E.g: The tunnel is automatically enabled between isolated hosts on the IPv4 network to implement IPv6 data transmission in the tunnel. Source and destination IPv6 addresses are lower 32 10.1.13.3 ! Reachable, receive confirmation, do not continue to send package confirmation Default route delivery If it is RIP , the network specified by the ip default-network command does not need to be displayed to announce RIP , and once the default gateway is specified, RIP Image Ip route 0.0.0.0 0.0.0.0 serial s0/2 0x7768 When R2 is configured with no validate-update-source , R2 will not verify the RIP update message source, so R2 will accept R1. None R1 goes to ping R4 and can ping . Ip address 10.1.23.2 255.255.255.0 Weight Ipv6 unicast-routing Ipv6 address 2004::4/64 Ipv6 address 2000:12::2/64 ipv6 ospf network point-to-point ipv6 ospf 1 area 0 The BGP4+ configuration of R1 is as follows: End deny any Image Exit-address-family PC is the ISATAP host, it is a dual-stack PC , here we are using a win7 system computer for testing. The IP address of the computer network card is 1.1.1.1/24 , the gateway is 1.1.1.254 , and the gateway is the interface vlan10 of SW1 . Message introduction [Interrupt] In the IPv4 header added by R1 , the protocol field is used to indicate that the upper layer encapsulates the IPv6 packet, and the protocol field value is 41 : Bgp router-id 3.3.3.3 BGP table version is 2, local router ID is 2.2.2.2 Transition from the old routing protocol to the new routing protocol At the same time, the tunnel proxy automatically applies the remote configuration of the configured tunnel on a dual-stack router connected to the IPv6 network. Once the configuration is applied on the dual-stack host and the dual-stack router,ccna 200-125 braindump, the tunnel is correctly established. 2034::4 V6 can actively access V4 (using V4 address pool) ! Router(config)# ipv6 router rip name RIP-1 compatibility RIPv2 sends updates in the form of broadcasts, enabling V1 to receive Avoid routing loops with triggered updates Address resolution ( instead of ARP protocol, using ICMP to complete address resolution ) Y ! Image Ipv6 access-list ipv6only-network permit 2001:1::/64 any ipv6 nat prefix 2001:2::/96 This is a very typical scenario. GS_SW is an aggregation layer switch that runs OSPF with the core switch . The GS_SW needs to advertise the network segment corresponding to the VLAN to be hanged , so that the core switch can learn the relevant routes. Then, once GS_SW announces the network segment corresponding to these VLANs in the OSPF process , the corresponding SVI interface will flood the OSPF HELLO message to the VLAN , and these messages are actually redundant.
