Huawei quidway s7700 - Optional) Setting Switching Parameters of Switch-MDT

No. Data
1 VPN instance name
2 The address range and mask of the switch-group-pool of Switch-MDT
3 Switching threshold
4 Delay for switching from Share-MDT to Switch-MDT
5 Delay for switching from Switch-MDT to Share-MDT
8.4.2 (Optional) Setting Switching Parameters of Switch-MDT
To reduce the burden on the PE and save bandwidth resources, you can establish a switch-MDT
for multicast data packets flowing from the VPN to the public network and switch the multicast
data packets from the share-MDT to the switch-MDT.
Context
Do as follows on the PE switch:
NOTE
This configuration is optional. If this configuration is not done, Switch-MDT switchover cannot be
performed and Share-MDT is always used to transmit VPN multicast data.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
ip vpn-instance vpn-instance-name
The VPN instance view is displayed.
Step 3 Run:
multicast-domain switch-group-pool switch-group-pool { network-mask | network-mask-
length } [ threshold threshold-value | acl { advanced-acl-number | acl-name } ] *
The switch-group-pools of Switch-MDT and switch conditions are configured.
The parameters of the command are explained as follows:
l switch-group-pool: specifies a switch-group-pool. It's suggested that the same VPN instance
on different PEs are configured with the same switch-group-pool. On a PE, the Switch-Group
address ranges to which different VPNs correspond cannot overlap.
l threshold-value: Specifies the threshed. By default, it is 0 kbit/s.
l { advanced-acl-number | acl-name }: specifies the advanced ACL filtering rules. By default,
packets are not filtered.
Step 4 (Optional) Run:
multicast-domain switch-delay switch-delay
