Stateless NAT46 static route injection configuration example
Figure 16 shows a typical IPv4-only client to IPv6 resource topology configured with router
adjacency relationships on both the IPv4 and IPv6 sides of the ServerIron ADX (NAT46 gateway).
FIGURE 16 NAT46 route injection example
The following configuration example shows the steps required to configure a stateless NAT46
gateway for route injection into OSPF.
1. An IPv6 address is configured: VLAN 1 is configured with VE 7, which has an IPv6 address
(2001:db8:8000::1).
ServerIron ADX(config)# vlan 1
ServerIron ADX(config-vlan-1)# interface ethernet 1 to 2
ServerIron ADX(config-vlan-1)# interface ve 7
ServerIron ADX(config-vlan-1)# exit
ServerIron ADX(config)# interface ve 7
ServerIron ADX(config-vif-7)# ipv6 address 2001:db8:8000::1
ServerIron ADX(config-vif-7)# exit
2. OSPF and OSPFv6 are configured for static route redistribution. The IPv4 side is configured as
OSPF Area 0 and the IPv6 side is configured as OSPF Area 1.
ServerIron ADX(config)# router ospf
ServerIron ADX(config-ospf-router)# redistribute static
ServerIron ADX(config-ospf-router)# area 0
ServerIron ADX(config-ospf-router)# exit
ServerIron ADX(config)# ipv6 router ospf
ServerIron ADX(config-ospf6-router)# redistribute static
ServerIron ADX(config-ospf6-router)# area 1
ServerIron ADX(config-ospf6-router)# exit
3. The NAT46 IPv4 prefix is configured with static route injection.
ServerIron ADX(config)# nat64 ipv4-prefix 100.1.1.0/24 inject-static-route
4. The NAT46 IPv6 prefix is configured with static route injection.
ServerIron ADX(config)# nat64 ipv6-prefix 2001:db8:8000::0/96
