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.

Example

Brocade(config)#ipv6 access-list rtradvert

Brocade(config)#deny icmp any any router-advertisement

Brocade(config)#deny icmp any any router-solicitation

Brocade(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.

Brocade(config)#no ipv6 enable

Syntax: no ipv6 enable

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

NOTE

IPv6 is disabled by default in the router code and must be configured on each interface that will
support IPv6.

Static IPv6 route configuration

NOTE

Static IPv6 route configuration is supported only with the IPv6 Layer 3 PROM and the full Layer 3
image.

You can configure a static IPv6 route to be redistributed into a routing protocol, but you cannot
redistribute routes learned by a routing protocol into the static IPv6 routing table.
