The configuration of CE2 is as follows: When the link between R1 and R3 fails, the same network will still have problems. Because R2 re-releases the locally configured static summary route into the Roo also received the request, and the request it received from the network segment 172.16.20.0 , and the table found that the network that the route to the host Milne is located ( 172.16.21.0 ) is different from the network that received the arp request packet. And the interface opens the arp proxy, so reply to its own interface mac. Routing, accept updates. FF02::1:FFF0:10 Difficult case Interface serial0/0 Interface Tunnel0 ipv6 enable Look at R1 : Scop is used to limit the range of multicast data streams sent over the network. A few notes: Here to add a sentence, since attention to traffic, we must pay attention to the round trip of traffic, in general, we want 1.1.1.0 access 3.3.3.0 traffic to go ADC , then round-trip traffic generally requires a consistent path. That 3.3.3.0 to 1.1.1.0 data to a CDA , so to further D on the update to the C of 1.1.1.0 route of metric plus 1 jump. Image Router redirection Routing strategy 100 Bgp router-id 4.4.4.4 OSPF Mpls ldp router-id Loopback0 mpls label range 300 399 Image 0 , regarded as infinity No auto-summary no synchronization First, the Source sends an IPv6 packet to the target node with 1500 bytes as the MTU. V6 Next, let's take a look at the detailed process of packet interaction: FE80::CE02:8FF:FED8:0: martian next hop R2# No bgp default ipv4-unicast neighbor 4.4.4.4 remote-as 234 ! ! !! is a pool reserved for NAT-PT Also, when R2 hangs,ccna dumps 200-125 pdf free download, the entry of 172.16.2.0/24 is invalid, and the data destined for the 2.0 subnet is matching 172.16.0.0/16. 1/8 Interface FastEthernet0/1 ............ 27 Neighbor FE80::CE02:8FF:FED8:0 activate Image Interface Loopback0 Header format Interface Tunnel0 ipv6 enable The basic IPv6 header 40 th . 8 bit 'bit , i.e., 40 bytes long, a total . 8 fields. Note that if you use a virtual machine configuration, you must manually configure the linklocal address on the serial interface. Ip sla monitor schedule 2 life forever start-time now Access-list 1 permit 100.1.1.0 !! Modify RIPng management distance, default 120 Network 192.168.23.2 0.0.0.0 area 0 distribute-list route-map test in Now, we have to go through the calculations to get a summary of the segments that are just "inclusive". 3 : MD5 verification. !! These three representative routing re-release models. 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. Ipv6 address 2001::FFFE/64 ipv6 nd other-config-flag ipv6 nd managed-config-flag Routing Protocols Image 0800 – 0FFF This global configuration command enables PBR to take effect on locally originated traffic. Image Configuration command After the trigger update is enabled, the routers at both ends of the link no longer send routing updates periodically. Of course, another problem arises. If the route in the routing table expires, it will hang, so it is necessary to trigger the update. It must be configured on both interfaces of the link, so that the routing update will be marked permanent for permanent. 10 Www.6bone.net Interface FastEthernet1/0 ipv6 enable If no conflict is detected after 1S , A will send a non-solicited advertisement (an NA message), announcing that I will officially use this IPv6 address. None 10.1.31.0/24 This subnet has been successfully updated " 10.1.31.0 " because it is the same as the main source of the R1 update source interface . Address-family ipv6 Interface Loopback0 In the Probe state, every unicast NS is sent every RetransTime ( r default 1S ) , and MAX_Unicast_Solicit is sent before waiting for RetransTimer . Passing the value of Tag Ipv6 local pool dhcppool 2001::/64 64 If the packets of the same data stream are sent in different paths, the IP packets may need to be re-queued when they reach the destination. This may reduce the forwarding performance of traffic such as VoIP , or if the packets arrive out of order, the quality of service will be degraded, packets may be discarded, and delay jitter will be added. The destination IP address of the route , which can be the address of the natural network segment or the subnet address or Image The standard ACL active part and destination part use the source matching route prefix and use the destination part matching route mask. !! Construct an Ipv6 address using the EUI64 address; 29 NS 135 In the above figure, R1 and R3 will update routes 1.1.1.0 and 11.11.11.0 to R2 . Of course, by default, R2 is definitely the preferred EIGRP. !! ipv6 routing, all traffic to the IPv6 network is thrown into the tunnel !! Re-release direct connection Ipv6 address 2002::2/128 Because of this mapping, R2 will B sent over the packet destination address of 202.101.100.100 replaced with 2001: 1 :: 1 , while the B source address is an IPv4 address, supposed to do? Remember that we configured the prefix reserved by NAT-PT ? I.e. 2001: 2 :: / 96 this stuff, R2 to B 's IPv4 mapped address prefix to form a temporary IPv6 address: 2001: 2: CA65 : 6402 , while generating a new local map entry: 2001:2::CA65:6402 maps to 202.101.100.1 as shown above.
