The polymerizable global unicast address ( Aggregatable Global unicast address ) So 6to4 tunnel is done automatically find and set up, without having to manually configure the tunnel 's Where do you want , compared to the tunnel configuration, scalability is higher. FF02::1:FFF0:10 Default route ! ::FFFF: 4.4.4.4 1/32 Route-map test permit 10 Ipv6 nat prefix 2001:2::/96 Image IP routing troubleshooting Note that the 6to4 tunneling technology does not support dynamic routing protocols. 2001:45::/64 1 : Request message, requesting all or part of the routing information from the neighbor; 00 Access-list 2 permit 192.168.3.0 Image For the next hop and route tag, see Volume I, page 189 . 192.168.1.0 declares that it has entered RIP , and R3 and R4 can learn this route and load it into its own global routing table. Then if we are at Network 3.3.3.0 mask 255.255.255.0 0xFFFF Generally, it is 60-240 seconds longer than the invalid timer . If this time also expires, the routing entry is completely deleted. Cisco default 60s (note than invalidtimer multi- 60s ), RFC default 120s Mpls ldp router-id Loopback0 mpls label range 200 299 MC When both the primary and secondary addresses are present, the RIPV1 router will use the mask of the secondary address of the interface that receives the route update packet locally (this has been verified in the above experiment). OSPFv3 the RouterID or 32bits , if not on the router IPv4 address, in OSPFv3 manually specify the required process Then the received route becomes 10.1.20.0/24 and the mask is correct . Ipv6 address 2012::FFFF/64 Router ospf 1 Fa0/0 [Test 2 ] Interface FastEthernet1/0 Address structure Ipv6 address 2001:0002::FFFF/64 ipv6 enable Image Router request ( RS ) IPv6 address : 2001: 1111 :: 200: 5efe : 1.1.1.1 Focus on the configuration of GW : Router-id 4.4.4.4 The default is 6 update cycles, which is 180s . The route entry tag when an entry with a larger hop count is received FastEthernet1/0 Network 3.3.3.3 0.0.0.0 area 0 Port-channel Ethernet Channel of interfaces Interface tunnel1 Ipv6 enable TCP 1400 ! We found that on R1 , the route is not best , it is very simple, because NH is unreachable. The solution is simple, do next-hop-self on R2 on R3 FlowLabel : Flow Label, for QoS ! Aggregate Router isis Image SW1 creates two VLANs : VLANs 10 and 20 , which correspond to PCs and ISATAP routers. The IP address of the SVI port of VLAN20 is The IS-IS domain is based on a two-layer structure, Level1 and Level2 , and the concepts of L1-router , L2-router, and L1L2-router , and IPv4 IS-IS . *> 2003::3/128 The 64bits interface ID , and FE80 :: / 10 constitute a PC 's Linklocal address: fe80 :: 200: 5EFE: 1.1.1.1 At the same time, PC will ISATAP router Linklocal address fe80 :: 5efe: 2.2.2.2 set as the default gateway OUT direction Configuration command Router ospf1 Track 1 rtr 1 reachability Image GRE tunnel configuration By default, the CISCO router enables DAD , and the number of NS messages sent on the local link is 1 before determining the uniqueness of an address . Use the above command to modify the number of NS messages. A 0 turns off the DAD . Neighbor 4.4.4.4 update-source Loopback0 ISATAP router establishes a tunnel and get IPv6 addresses, but also to be able to ping through 20001: 8888 :: 8 B removes the IPv4 header of the packet , obtains the original IPv6 data,ccna exam latest dumps, and forwards it to PC2 . Address format: FF02:0:0:0:0:1:FFXX:XXXX , the specific correspondence is as follows: Then, R3 deploys the two-way re-release, so the process 2 route is injected into process 1 , then the route of the A network segment will be injected back into process 1 , so that the priority of O is greater than OE , so R1 and R2 directly ignore this. Strip routing. Will not cause other effects. Port number 521 Image Configuration command Ipv6 nd ra-lifetime Match interface s 0/0 Vif PGM Multicast Host interface Destination Address (Route Prefix): This is the destination network number associated with the route entry. A complete route prefix consists of: network number + prefix length Mpls ip Image Preferred lifetime ( of Preferred Lifetime ) Ipv6 unicast-routing ipv6 cef Image Ipv6 nat Unassigned Image Configuring the sample EIGRP environment A specified 32bits of Router-ID 0xF895 ( Routing Table ) , the routing table is loaded with routing entries ( routes ) learned by the router . The routing entries are composed of routing prefixes (destinations associated with routes), routing information sources, outgoing interfaces, or next hop IPs . The router obtains routing entries and maintains its own routing table in a static or dynamic manner. ! It can be seen from the CEF table that when PE1 receives the traffic from CE1 to CE2 at 2001:5555::5 , the label is compressed by two layers, and the outer layer is 301 , which is distributed by the P router, and the inner layer is 403 . PE1 is distributed. Image Prefix re-addressing allows a smooth transition from the previous network to the new prefix, and intra-site nodes use stateless autoconfiguration (or other re-addressing methods, but not as transparent as stateless auto-configuration methods), which allows the prefix to be re-edited The address process is transparent to the nodes in the site, that is, the nodes in the station are completely "uninformed" or "non-aware", and the deployed actions are completed on the router, and the switching process is smooth.
