Configuring the H.248/MGCP-based VAG Service

According to the data plan, configure  Huawei MA5600    standard VLAN 20 as the media and signaling upstream VLAN, add upstream port 0/19/0 to the VLAN, and configure the IP address of the Layer 3 interface to 10.10.10.10, which facilitates the configuration of the media and signaling IP address pools.
huawei(config)#vlan 20 standard
huawei(config)#port vlan 20 0/19 0
huawei(config)#interface vlanif 20
huawei(config-if-vlanif20)#ip address 10.10.10.10 24
huawei(config-if-vlanif20)#quit
Configure the media and signaling IP address pools.
Add the IP address of the VLAN Layer 3 interface configured in the previous step to the media and signaling IP address pools respectively. Therefore, the media and signaling IP addresses used for the services can be selected from the IP address pools. According to the data plan, IP address 10.10.10.10 is added to the media and signaling IP address pools, and the gateway IP address corresponding to the media IP address is 10.10.10.1.
huawei(config)#voip
huawei(config-voip)#ip address media 10.10.10.10 10.10.10.1
huawei(config-voip)#ip address signaling 10.10.10.10
huawei(config-voip)#quit
Add an MG interface.
Add an MG interface for the MG to communicate with the MGC, which ensures that the MGC can control the call connection through the MG interface. According to the data plan, add MG interface 0, and configure the interface attributes.
huawei(config)#interface h248 0
  Are you sure to add MG interface?(y/n)[n]:y
huawei(config-if-h248-0)#if-h248 attribute mg-media-ip1 10.10.10.10 mgip 10.10.10.10 mgport 2944 primary-mgc-ip1 10.10.20.20
primary-mgc-port 2944 code text transfer udp
Configure the TID template of the PSTN users on MG interface 0.
Configure the TID generation mode. According to the data plan, the terminal prefix of PSTN users is huawei, and the TID template adopts layering template 6.
 NOTICE:
The Huawei MA5683T   MA5603T/MA5608T requires that the terminal prefixes of PSTN users, ISDN BRA users, and ISDN PRA users on the same H.248 interface be either the same or different. Note this when configuring the terminal prefix.

Configuring a Role for the Interface

To ensure the normal forwarding of SEP packets in a SEP LS-S2326TP-EI-AC    segment, add Layer 2 interfaces to the SEP segment and configure different roles for the interfaces.

Run:
system-view
The system view is displayed.
Run:
interface interface-type interface-number
The view of an Ethernet interface added to the SEP segment is displayed.
Run:
stp disable
STP is disabled on the interface.
Run:
sep segment segment-id [ edge [ no-neighbor ] { primary | secondary } ]
The Ethernet interface is added to a specified SEP segment and a role is configured for it.
 NOTE:
On the S3300HI, an interface can be added to two SEP segments.
On the S3300SI and LS-S2326TP-SI-AC , an interface can be added to only one SEP segment.

Configuring the VLAN Associated with the Sub-interface

Perform the following steps on the ME60 that uses sub-interfaces to implement interworking in a VLAN.

This step is required when you enable proxy ARP in a VLAN on the Ethernet sub-interfaces, GE sub-interfaces, or Eth-Trunk sub-interfaces.To enable proxy ARP in a VLAN on the VLANIF interface, skip this step.

Run:

system-view

The system view is displayed.

Run:

interface { ethernet | gigabitethernet | eth-trunk } interface-number.sub-interface-number

The sub-interface view is displayed.

Run:

vlan-type dot1q low-vid

The Ethernet sub-interface is encapsulated with 802.1Q and the VLAN ID associated with the sub-interface is  ME60-X3    configured.

Configure the multicast service on MA5616

Create  MA5683T    VLANs.

huawei(config)#vlan 4002-4003 smart

Add the uplink port and the subtending port to the VLANs.

huawei(config)#port vlan 4002-4003 0/0 1

huawei(config)#port vlan 4002-4003 0/0 0

Configure multicast VLANs and the IGMP mode.

 NOTE:

The IGMP mode can be configured to IGMP proxy or IGMP snooping according to the requirements. In this example, the IGMP mode is IGMP proxy. If the planned IGMP mode is IGMP snooping, you can configure the IGMP snooping mode by running the igmp mode snooping command in multicast VLAN mode.

If configuring the IGMP mode fails, check whether the IGMP function is disabled. That is, the IGMP mode can be switched only when the IGMP function is disabled.

huawei(config)#multicast-vlan 4002

huawei(config-mvlan4002)#igmp mode proxy

  Are you sure to change IGMP mode?(y/n)[n]:y

huawei(config-mvlan4002)#multicast-vlan 4003

huawei(config-mvlan4003)#igmp mode proxy

  Are you sure to change IGMP mode?(y/n)[n]:y

Configure the multicast uplink port.

huawei(config-mvlan4003)#igmp uplink-port 0/0/1

huawei(config-mvlan4003)#multicast-vlan 4002

huawei(config-mvlan4002)#igmp uplink-port 0/0/1

Configure multicast programs.

 NOTE:

A multicast program can be configured statically or generated dynamically. In this example, the multicast program is configured statically.

In static configuration mode, you can run the igmp program add command to add multicast programs in batches. You cannot name a program, instead the system automatically names a program PROGRAM-M, in which M is the index of the added program.

huawei(config-mvlan4002)#igmp program add name program1 ip 224.1.1.1 sourceip 10.10.10.10

huawei(config-mvlan4002)#multicast-vlan 4003

huawei(config-mvlan4003)#igmp program add name program2 ip 224.1.1.2 sourceip 10.10.10.11

huawei(config-mvlan4003)#quit

Configure the multicast subtending port.

huawei(config)#btv

huawei(config-btv)#igmp cascade-port 0/0/0

Save the data.

huawei(config-btv)#quit

huawei(config  MA5600  )#save

Configuring a BGP Peer

Devices can exchange routing    ME60   information only after they have successfully set up a BGP peer relationship.

Run:

system-view

The system view is displayed.

Run:

bgp { as-number-plain | as-number-dot }

BGP is enabled, the local AS number is set, and the BGP view is displayed.

(Optional) Run:

router-id ipv4-address

The ID of a BGP router is set.

Run:

peer { ipv4-address | group-name } as-number { as-number-plain | as-number-dot }

The IP address and AS number of a remote peer are specified.

(Optional) Run:

peer { ipv4-address | group-name } connect-interface interface-type interface-number [ ipv4-source-address ]

The local interface and the source address used to set up a BGP connection are specified.

Run:

peer { ipv4-address | group-name } ebgp-max-hop [ hop-count ]

The maximum number of hops of an EBGP connection is set.

For details of BGP peers, refer to the HUAWEI NetEngine80E/40E Router Configuration Guide ME60-X3   - IP Routing.

Configuring a Signal Sending Delay on an Interface

When an interface on the ME60 is dual-homed to non-Huawei devices, configure a signal sending delay on the interface to avoid data loss due to asynchronous link switchover or incomplete configuration restoration.

When the ME60 configured with VRRP or E-APS services is dual-homed to non-Huawei devices, the ME60 cannot control traffic switchover between interfaces on the non-Huawei devices. In this case, link switchover on the ME60 is probably asynchronous with that on the non-Huawei devices. If the interface on the ME60 sends a signal immediately after being initialized, certain data is probably lost.

If an interface on the ME60 is directly connected to a non-Huawei device, when the ME60 is restarted, the interface sends a signal to the peer immediately after being initialized, which probably causes data loss before configurations of the ME60 are restored.

To prevent the problem, configure a signal sending delay on the ME60. 

Run:

system-view

The system view is displayed.

Run:

interface interface-type interface-number

The interface view is displayed.

Run:

port-tx-enabling-delay port-tx-delay-time

The signal sending delay function is ME60-X3    enabled and a signal sending delay is configured.
