Describes how to configure a password for a Huawei vswitch in MLS.

This article describes how to configure the password of A Huawei switch related to MLS settings. It is common to configure the password of A Huawei switch. However, how can we configure the password of A Huawei switch more accurately, what makes it easy to use?

To verify the MLS-RP of the Huawei Switch configuration password:
Router # show mls rp

Verify the configuration password of the MLS Huawei switch on a specific interface:
Router # show mls rp interface number

To set the stream mask on the MLS-SE and do not want to set the access list on any Route Processor interface:
Set mls flow [destination | destination-source | full]

To make the MLS compatible with the input access list, you can use the following commands in global mode:
Router (config) # mls rp ip input-acl

When the layer-3 Switch of A Huawei switch with a password fails, enter the following command in privileged mode:
Switch (enable) set mls enable

To change the value of the aging time, enter the following command in privileged mode:
Switch (enable) set mls agingtime

Quick password aging for Huawei Switch configuration:
Switch (enable) set mls agingtime fast fastagingtime pkt_threshold

Determine the MLS-RP and MLS-SE involved in the MLS, You can first display the contents of the Huawei Switch configuration password reference list and then confirm:
Switch (enable) show mls include

Show MLS cache records:
Switch (enable) show mls entry

Run the "show in arp ARP" command on the Huawei switch to display the content in the arp cache.

To configure a vro as a member of the HSRP backup group, run the following command in Interface Configuration Mode:
Router (config-if) # standby group-number ip address-address

To allow a vro to resume its role as a forwarding router, configure the password mode on the Huawei switch interface:
Router (config-if) # standy group-number preempt

The access time and retention time parameters are configurable:
Router (config-if) # standy group-number timers hellotime holdtime

HSRP tracking for configuring passwords for Huawei switches:
Router (config-if) # standy group-number track type-number interface-priority

To display the status of the HSRP router:
Router # show standby type-number group brief

Run the show ip igmp command to determine the queried server.

Start IP Multicast Route Selection:
Router (config) # ip muticast-routing

PIM on the startup interface:
Dalllasr1> (config-if) # ip pim {dense-mode | sparse-dense-mode}

Start the PIM in dense mode:
Router # ip multicast-routing
Router # interface type number
Router # ip pim sparse-dense-mode

Verify the password of the Huawei switch in PIM:
Dallasr1> # show ip pim interface [type number] [count]

Display PIM neighbors:
Dallasr1> # show ip neighbor type number

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

Select a default RP:
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

Use show ip pim neighbor to display the PIM neighbor table.

Display the configuration password records of each Huawei switch in the multicast communication route table:
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]
