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, configure an IPv6 access control list that denies them. The following shows an
example configuration.

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

Disabling IPv6 on a Layer 2 switch

IPv6 is enabled by default in the Layer 2 switch code. If desired, you can disable IPv6 on a global basis
on a device running the switch code. To do so, enter the following command at the Global CONFIG
level of the CLI.

device(config)#no ipv6 enable

Syntax: no ipv6 enable

To re-enable IPv6 after it has been disabled, enter ipv6 enable .
