How to set the TTL threshold in the configuration of Huawei Switches

How to set the TTL threshold value in the basic configuration of Huawei switches? A friend of mine recommended me to the detailed instance of the basic configuration of Huawei switches. I don't know the specific code. I hope the majority of users will give me some suggestions, preferably those who have passed the Huawei Switch configuration basics. Thank you.

To configure the RP address, run the following command:
Dallasr1> # ip pim rp-address ip-address [group-access-list-number] [override]

Select a default RP for the basic configuration of the Huawei switch:
Dallasr1> # ip pim rp-address
Advertise the RP and its service group scope:
Dallasr1> # ip pim send-rp-announce type number scope ttl group-list access-list-number
Advertise the RP address for the management range group:
Dallasr1> # ip pim send-rp-announce ethernet0 scope 16 group-list1
Dallasr1> # access-list 1 permit 266.0.0.0 0.20.255.255
Set an RP image Proxy:
Dallasr1> # ip pim send-rp-discovery scope ttl
Verify the image from the group to the RP:
Dallasr1> # show ip pim rp mapping
Dallasr1> # show ip pim rp [group-name | group-address] [mapping]

On the router interface, use the command ip multicast ttl-threshold ttl-value to set the TTL threshold value:
Dallasr1> (config-if) # ip multicast ttl-threshold ttl-value

Show ip pim neighbor is used to display the PIM neighbor table.

Each record in the multicast communication route table is displayed as follows:
Dallasr1> show ip mroute [group-name | group-address] [scoure] [summary] [count] [active kbps]

To record all IP multicast packets accepted and sent by a vro:
Dallasr1> # debug ip mpacket [detail] [access-list] [group]

To configure the basic configurations of A Huawei switch, you must configure cgmp on the cisco router:
Dallasr1> (config-if) # ip cgmp

Configure a multicast router to add it to a specific multicast group:
Dallasr1> (config-if) # ip igmp join-group-address

Huawei Switch configuration closes CGMP:
Dallasr1> (config-if) # no ip cgmp

CGMP on the basic startup switch of the Huawei Switch configuration:
Dallasr1> (enable) set cgmp enable
