Chapter 5. IBM System Networking RackSwitch implementation 195
2. Configure the router nodes interfaces (Example 5-43).
Run ipv6 address <IPv6 address> <prefix length> [anycast|enable] to configure a
primary unicast IPv6 address on an interface.
Run ipv6 secaddr6 address <IPv6 address> <prefix length> [anycast] to assign a
secondary anycast address to an interface.
Example 5-43 Router node interface configuration
ACC-1#configure terminal
Enter configuration commands, one per line. End with Ctrl/Z.
ACC-1(config)#interface ip 106
ACC-1(config-ip-if)#ipv6 address fc10::2 64
ACC-1(config-ip-if)#ipv6 secaddr6 address fc10::1 64 anycast
ACC-1(config-ip-if)#vlan 10
ACC-1(config-ip-if)#enable
ACC-1(config-ip-if)#^Z
ACC-1#
We use static IPv6 address and default gateway assignment for the hosts in our
architecture, but for completeness, we provide the basic Router Advertisements
configuration. For detailed information, see 5.5, “More information” on page 238.
To enable Router Advertisements for the specified interface, run the ipv6 nd related
commands.
Run [no] ipv6 nd suppress-ra to enable or disable IPv6 Router Advertisements on the
interface. The default setting is disabled (suppress Router Advertisements), so use the no
parameter to activate them.
IPv6 interfaces and VLAN: The IPv6 interfaces are mapped to the same VLAN as
their IPv4 pairs:
AGG-1#
interface ip 101
ip address 10.0.101.2 255.255.255.252
vlan 101
enable
exit
interface ip 111
ipv6 address fc11:0:0:0:0:0:0:2 64
vlan 101
enable
ip6host
exit
AGG-1#
Aggregation and access switches: Configure all the interfaces between aggregation
and access switches as router nodes, using the input information from Chapter 3,
“Reference architectures” on page 107.
