Disabling router advertisement and solicitation messages
Router advertisement and solicitation messages enable a node on a link to discover the routers on the same link. By default, router
advertisement and solicitation messages are permitted on the device. To disable these messages,
congure an IPv6 access control list
that denies them. The following shows an example conguration.
device(config)#ipv6 access-list rtradvert
device(config)#deny icmp any any router-advertisement
device(config)#deny icmp any any router-solicitation
device(config)#permit ipv6 any any
