Chapter 4 Configuring the Access Point for the First Time
Configuring IPv6
normal four-message exchange (solicit, advertise, request, reply). By default, the four-message
exchange is used. When the rapid-commit option is enabled by both client and server, the two-message
exchange is used.
Beginning in privileged EXEC mode, use these commands to enable the DHCPv6 client in an Access
Point:
–
ap# conf t
–
ap(config)# int bv1
–
ap(config)# ipv6 address dhcp rapid-commit(optional)
Autonomous AP supports both Dhcpv6 stateful and stateless addressing.
Stateful addressing
Stateful addressing uses a DHCP server. DHCP clients use stateful DHCPv6 addressing to obtain an IP
address.
Beginning in privileged EXEC mode, use this command to configure stateful addressing:
ap(config)# ipv6 address dhcp
Stateless addressing
Stateless addressing does not use a DHCP server to obtain IP addresses. The DHCP clients autoconfigure
their own IP addresses based on router advertisments.
Beginning in privileged EXEC mode, use this command to configure stateless addressing:
ap(config)# ipv6 address autoconfig
IPv6 Neighbor Discovery
The IPv6 neighbor discovery process uses ICMP messages and solicited-node multicast addresses to
determine the link-layer address of a neighbor on the same network.
Beginning in privileged EXEC mode, use these commands to configure IPv6 neighbor discovery:
Command Purpose
ipv6 nd ? Configures neighbor discovery protocol.
ipv6 nd ns-interval value Sets the interval between IPv6 neighbor solicitation retransmissions on
an interface.
ipv6 nd reachable-time value Sets the amount of time that a remote IPv6 node is reachable.
ipv6 nd dad attempts value Configures the number of consecutive neighbor solicitation messages
sent when duplicate address detection is performed on the unicast IPv6
addresses.
ipv6 nd dad time value Configures the interval between IPv6 neighbor solicit transmissions
for duplicate address detection.
ipv6 nd autoconfig default-router Configures a default route to the Neighbor Discovery-derived default
router.
ipv6 nd autoconfig prefix Configures router solicitation message to solicit a router advertisement
to eliminate any delay in waiting for the next periodic router
advertisement.
