Metric LocPrf Weight Path External EIGRP 6PE : 6PE technology relies on BGP , BGP 's Peer is the need to manually specify, it can be regarded as a semi-automatic tunneling technology. Le keyword is not written, then the default is greater than 24 less than 32 lab environment: Ipv6 unicast-routing interface Tunnel0 Route-map nat1 permit 10 match ip address 1 match interface serial0/0 Last update from 192.168.34.3 on Serial0/1, 00:09:32 ago Routing Descriptor Blocks: Ipv6 route ::/0 tunnel 0 Area Address(es): 49.0002 SNPA: *HDLC* Adjust the management distance of the routing protocol Interface Tunnel1 [Note] The process name is valid locally. If the two interfaces are enabled on the Router and RIPng is enabled with two different process names, the two processes are independent of each other. ! 00 In the routing table of R3 , there is only 1.1.1.0 route. Image Routing, then: 1 : RIP-1 ; Image Neighbor FE80::CE02:8FF:FED8:0 activate R2(config-router)# distribute-list 1 out The header forms an outer IPv4 packet, which is routed in the IPv4 network. As OR1 , OR2 empathy Now, on R3 , re-release the direct loopback route into BGP4+ The maximum hop count is still 15 hops The PC receives an RA message and will do a test: Image RA 134 ! Which exchange method will be used Neighbor 2001::1 next-hop-self Router ospf 1 Exit The configuration of R2 is as follows: R2(config)# access-list 1 deny 192.168.3.0 R2(config)# access-list 1 permit any R2(config)# router ospf 1 Tunnel source serial 0/0 tunnel destination 10.1.23.3 Static NAT-PT (one-way) Cancel the verification of IP [Note] If the interface is passive , but at the same time the network interface in the routing process, the interface will not attempt to send updates or establish neighbor relationships,ccna online, but the network segment where it is located will still be declared into the routing process. Level2 router factor Access-list 1 permit 172.16.10.0 Let's take the example of R1 . On R1 , the configuration might look like this: 0xFFFF Image The last command is to put the host of the IPv4 network 202.101.100.2 into the IPv6 network, so that the IPv6 only user has the access target. Otherwise, what destination address do you use the IPv6 only user to access the IPv4 only network? Access-list 2 permit 10.1.2.0 route-map cisco permit 10 Interface fast0/0 ipv6 enable R4.00-00 Establish BGP4+ neighbors and deliver IPv6 routes using IPv6 global unicast addresses . Neighbor 2002::2 remote-as 12 address-family ipv6 This is the problem, how to solve it? Very simple, on the OR2 , deploy PBR , as long as the server data from Netcom, all forced to OR1 , it is solved. Access-list 1 permit 1.1.1.0 Application example Interface fa1/0 Ipv6 enable Y Route-map OSPF3to1 permit 10 match tag 10 Router ospf 100 We see that the ICMPv6 message of this RS is the head of IPv6 , and the head of IPv6 is the head of IPv4 . Note the header of the outer IPv4 , the source is 1.1.1.1 , the purpose is 2.2.2.2 Prefix-delegation pool dhcppool lifetime 1800 600 Stateless autoconfiguration The new routing table is typically sent to neighboring routers on a regular basis, and the triggered update is sent immediately in response to changes in the routing table. Jul 20 2012 23:59 // Old prefix *> 2001:1111::1/128 Image !! Note that to support IPv6 unicast routing protocols, this switch must be turned on. Image 8 bits Isis circuit-type level-2-only Transmit limit accumulator 0x0 (0x0) IP MTU 1500 Epoch 0 ! Ip route 192.168.10.0 255.255.255.0 fast 0/0 Ipv6 unicast-routing interface Loopback0 In an IP network, Routing is a very, very basic concept. The basic function of the network is to make two in the network OK If you want to turn off ICMP redirects, you need to use no ip redirects on the interface . Ipv6 route 2002:CA65:C01::/48 Tunnel0 CISCO IPv6 Network Implementation Technology: CISCO self-study : Implementing Cisco IPv6 Networks (IPv6)No synchronization You can use the show cef interface command to check which load balancing mode is used. This command gives the CEF information configured on this interface . Router bgp 300 technical background [Test 1 ] Tunnel mode ipv6ip Image ! The implementation of diversified strategies at the level has been able to achieve very good path control effects, and it is a very scientific and highly recommended method to control the flow of data by controlling routing. In addition to this, there are many, such as: 4.4.4.4/32 Image Unassigned Router(config-if)# ipv6 rip xxx metric-offset ? UP Image At infinite Difficult case Router bgp 234 Image Address-family ipv4 Image In RIPv1 based on the increase The transition mechanism of V4 to V6 discussed above is basically the case where V4 and V6 coexist. So if there is a need for mutual access to the V4 single protocol and the V6 single protocol network? ! Ipv6 nat v4v6 source 202.101.100.2 2001:2::2 The IPv6 address used by the automatic IPv4 compatible tunneling mechanism is " IPv4- compatible IPv6 address". 0100 – 01FF Route-map features Pop tag Bgp router-id 2.2.2.2 Packet-based load balancing and process switching. Process exchange is for each packet , the router must perform routing table query and interface selection , and then query the data link information. Because each process that determines the routing of packets is independent of each other , all packets destined for the same target network are not forced to use the same interface. In order to open the process exchange function on the interface , you can use the command no ip route-cache under the interface . For IPv6 nothing needs to be done , because by default the feature is turned on.
