(Optional) Enabling Proxy ARP on the VLANIF Interface of a Super-VLAN
Context
VLAN aggregation does not support Layer 3 communication between hosts in different sub-VLANs.
To enable hosts in one sub-VLAN to communicate with hosts in another sub-VLAN or on another network over Layer 3, enable proxy ARP.
After a super-VLAN and its VLANIF interface are created, proxy ARP must be enabled to allow the super-VLAN to forward or process ARP request and reply packets. Proxy ARP helps PCs in sub-VLANs communicate with each other at the network layer.
Procedure
- Run system-view
The system view is displayed.
- Run interface vlanif vlan-id
The view of the VLANIF interface of the super-VLAN is displayed.
- Run arp proxy inter-vlan enable
Inter-sub-VLAN proxy ARP is enabled.
An IP address must have been assigned to the VLANIF interface corresponding to the super-VLAN. Otherwise, proxy ARP cannot take effect.
- Run commit
The configuration is committed.
