IPv6 network, here we use loopback simulation: 2001:8888::8/64 for subsequent testing. 7 Ip address 10.1.34.4 255.255.255.0 Destination Address ! Define multiple serial numbers under route-map . The serial number has a priority order when performing matching actions. 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 Message name R1 and R2 are dual-stack routers that connect to both IPv6 and IPv4 networks. The PC receives an RA message and will do a test: The configured static network path is redistributed into OSPF . In this way, when the intranet user needs to access the Netcom resources,ccna dumps free download, because of the details of the network access, go to OR1 . To access other resources, take the default route to OR2 . Ipv6 unicast-routing As OR1 , OR2 empathy Ip address 202.101.23.3 255.255.255.0 After this command is configured, the prefix information on the interface cannot be used for stateless autoconfiguration by the host on the link. The host must use stateful autoconfiguration such as DHCPv6 to obtain the address. By default, this command is not configured, that is, the managed-config-flag is 0 , which means that the host can obtain the address through a stateless configuration. NS 135 RIPng for IPv6 FF01::1 node local range all node multicast address Therefore, in the case of dual stack, when the PC DNS is parsed, the AAAA record is generally requested first . The result is unreasonable, because the message exceeds the MTU of the R2 Fa1/0 port when it is passed to R2 , so R2 sends back an ICMPv6 message with TYPE=2 ( packet too big ) to R1 . In this back to R1 in the ICMPv6 message includes the allowed the MTU = 1400 , to inform the L1 Se0/0 FastEthernet FastEthernet IEEE 802.3 Image 00 The intranet has a network segment, 192.168.10.0/24 , which is the server network segment. Static NAT mapping is deployed on OR1 , and the specific server is mapped to the exit of OR1 . In this way, Netcom users can access the external network. Access to these server resources. But the problem is that the external network users of the telecom cannot access these server resources through the mapped external network address.
