gre checksum
Use gre checksum to enable GRE checksum.
Use undo gre checksum to disable GRE checksum.
Syntax

undo gre checksum
Default
GRE checksum is disabled.
Views

Predefined user roles
network-admin
Usage guidelines
GRE checksum verifies packet integrity.
You can enable or disable GRE checksum at each end of a tunnel as needed. After GRE checksum is enabled, the sender does the following:
· Calculates the checksum for the GRE header and the payload.
· Sends the packet containing the checksum information to the peer.
The receiver calculates the checksum for the received packet and compares it with that carried in the packet. If the checksums are the same, the receiver processes the packet. If the checksums are different, the receiver discards the packet.
If a packet carries a GRE checksum, the receiver checks the checksum whether or not the receiver is enabled with GRE checksum.
Examples
# Enable GRE checksum.

Predefined user roles
network-admin
Parameters
key: Specifies the key for the GRE tunnel interface, in the range of 0 to 4294967295.
Usage guidelines
Both ends of a GRE point-to-point tunnel must have the same key or no key.
Do not configure any GRE key on a GRE P2MP tunnel interface. You can configure GRE keys on the GRE tunnel interfaces in the branch networks. The GRE keys not only check for the validity of packets received on the tunnel interfaces but also indicate the priorities of dynamic tunnels. The GRE P2MP tunnel end prefers the branch tunnel that has the highest priority to forward traffic.
If a GRE P2MP tunnel is set up based on static tunnel entries, do not configure GRE keys on the GRE tunnel interfaces in the branch networks.
Examples
# Configure the GRE key as 123 for the GRE tunnel interface Tunnel 2.
<Sysname> system-view
[Sysname] interface tunnel 2 mode gre
[Sysname-Tunnel2] gre key 123
gre p2mp aging-time
Use gre p2mp aging-time to specify an aging timer for dynamic tunnel entries of a GRE P2MP tunnel interface.
Use undo gre p2mp aging-time to restore the default.
Syntax
gre p2mp aging-time aging-time
undo gre p2mp aging-time
Default
The aging timer is 5 seconds.
Views
Tunnel interface view
Predefined user roles
network-admin
Parameters
aging-time: Specifies an aging timer in the range of 1 to 86400 seconds.
Usage guidelines
This command is applicable only to GRE P2MP tunnel interfaces.
If the headquarters gateway does not receive any packets from a branch when the aging timer expires, it deletes the dynamic tunnel entry of that branch.
Set an appropriate aging timer depending on the network condition. A shorter timer might cause forwarding failure to an actual reachable network. A longer timer cannot quickly update dynamic tunnel entries.
Examples
# Set the aging timer to 10 seconds for dynamic tunnel entry on GRE P2MP tunnel interface Tunnel 0.
<Sysname> system-view
[Sysname] interface tunnel 0 mode gre-p2mp
[Sysname-Tunnel0] gre p2mp aging-time 10
gre p2mp backup-interface
Use gre p2mp backup-interface to specify a backup interface for a GRE P2MP tunnel interface.
Use undo gre p2mp backup-interface to restore the default.
Syntax
gre p2mp backup-interface tunnel number
undo gre p2mp backup-interface
Default
No backup interface is configured for a GRE P2MP tunnel interface.
Views
Tunnel interface view
Predefined user roles
network-admin
Parameters
tunnel number: Specifies a tunnel interface by its interface number. The tunnel interface must exist on the device and must be a GRE/IPv4 or GRE/IPv6 tunnel interface.
Usage guidelines
This command is applicable only to GRE P2MP tunnel interfaces.
When the device cannot find a matching GRE P2MP dynamic tunnel entry to forward traffic, it forwards the traffic to the backup gateway through the backup interface. Services (for example, NetStream and NAT) on the backup interface do not take effect on the traffic. The service configuration on the primary GRE P2MP tunnel interface is used for the traffic.
Examples
# Specify tunnel interface Tunnel 100 as the backup interface of GRE P2MP tunnel interface Tunnel 0.
<Sysname> system-view
[Sysname] interface tunnel 0 mode gre-p2mp
[Sysname-Tunnel0] gre p2mp backup-interface tunnel 100
gre p2mp branch-network-mask
Use gre p2mp branch-network-mask to specify the network mask or mask length for IPv4 branch networks or specify the prefix length for IPv6 branch networks on a GRE P2MP tunnel interface.
Use undo gre p2mp branch-network-mask to restore the default.
Syntax
gre p2mp branch-network-mask { mask | mask-length | ipv6 prefix-length }
undo gre p2mp branch-network-mask [ ipv6 ]
Default
The IPv4 address mask is 255.255.255.255 (the mask length is 32) and the IPv6 address prefix length is 128 for branch networks.
Views

Predefined user roles
network-admin
Parameters
mask: Specifies the IPv4 address mask, in dotted decimal notation.
mask-length: Specifies the IPv4 address mask length, in the range of 0 to 32.
ipv6 prefix-length: Specifies the IPv6 address prefix length, in the range of 0 to 128.
Usage guidelines
This command is applicable only to GRE P2MP tunnel interfaces.
This command enables a GRE P2MP tunnel interface to use the same network mask or prefix length to create dynamic tunnel entries for branch networks. One branch has only one dynamic tunnel entry.
To ensure successful packet forwarding, make sure all branch networks have the same network mask or prefix length, which is the same as that specified by this command.
Examples
# Specify the IPv4 branch network mask as 255.255.255.0 for GRE P2MP dynamic tunnel entries on tunnel interface Tunnel 0.

gre vpc enable
Use gre vpc enable to enable GRE packets to carry virtual private cloud (VPC) information.
Use undo gre vpc enable to disable GRE packets from carrying VPC information.
Syntax
gre vpc enable
undo gre vpc enable
Default
GRE packets do not carry VPC information.
Views
Tunnel interface view
Predefined user roles
network-admin
Usage guidelines
Enable this feature for a GRE tunnel in a VPC network. After receiving a packet carrying VPN information, the source end of the GRE tunnel transforms the VPN information into a VPCID and then forwards the packet. After the destination end of the GRE tunnel receives the packet, it transforms the VPCID into VPN information and then forwards the packet to the VPN.
In a VPC network, the VPN name must be a number. Otherwise, the VPN information cannot be transformed into a VPCID.
Do not use this command together with the gre key command on the same tunnel interface.
Examples
# Enable GRE packets to carry VPC information.

keepalive
Use keepalive to enable GRE keepalive and set the keepalive interval and the keepalive number.
Use undo keepalive to disable GRE keepalive.
Syntax
keepalive [ interval [ times ] ]
undo keepalive
Default
GRE 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 GRE keepalive is enabled.
GRE/IPv6 mode tunnel interfaces do not support this command.
Examples
# Enable GRE keepalive, set the keepalive interval to 20 seconds, and set the keepalive number to 5.
<Sysname> system-view
[Sysname] interface tunnel 2 mode gre
[Sysname-Tunnel2] keepalive 20 5
map
Use map to configure a tunnel mapping entry in a GRE/IPv4 P2MP tunnel template.
Use undo map to delete a tunnel mapping entry from a GRE/IPv4 P2MP tunnel template.
Syntax
map [ vpn-instance vpn-instance-name ] branch-network-address branch-network-address { mask | mask-length } tunnel-destination tunnel-dest-address [ checksum-fill checksum-value ]
undo map [ vpn-instance vpn-instance-name ] branch-network-address branch-network-address { mask | mask-length } [ tunnel-destination tunnel-dest-address ]

Parameters
vpn-instance vpn-instance-name: Specifies an MPLS L3VPN instance by its name. The vpn-instance-name argument is a case-sensitive string of 1 to 31 characters. If the branch network address belongs to a private network, you must specify this option. If the branch network address belongs to the public network, do not specify this option.
branch-network-address branch-network-address: Specifies an IPv4 branch network address.
mask: Specifies the mask of the branch network address, in dotted decimal notation.
mask-length: Specifies the mask length of the branch network address, in the range of 0 to 32.
tunnel-destination tunnel-dest-address: Specifies the tunnel destination IPv4 address.
checksum-fill checksum-value: Specifies an IPv4 address to fill in the checksum field of the GRE header. The IPv4 address is in dotted decimal notation. If you do not specify this option, the device does not fill in the checksum field of the GRE header.
Usage guidelines
The tunnel mapping entries in the tunnel template are static tunnel entries.
You can repeat this command to configure multiple tunnel mapping entries for a GRE/IPv4 P2MP tunnel template. Each entry defines a mapping between a branch network address and a tunnel destination address. One branch network address can be mapped to only one tunnel destination address.
If a branch network contains VMs that have multiple users, fill the IPv4 address of the destination VM to the checksum field for correct forwarding of a GRE packet. Specify the checksum-fill checksum-value option depending on your network. Incorrect usage of the option will cause GRE checksum failures.
Examples
# In GRE/IPv4 P2MP tunnel template aa, configure a tunnel mapping entry. The branch network address is 192.168.0.11 and the mask length is 32, the tunnel destination address is 10.108.113.71, and the IPv4 address to fill in the checksum field is 192.168.20.1.
