Image Image Interface Serial0/0 2001:45::/64 Here are a few concepts to make clear: UDP A few notes: At this point, the initial configuration has been completed. Prefix list is much more controllable than access list, supports incremental modification, and is more flexible ! So match interface is a match with the outbound interface attribute, and this We see that the PC first generates an interface ID of 64 bits according to its locally configured IPv4 address: 1.1.1.1 : !! Restart after installation, default to open stateless automatic access address REACH In the in direction, the distribution list can only filter the route when the LSA is received locally. When the route is generated, the router's own routing table that implements the distribution list will be affected by the distribution list (but the local LSDB still has the LSA ), and router will still LSADB in Ip default-network 172.16.3.0 Image Image Not used (set to all 0s ) 0x0000000E [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. RIP version number: Ipv6 router isis C 192.168.23.0/24 is directly connected, Serial0/1 The node has two protocol stacks, IPv4 and IPv6. The certificate contains the password information when it is verified using plain text. 6to4.ipv6.microsoft.com and so on. 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 Interface tunnel 0 The tunnel server is a simplified model of the tunneling agent. The tunnel agent is integrated with the dual stack Router . Field name In the above example, the phenomenon we mentioned, R4 will know the route from OSPF and RIP to 192.168.1.0/24 , and finally R4 will choose OSPF route. This is a phenomenon we don't want to see in this environment, because it creates a sub-optimal path. The AD values ​​for several common routing protocols are listed below: 2001:1::1 ! Router(config-if)#ipv6 adress 2002::/64 eui-64 !! Also configured with an IPv6 address and populated with EUI-64 10.1.13.3 In fact, there are two main lifetimes of IPv6 addresses , one is Valid lifetime and the other is preferred lifetime . First in 32 bits The node has two protocol stacks, IPv4 and IPv6. In the example, the static route associated with the next hop does not have this attribute, so it is not matched. IS-IS Level-1 LSP R4.00-00 OSPF 's neighbor command is not the same as EIGRP . After testing, in the Ethernet environment, directly refer to the neighbor , and still send multicast hello. ! R1 and R3 respectively apply for the public network Ipv4 address and configure a dynamic 6to4 tunnel. In R1 , for example, arranged Tunnel 0 , assign an IPv6 address ( 6to4 address), this address is R1 is V4 external network address corresponding to the IPv6 6to4 address,ccna-security-dumps.blogspot . c o m, i.e. 202.101.12.1 corresponding to Exit-address-family R3 The first 8 bits of the route must match the first 8 bits of 172.0.0.0 , the other bits do not care, and the mask must be /8 , /9 , /10 , ..., /24 Address-family ipv6 PC1#sh ipv int IP policy routing is disabled Image Redistribute static subnets Image !

Each router along the path to the destination network must have a route to the destination. 0100 – 01FF Ipv6 router ospf 1 router-id 1.1.1.1 The above-mentioned IPv4 address is IPv6 public address isolated site, in the IPv6 / IPv4 border router ( 6to4 configure the router) V4 addresses may be directly 6to4 router interface connected to the public network the IP , may be a 6to4 router Loopback Interface the IP , the IP is also the 6to4 tunnel of source or Where do you want . Y 3 : local subnet range; Image After the command is configured on the interface, the routing table is not updated periodically in this direction, but the update is triggered. The routing table update will be minimal , including only the initial exchange information of the routing table and the updated information when the routing table changes. This command is only valid on the serial link and must be configured at both ends of the link to produce an effect.
