (such as VXLAN) or tunnels.

An EoGRE tunnel interface can configure only one destination UDP port number for EoGRE packets. On the same device, you can configure a maximum of 32 destination UDP port numbers for EoGRE packets in addition to the default one.

Examples

# On EoGRE tunnel interface 0, set the destination UDP port number of EoGRE packets to 4755.

<Sysname> system-view

[Sysname] interface tunnel 0 mode eogre

[Sysname-Tunnel0] eogre udp-port 4755

# In EoGRE template abc, set the destination UDP port number of EoGRE packets to 4755.

<Sysname> system-view

[Sysname] eogre template abc

[Sysname-eogre-template-abc] eogre udp-port 4755

keepalive

Use keepalive to enable EoGRE keepalive and set the keepalive interval and the keepalive number, and configure the keepalive mode.

Use undo keepalive to disable EoGRE keepalive.

Syntax

keepalive [ interval [ times ] ]*

undo keepalive

Default

EoGRE keepalive is disabled.

Views

Tunnel interface view

Predefined user roles

network-admin

Parameters

interval: Specifies the keepalive interval, in the range of 1 to 32767 seconds. The default value is 10.

times: Specifies the keepalive number, in the range of 1 to 255. The default value is 3.

Usage guidelines

This command enables the tunnel interface to send keepalive packets at the specified interval. If the device receives no response from the peer within the timeout time, it shuts down the local tunnel interface. The device brings the local tunnel interface up if it receives a keepalive acknowledgment packet from the peer. The timeout time is the result of multiplying the keepalive interval by the keepalive number.

The device always acknowledges the keepalive packets it receives whether or not keepalive is enabled.

Examples

# Enable EoGRE keepalive, set the keepalive interval to 20 seconds, and set the keepalive number to 5.

<Sysname> system-view

[Sysname] interface tunnel 2 mode eogre

[Sysname-Tunnel2] keepalive 20 5

map bridge

Use map bridge to map a Layer 2 VEB interface to an EoGRE tunnel interface or a Layer 3 physical interface.

Use undo map bridge to remove the mapping.

Syntax

map bridge { ve-bridge number | ve-bridge name }

undo map bridge

Default

No VEB interface is mapped to an EoGRE tunnel interface or a Layer 3 physical interface.

Views

EoGRE tunnel interface view

Layer 3 physical interface view

Predefined user roles

network-admin

Parameters

ve-bridge number: Specifies an existing Layer 2 VEB interface by its number.

ve-bridge name: Specifies an existing Layer 2 VEB interface by its name.

Usage guidelines

Before you use an EoGRE tunnel interface, you must execute this command to bind the EoGRE tunnel interface to a Layer 2 VEB interface.

Packets sent by the Layer 2 VEB interface are passed to the mapped EoGRE tunnel interface for encapsulation and forwarding.

To ensure successful mapping, a Layer 2 VEB interface mapped to an EoGRE tunnel interface cannot be bound to other services (such as ATM).

Examples

# Enter Layer 3 physical interface view and map Layer 2 VEB interface VE-Bridge 1/0/1 to the Layer 3 physical interface.

<Sysname> system-view

[Sysname] interface gigabitethernet 1/0/1

[Sysname-GigabitEthernet1/0/1] map bridge ve-bridge 1/0/1

# Create EoGRE-mode tunnel interface Tunnel 0, enter tunnel interface view, and map VE-Bridge 1 to Tunnel 0.

<Sysname> system-view

[Sysname] interface tunnel 0 mode eogre

[Sysname-Tunnel0] map bridge ve-bridge 1

mtu

Use mtu to set the MTU on a tunnel interface.

Use undo mtu to restore the default.

Syntax

mtu size

undo mtu

Default

If the tunnel interface has never been up, the MTU of the tunnel interface is 64000 bytes.

If the tunnel interface is up, its MTU is identical to the outgoing interface's MTU minus the length of the tunnel headers. The outgoing interface is automatically obtained through routing table lookup based on the tunnel destination address.

Views

Tunnel interface view

Predefined user roles

network-admin

Parameters

size: Specifies the MTU in the range of 100 to 64000 bytes.

Usage guidelines

If you do not configure an MTU for a tunnel interface, the effective MTU depends on the tunnel interface status.

·     If the tunnel interface is up, its MTU is identical to the outgoing interface's MTU minus the length of the tunnel headers.

·     If the tunnel interface is down, the device does not calculate or update the MTU of the tunnel interface.

If you configure an MTU for a tunnel interface, the configured MTU applies regardless of the tunnel interface status (up/down) and the outgoing interface MTU.

To avoid fragmentation after tunnel encapsulation, set the tunnel interface MTU no greater than the value of the outgoing interface MTU minus the length of the tunnel headers.

Examples

# Set the MTU on Tunnel 1 to 10000 bytes.

<Sysname> system-view

[Sysname] interface tunnel 1

[Sysname-Tunnel1] mtu 1000

Related commands

display interface tunnel

source

Use source to specify the source address or source interface for a tunnel interface.

Use undo source to restore the default.

Syntax

source { ipv4-address | interface-type interface-number }

undo source

Default

No source address or source interface is specified for a tunnel interface.

Views

Tunnel interface view

Predefined user roles

network-admin

Parameters

ipv4-address: Specifies the tunnel source IPv4 address.

interface-type interface-number: Specifies the source interface by its type and number. The interface must be up and must have an IP address.

Usage guidelines

The specified source address or the address of the specified source interface is used as the source address of tunneled packets. To display the configured tunnel source address, use the display interface tunnel command.

Do not specify the same tunnel source and destination addresses for the tunnel interfaces on the same device.

The destination address of the local tunnel interface must be the source address of the peer tunnel interface. The source address of the local tunnel interface must be the destination address of the peer tunnel interface.

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

Examples

# Specify the source interface for Tunnel 1 as VLAN-interface 10.

<Sysname> system-view

[Sysname] interface tunnel 1

[Sysname-Tunnel1] source vlan-interface 10

# Specify the source address of Tunnel 1 as 192.100.1.1.
