Configuring service loopback groups

A service loopback group contains one or multiple Ethernet ports for looping packets sent out by the device back to the device. This feature must work with other features, such as GRE.

A service loopback group provides one of the following services:

• Tunnel—Supports unicast tunnel traffic.

• Multicast tunnel—Supports multicast tunnel traffic.

• Multiport—Supports multiport ARP traffic.

The device supports only one service loopback group for each service type. You can use the service loopback group with multiple features.

Member ports in the service loopback group are load balanced.
