SAVI configuration in SLAAC-only address
assignment scenario
Network requirements
Figure 135 Network diagram
As shown in Figure 135, Switch A serves as the gateway. Switch B connects Host A and Host B. The hosts
can obtain IPv6 addresses only through SLAAC. Configure SAVI on Switch B to bind the addresses
assigned through SLAAC and permit only packets from the bound addresses.
Configuration considerations
Configure Switch B as follows:
1. Enable SAVI.
2. Enable global unicast address ND snooping and link-local address ND snooping. For more
information about ND snooping, see Layer 3—IP Services Configuration Guide.
3. Enable ND detection in VLAN 10 to check the ND packets arrived on the ports. For more
information about ND detection, see "Configuring ND attack defense."
