IPv6 can work with static routing and dynamic routing protocols as well as IPv4. Configuration steps are similar, but there are a few differences too. RipNG, OSPFv3 and static routing configurations will be made for the figure below :
* First , IPv6 should be activated on each router via “ipv6 unicast-routing” command.
IPv6 CONFIGURATION : STATIC ROUTING
IPv6 static routing is activated via “ipv6 route” command. For the figure above, Router – 1 can ping Router -3 and Router -2 , static route will be written for establishing communication with Router – 4
R1(conf)#ipv6 route 2001:33AA::/64 2001:22AA::2 R2(conf)# ipv6 route :: /0 2001:11919 // Default route for Router 2 //
IPv6 routes can be verified via “show ipv6 route” command
IPv6 CONFIGURATION : OSPFv3 ROUTING
R1(config)#ipv6 unicast-routing R1(config)#int f0/0 R1(config-if)#ipv6 ospf 1 area 10 ex R1(config)#ipv6 router ospf1 R1(config)#router-id 0.0.0.1 ex R1(config)#int s0/0 R1(config-if)#ipv6 ospf 1 area 0
R2(config)#ipv6 unicast-routing R2(config)#int s0/0 R2(config-if)#ipv6 ospf 1 area 10 R2(config)#ipv6 router ospf 1 R2(config)#router-id 0.0.0.2
R3(config)#ipv6 unicast-routing R3(config)#int s0/0 R3(config-if)#ipv6 ospf 1 area 0 R3(config)#int f0/0 R3(config-if)#ipv6 ospf 1 area 20 R3(config)#ipv6 router ospf 1 R3(config)#router-id 0.0.0.3
R4(config)#int f0/0 R4(config-if)#ipv6 ospf 1 area 20 R4(config)#ipv6 router ospf 1 R4(config)#router-id 0.0.0.4
