Before we start… 3 Things I Now Know: 1)2)3) 2 Things that were interesting: 1)2) 1 Question I still have: 1) Please get out a sheet of paper and write down the following. Label your paper IPv6 321 Reading Review.

Peer/Group Interaction… 1. Pair up with the student next to you and share your papers. 2. Work with your partner to isolate the two most significant facts to share with the class. 3. Work with your partner to isolate the most significant question to share with the class while I write those questions on the board. 4. Today’s challenge: write these questions on your paper, search for answers to these questions before our next class, and be ready to share your answers during the next class period.

Using IPv6 in the Network You are the Network Administrator. You have 3 routers in your organization. Your job is to: Migrate your IPv4 networks at each of your 2 sites to IPv6. Both sites connect to the Internet via Frame Relay links to your ISP’s Edge router.

Planning Does my equipment support IPv6? Does my equipment support IPv6? If not, can it be upgraded? If not, can it be upgraded? If so, how do I upgrade? If so, how do I upgrade? Use the Cisco Feature Navigator to find an image that supports IPv6 Use the Cisco Feature Navigator to find an image that supports IPv6 Download the new image Download the new image Upgrade the IOS on the routers with the new image Upgrade the IOS on the routers with the new image

Commands to Know Ipv6 address ipv6-prefix/prefix-length eui-64 BREAK IT DOWN… Ipv6-prefix = the ipV6 network Prefix-length = the length of the IPv6 prefix eui-64 = specifies interface ID in the low order 64 bits (low order from right to left)

EUI-64 EUI-64 uses the 48 bit MAC address of an interface. Recall that the MAC address = 24 bit OUI (Organizational Unique Identifer) + 24 bit Local Portion EUI-64 = 24 bit OUI bit Local

Commands to Know… ipv6 enable – enables IPv6 processing on an interface that does not have an explicit IPv6 address. ipv6 rip word default-information {only | originate} - originates a default IPv6 route into the RIP BREAK IT DOWN… word = name of the IPv6 RIP routing process only = advertises the IPv6 default route (::/0) only. originate = advertises the IPv6 default route (::/0). advertisement of other routes unaffected. RIPng is RIP next generation. IPv6 compatible version of RIP. Similar to RIPv2 for IPv4.

Commands to Know… ipv6 rip word enable – enables IPv6 RIP routing process on an interface. ipv6 router rip word – configures an IPv6 RIP routing process. “word” is a word that describes the routing process. ipv6 unicast-routing – enables forwarding of IPv6 unicast packets.

Commands to Know… ping ipv6 destination – test connectivity. “destination” is the destination name or address of the system to ping. show ipv6 interface [brief] [interface-type interface-number] – displays the usability status of IPv6 interfaces. BREAK IT DOWN… brief = summary of IPv6 status and configuration interface-type = displays information only about this interface type interface-number = displays information only about this interface #

Commands to Know… show ipv6 neighbors [interface-type interface-number | ipv6-address] – displays IPv6 neighbor discovery cache information show ipv6 route [ipv6-address | ipv6-prefix/prefix-length | protocol – displays current contents of IPv6 routing table

Lab Scenario Due to the growth and availability of IPv6 Internet sites, management has tasked you with upgrading the routers in your organization to IPv6. Due to the growth and availability of IPv6 Internet sites, management has tasked you with upgrading the routers in your organization to IPv6. You will: You will: Find and install and IOS image that supports IPv6 Find and install and IOS image that supports IPv6 Enable IPv6 unicast routing Enable IPv6 unicast routing Enable IPv6 on each participating interface Enable IPv6 on each participating interface Assign appropriate IPv6 addresses Assign appropriate IPv6 addresses Configure RIPng to route traffic Configure RIPng to route traffic
