Configuring Intra-VLAN ND Proxies
Context
On an IPv6 network, if port isolation is configured in a VLAN, users in the VLAN cannot communicate with each other. Configure intra-VLAN ND proxies on the interfaces corresponding to the VLAN to enable Layer 3 communication among users.
In Figure 9-18, Host_1 and Host_2 belong to the same VLAN, but port isolation is configured between IF1 and IF2. Configure intra-VLAN ND proxies on the Switch so that Host_1 and Host_2 can communicate with each other.
Procedure
- Run the system-view command to enter the system view.
- Run the interface vlanif vlan-id command to enter the VLANIF interface view of the interface on which an intra-VLAN ND proxy is to be configured.
- Run the ipv6 enable command to enable the IPv6 function on the interface.
- Run the ipv6 address command to configure an IPv6 address for the interface. The IPv6 address must be in the same network segment as the IPv6 addresses of all hosts in the VLAN.
- Run the ipv6 nd proxy inner-access-vlan enable command to configure an intra-VLAN ND proxy on the VLANIF interface.
By default, the intra-VLAN ND proxy function is disabled.
In VLAN aggregation scenarios, if the ND proxy function is required in a sub-VLAN, configure intra-VLAN ND proxies on the VLANIF interfaces corresponding to the super-VLAN.
