set multicast tunnel enhanced
Function
The set multicast tunnel enhanced command allows an Eth-Trunk that works as a multicast VPN loopback interface to have member interfaces from different cards.
The undo set multicast tunnel enhanced command forbids an Eth-Trunk that works as a multicast VPN loopback interface to have member interfaces from different cards.
By default, an Eth-Trunk that works as a multicast VPN loopback interface cannot have member interfaces from different cards.
Format
set multicast tunnel enhanced
undo set multicast tunnel enhanced
This command is supported only on the S5720-EI, S5720-HI, S5730-HI, S5731-H, S5731-S, S5731S-H, S5731S-S, S5732-H, S6720-EI, S6720-HI, S6720S-EI, S6730-H, S6730S-H, S6730-S, and S6730S-S.
Usage Guidelines
Usage Scenario
When an Eth-Trunk that works as a multicast VPN loopback interface have member interfaces from different member switches in a stack system, multicast VPN services can function properly if the switch where a member interface is located fails. This improves device reliability.
Follow-up Procedure
Run the service type multicast-tunnel command to configure an Eth-Trunk as a multicast VPN loopback interface.
Configuration Impact
After the set multicast tunnel enhanced command is executed, the number of ACLs for multicast VPN will increase if the Eth-Trunk that functions as a multicast VPN loopback interface contains more than one member interface from a device. The number of ACLs equals to the number of interfaces on a device configured as the member interfaces of an Eth-Trunk functioning as a multicast VPN loopback interface multiplied by the number of Mtunnel outbound interfaces for accessing the public network. For example, if two interfaces on a device are configured as member interfaces of the Eth-Trunk functioning as a multicast VPN loopback interface, and if the device is configured with four Mtunnel outbound interfaces for accessing the public network, a total of eight (2*4) ACLs will be used by multicast VPN services. If there are insufficient ACL resources, multicast VPN services cannot run properly.
Precautions
A multicast VPN loopback interface cannot be configured together with the set multicast tunnel enhanced and undo set multicast tunnel enhanced commands.
