NET entity address 16 bits Ipv6 enable interface Serial0/1 Ipv6 route ::/0 tunnel 0 Interface FastEthernet1/0 ipv6 ospf 1 area 0 URL representation of the IPv6 address Unassigned Ip cef The configuration of PE1 is as follows: Subnet router anycast address: UNICAST_PREFIX : 0:0:0:0 ICMPv6 is one of the basic protocols of IPv6 . Protocol number 58 , which is in the "Next Header" field of the IPv6 header. The session between Source and Destination is established. Turn on router advertisement at the same time (default is off) ::FFFF: 4.4.4.4 Required IPv6 address Pointer to the target: The pointer does not point to the router's direct connection to the destination network or to another router address in the directly connected network , or to the local interface of the link. A router that is closer to the target network is called a next hop router. Ipv6 address 2002:84d6:010a:0001:/64 eui-64 !! This is the gateway for the IPv6 site intranet Image !! The prefix of this IPv6 address will be advertised to the ISATAP host. R1 and R2 are dual-stack routers. The configuration of R1 is as follows ( the configuration of interface IP is omitted ): Interface fast1/0 Prefix announcement Image Image No frame-relay inverse-arp ipv6 enable METRIC Path System Id Type Interface IP Address State Holdtime Circuit Id Update message: contains the entire routing table, updated periodically RIPv2 note: LSP Holdtime Ip unnumbered fastEthernet 0/0 ipv6 enable After the PC , the PC regards the Router as a gateway, this lifetime Configuration example FE80::/10 Thus, A initiates access connection to B , or B initiates access to the A can be. Ipv6 local pool dhcppool 2001::/64 64 Ipv6 dhcp server DHCP-pool !! Enable ipv6 DHCP on the interface and call the pool CDMA-Ix CDMA Ix interface 10.1.23.3 R3.00-00 In IPv6 BGP transmitted between peers IPv4 routes !! Match the exit of the packet 2001:45::/64 [Start fast exchange] 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 . CISCO IOS does not yet support tunnel servers. length 110 1/16 Reply to ISP1 , GW perceives through tracking , and the data is switched back to ISP1. Each routing table entry must include at least the following three items: NAT (Network Address Translation) 90 If you want to turn off ICMP redirects, you need to use no ip redirects on the interface . PE1 and PE2 activated between MPBGP neighbor relations, to pass VPNv6 ready prefix Image Router isis RFC2766 , RFC2765 . NAT-PT (Network Address Translation - Protocol Translation) is an address translation technique that translates IPv6 addresses into IPv4 addresses and vice versa. NAT-PT is based on the stateless IP/ICMP converter ( SIIT ) algorithm defined in RFC2766 . SIIT algorithm translation OSPFv3 configuration Can I handle AS-external-lsa , usually ASBR? Interface R1 R2 Ipv6 address 2001:12::2/64 ipv6 ospf 1 area 0 You can use the show cef interface command to check which load balancing mode is used. This command gives the CEF information configured on this interface . BVI Bridge-Group Virtual Interface E Ip cef Interface loopback 0 Image Ipv6 nd prefix 2001:0002::/64 10.1.12.2 Ip route 192.168.10.0 255.255.255.0 192.168.1.1 Set ip next-hop ip1 ip2 ip3 , this knowledge point is no problem,ccna mock exam, right? After the match lives, the packet is first sent to the first next-hop ip address . If the direct connection associated with the ip address is DOWN , then the next next-hop ip address is switched . Multiple next-hop . However, if the directly connected next-hop (the peer router or its interface) hangs itself, and the local direct interface is not perceived (such as the middle switch ), it cannot be automatically switched, and the router will still put the data in the brain. Throw it to this next-hop .
