RADIUS-Based Configuration

You can use RADIUS attribute Ipv6-NdRa-Prefix (VSA 26-129) to configure the prefix used in IPv6 Neighbor Discovery route advertisements. RADIUS then includes the VSA in Access-Accept messages. For information about the Ipv6-NdRa-Prefix RADIUS attribute, see Configuring RADIUS Attributes and RADIUS Attribute Descriptions in the JUNOSe Broadband Access Configuration Guide. .

ipv6 nd

• Use to enable the IPv6 Neighbor Discovery process on an interface.

• Example

  host1(config)#interface fastEthernet 3/0

  host1(config-if)#ipv6 nd

• Use the no version of this command to disable the Neighbor Discovery process.
• See ipv6 nd

ipv6 nd active-solicitations

• Use to specify that the router actively solicit neighbors that become stale (inactive). Normally, when a neighbor entry goes from a reachable state to a stale state, the router drops traffic until it resolves this neighbor entry. When enabled, the ipv6 nd active-solicitations command allows the router to use the stale neighbor entry while it solicits the neighbor. If the neighbor solicitation fails, the router removes the entry from the neighbor table and does not use the neighbor to forward any traffic.

• Example

  host1(config-if)#ipv6 nd active-solicitations

• Use the no version of this command to disable active solicitations.
• See ipv6 nd active-solicitations

ipv6 nd managed-config-flag

• Use to set the “managed address configuration” flag in IPv6 router advertisements.

• Example

  host1(config-if)#ipv6 nd managed-config-flag

• Use the no version of this command to clear the flag from IPv6 router advertisements.
• See ipv6 nd managed-config-flag

ipv6 nd ns-interval

• Use to specify the interval, in milliseconds, between IPv6 neighbor solicitation retransmissions on an interface.

• Example

  host1(config-if)#ipv6 nd ns-interval 500

• Use the no version of this command to return the interval between neighbor solicitation retransmission to its default value (zero [0] milliseconds for router advertisements and 1000 milliseconds for Neighbor Discovery activity of the E-series router).
• See ipv6 nd ns-interval.

ipv6 nd other-config-flag

• Use to set the “other stateful configuration” flag in IPv6 router advertisements.

• Example

  host1(config-if)#ipv6 nd other-config-flag

• Use the no version of this command to clear the flag from IPv6 router advertisements.
• See ipv6 nd other-config-flag

ipv6 nd prefix-advertisement

• Use to specify which IPv6 prefixes the system includes in IPv6 router advertisements.

• Example

  host1(config-if)#ipv6 nd prefix-advertisement 2002:1::/64 60000 45000 onlink autoconfig

• Use the no version of this command to remove any prefixes from the IPv6 routing advertisements.
• See ipv6 nd prefix-advertisement

ipv6 nd ra-interval

• Use to specify the interval, in seconds, between IPv6 router advertisement retransmissions on an interface.

• Example

  host1(config-if)#ipv6 nd ra-interval 500

• Use the no version of this command to restore the default interval,
  200 seconds.
• See ipv6 nd ra-interval

ipv6 nd ra-lifetime

• Use to specify the router lifetime value, in seconds, in IPv6 router advertisements on an interface. The router lifetime value is the amount of time the router is considered the default router on this interface.

• Example

  host1(config-if)#ipv6 nd ra-lifetime 900

• Use the no version of this command to restore the default lifetime,
  1800 seconds.
• See ipv6 nd ra-lifetime

ipv6 nd reachable-time

• Use to specify the amount of time that the E-series router can reach a remote IPv6 node after some reachability confirmation event has occurred.

• Example 1—Sets the reachable-time to 30,000 milliseconds

  host1(config-if)#ipv6 nd reachable-time 30000

• Example 2—Sets the reachable-time to 1 hour, 10 minutes, and 45 seconds

  host1(config-if)#ipv6 nd reachable-time 1 10 45

• Use the no version of this command to restore the default value (zero [0] milliseconds for router advertisements and 3,600,000 milliseconds [1 hour] for Neighbor Discovery activity of the E-series router).
• See ipv6 nd reachable-time

ipv6 nd suppress-ra

• Use to suppress IPv6 router advertisement transmissions on a local area network (Ethernet) interface.

• Example

  host1(config-if)#ipv6 nd suppress-ra

• Use the no version of this command to reenable the sending of IPv6 router advertisement transmissions on the LAN (Ethernet) interface
• See ipv6 nd suppress-ra

ipv6 nd suppress-ra-source-link-layer

• Use to suppress IPv6 router advertisement transmissions on a local area network (Ethernet) interface.

• Example

  host1(config-if)#ipv6 nd suppress-ra-source-link-layer

• Use the no version of this command to reenable the sending of IPv6 router advertisement transmissions on the LAN (Ethernet) interface.
• See ipv6 nd suppress-ra-source-link-layer
