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 1/2
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-Ethernet1/2)# ipv6 security-ra enable
