At the beginning of the year 2011, we decided to apply the IPv6 configuration to our data center (VeriTeknik<\/a>) and requested our IPv6 block from RIPE. RIRs give out \/32 blocks to LIRs at the first assignment. This article describes basic Cisco IPv6 configuration.<\/p>\n

The Preparation Steps<\/h3>\n
    \n
  1. Request your IPv6 Addresses from your RIR or LIR<\/li>\n
  2. Add IPv6 Route to your AS number in LIR Portal<\/li>\n
  3. Get your IPv6 VLAN IP from your Upstream Provider<\/li>\n
  4. Configure your router<\/li>\n<\/ol>\n

    Configuring Cisco Routers for IPv6<\/h3>\n

    Before you start applying IPv6 on your routers make sure that you backup your current configuration.<\/p>\n

    First of all, make a table of your arguments such as your IP addresses, AS numbers etc like below, we put some values for you to easily analyze the configuration:<\/p>\n\n\n\n\n\n\n\n
    Your AS Number<\/strong><\/td>\nAS65535<\/td>\n<\/tr>\n
    Remote As Number<\/strong><\/td>\nAS1000<\/td>\n<\/tr>\n
    VLAN IP Your Side (Given by Telco op)<\/strong><\/td>\n2A01:358:4500:2::2\/64<\/td>\n<\/tr>\n
    VLAN IP remote\u00a0Side (Telco Side)<\/strong><\/td>\n2A01:358:4500:2::1<\/td>\n<\/tr>\n
    Your IPv6 Addresses to Announce<\/strong><\/td>\n2B00:7300::\/32<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

    Enable IPv6 & IPv6 CEF on your Cisco router:<\/strong><\/p>\n

    ipv6 unicast-routing\nipv6 cef\n!<\/pre>\n
    Set your IPv6 address to the interface facing telco:<\/strong><\/p>\n
    Don’t delete your IPv4 configuration or other necessary codes, just add<\/p>\n
    interface GigabitEthernet0\/0\ndescription $ETH-WAN$\nipv6 address 2A01:358:4500:2::2\/64\nipv6 enable\nipv6 virtual-reassembly\n..\n..\n!<\/pre>\n
    Switch to BGP configuration by typing “router bgp 65535”<\/strong><\/p>\n
    add:<\/p>\n
    router bgp 65535\n.\n.\nneighbor 2A01:358:4500:2::1 remote-as 1000\n!<\/pre>\n
    type exit and type address-family ipv6<\/strong> to enter IPv6 configuration<\/p>\n
    to announce your prefixes type:<\/p>\n
    address-family ipv6\nneighbor 2A01:358:4500:2::1 activate\ndistance bgp 200 200 200\nnetwork 2B00:7300::\/32\nnetwork 2B00:7300:100::\/48\nredistribute connected\nredistribute static\nno synchronization\nexit-address-family\n!<\/pre>\n
    Type exit one more and you need to add routes for your IPv6 addresses,<\/p>\n
    ipv6 route 2B00:7300::\/32 Null0 254<\/pre>\n
    This is the basic IPv6 configuration for Cisco routers, now you should be able to communicate with IPv6 enabled hosts. To test your configuration you may assign IPv6 to one of your VLANs, an example given below:<\/p>\n
    interface GigabitEthernet0\/1.201\ndescription LOCAL\nencapsulation dot1Q 201\n.\n.\nipv6 address 2B00:7300:100::1\/48\n!<\/pre>\n","protected":false},"excerpt":{"rendered":"
