Address format: FF02:0:0:0:0:1:FFXX:XXXX , the specific correspondence is as follows: Configuration Example 3 (at a single routing protocols -OSPF ) Image 16/32 bit The tunnel server is a simplified model of the tunneling agent. The tunnel agent is integrated with the dual stack Router . In label/Out label Metric =0 IP protocol number 88 # x client host Async Async interface CE1 The IPv6 routing to put PE1 , PE1 created on IPv6 in the VRF , the Fa0 / 0 Kou into the VRF . PE1 learned through BGP TCP Interface On this topic, the individual feels that there is no need to study it. It does not make much sense for the research of class-based routing protocols. No matter the actual application or the LAB exam, it is no longer involved, and you are interested in making it yourself. Router-id 4.4.4.4 redistribute connected exit Certification Neighbor FE80::CE01:8FF:FED8:10 remote-as 12 1/256 Route tag: A tag that distinguishes between internal routing protocol routes and external routing protocol routes. R2#show ipv6 interface brief !! xxx is validtime , yyy is prefered time , this is absolute time The difference between set ip next-hop and set ip default next-hop is relatively simple, it is not resolved here. RIP re-releases the default route Establish BGP4+ neighbor relationships and pass IPv6 routes using IPv6 Linklocal addresses . Image 00 Vlan 20 interface fast0/1 !! Modify RIPng management distance, default 120 In fact, there are two main lifetimes of IPv6 addresses , one is Valid lifetime and the other is preferred lifetime . First in Ipv6 address 2001:45::5/64 router bgp 100 RFC1723 defines an acceptance control switch By using route tags in RIP , you can control the redistribution of related routes in other protocols. When republishing to other protocols, RIP routes simply compare the tokens assigned to them without comparing the entire route. Use 224.0.0.9 10.1.13.3 6to4.ipv6.microsoft.com and so on. The R position 1 indicates that this is a router. ::FFFF: 4.4.4.4 Two-way re-release of OSPF and RIP MD5 is certified between R2 and R3 . ! Configure static routes by using the associated outbound interface. Re-routing release ( Redistributing Routing Protocols ) Ipv6 route 2002:CA65:C01::/48 Tunnel0 !!

Mechanism introduction Image Address-family ipv6 neighbor 2001::1 activate System Id Type Interface IP Address State Holdtime Circuit Id Multilink Multilink-group interface For the next hop and route tag, see Volume I, page 189 . The configuration of R2 is added as follows: Redistribute connected redistribute ospf 1 Interface FastEthernet0/0 ipv6 enable Now we configure it on the ISATAP router. The IPv4 address assigned to the router is 2.2.2.2/24 , and a Bgp router-id 2.2.2.2 This is the ICMP redirect message sent by R1 to R3 . Note that the Gateway address field in the header is filled with the next hop IP that is closer to the destination than the destination . The example here is DHCPv6 , using Router as the DHCPserver Image The following are the addresses and ports that DHCPv6 might use: IP Metric =0 Router-id 2.2.2.2 Route redirection !! GW has no other configuration about routing Then do a simple test: Ipv6 access-list ipv6only-network permit 2001:1::/64 any By default , Cisco routers enable fast switching or optimal switching or cef switching instead of process Ivv nd other-config-flag Note ISATAP router configuration, wherein the key part of tunnel configuration, tunnel mode ipv6ip isatap ,ccna 200-125 dumps download, while attention Ip address 10.1.34.4 255.255.255.0 IPv6 routing PC1 configuration: (Update source verification failed), on the other hand, R2 will not receive the 1.1.1.0 route from R1 , and then pass the same interface, with 11.1.123.2 Ipv6 route ::/0 tunnel 0 Configuration example No ipv6 nd suppress-ra R1(config-router)#distribute-list 1 in ? // All interfaces Image Ipv6 nat The behavior of the router is hop-by-hop. Each router along the path to the destination network must have a route to the destination. 10.1.13.3 The first 8 bits of the highest address of the multicast address are fixed to all 1 FFXX :: /8 ! Image Destination address: The address of the host or network. Set ip next-hop { ip-address [...ip-address] | recursive ip-address } When ISP1 is down, and the interface of GW connected to ISP1 is DOWN , the data of PC accessing 100 network is switched to ISP2. lab environment As OSPF2 create a route in the static summary routes ( the Null0 ), and static routes redistributed into OSPF1 modified OSPF1 administrative distance, the OSPF1 priority than OSPF2 administrative distance There is a network environment in which two IPv4 networks are connected by a pure IPv6 provider, and then IPv4 routes have to be exchanged through BGP IPv6 peers. Because BGP4+ supports IPv4 and IPv6 protocol clusters, this is perfectly fine . The ISATAP router thus traverses the entire IPv4 network. length Ipv6 unicast-routing interface Loopback0 Metric =0 Router(config-router)# passive-interface default Router(config-router)# no passive-interface int- type int-num Redistribute bgp 234 Followed by ACL to match traffic. FastEthernet0/0 Note: If CDP- based detection and object tracking- based detection are applied, the latter is preferred. Test phenomenon: unable to ping . 1 command) only sends and receives v1 messages, v2 only sends and receives v2 messages by default . Age Reply to ISP1 , GW perceives through tracking , and the data is switched back to ISP1. Look further at this route: basic configuration (2) Declare the loop port 1.1.1.1224 When both the primary and secondary addresses exist, RIP will use both the primary and secondary addresses as the source to send routing updates. So R1 and R3 will learn the routing update of 2.2.2.0 . But R3 ca n't learn 1.1.1.0 , on the one hand, because R1 sends updates to R3 and is ignored by R3. Route summary issues to be aware of Exit-address-family (2033::3, FF04::1), 00:00:04/00:03:24, flags: ST 100 R3 's gateway is R1 , R1 itself has static route to 2.2.2.2 , and the next hop is R2 . Note that this is an MA network. All three interfaces are on the same network segment. This is critical. R3 will go to 2.2.2.2. When the data is dropped to its own gateway 192.168.123.1 , R1 finds that the next hop of the data is 123.2 on the same network segment as the local inbound interface after searching through the routing table , so he thinks that 123.
