IPv6 Security RA Typical Examples
Fig 53-1 IPv6 Security RA sketch map
Instructions: if the illegal user in the graph advertises RA, the normal user will receive
the RA, set the default router as the vicious IPv6 host user and change its own address.
This will cause the normal user to not be able to connect the network. We want to set
security RA on the 1/0/2 port of the switch, so that the RA from the illegal user will not
affect the normal user.
Switch configuration task sequence:
Switch#config
Switch(config)#ipv6 security-ra enable
Switch(Config-If-Ethernet1/0/2)# ipv6 security-ra enable
