Parameter
aggregation-group-id: Link aggregation group ID.
Description
Use the aggregation-group command to configure a service-loop group for a tunnel.
Use the undo aggregation-group command to remove the service-loop group configured for a tunnel.
By default, a tunnel does not reference any service-loop group.
Before configuring a service-loop group for a tunnel in tunnel interface view, you need to a configure link aggregation group in system view and set the service type of the link aggregation group to tunnel.
One tunnel interface can reference only one service-loop group.
For related configuration, refer to the link-aggregation group command. For details, refer to Port Correlation Configuration module.
Example
# Before configuring a service-loop group for a tunnel in tunnel interface view, create and configure link aggregation groups in system view. For example, create link aggregation group 1, and set the configuration mode to manual and the service type to tunnel.

Description
Use the expediting subnet command to set an IP address and mask for the expedite termination subnet.
Use the undo expediting subnet command to remove the configuration.
By default, no expedite termination subnet is configured for a tunnel.
Note that:
l You must enable the expedite termination before configuring an expedite termination subnet in tunnel interface view.
l The expediting subnet is not applicable to a manual tunnel (for example, IPv6 manually configured tunnel). After the expedite termination function is enabled, the system will automatically consider the destination address of a tunnel as the address of the expedite termination subnet, and the subnet mask as 255.255.255.255.
l For automatic tunnels (for example, automatic IPv4-compatible IPv6 tunnel, automatic 6to4 tunnel, and ISATAP tunnel), you must carry out the expediting subnet command to designate an IP address and subnet for the expedite termination subnet after carrying out the expediting enable command.
Example
# Configure an expedite termination subnet for an automatic 6to4 tunnel: First enable the expedite termination, and then set the address of the expedite termination subnet to 1.1.1.2 and the subnet mask to 255.255.255.0.
