134 For example, to fetch the 192.168.1.0/24 route, access-list 100 permit ip 192.168.1.0 0.0.0.0 255.255.255.0 Maximum route entry Route-map PBR permit 20 match ip address 2 If the static route configured by the outbound interface is configured, the router considers the destination network segment as a local direct connection . Therefore , when the RIP is in the network , it will be announced. The identifier of the authentication item indicates that the entire routing packet needs to be verified. Here , the "high-order 32bits reserved for ISATAP " in the 64-bit interface identifier is described on Wikipedia: " The link-local address is determined by concatenating fe80:0000:0000:0000: 0200:5efe: for global unique Router(config)# router isis [ tag] Ipv6 address 2001:0001::FFFF/64 ipv6 rip RIPprocess enable Route tag: A tag that distinguishes between internal routing protocol routes and external routing protocol routes. Different OSPF between two-point two-way process re-release, can also use a static summary route re-issued, respectively, in two ASBR create different static routes summary above, re-publish static summary routes in the corresponding processes. IP prefix lookup IPv4 mtrie 8-8-8-8 optimized Input fast flags 0x0, Output fast flags 0x0 ifindex 3(3) (2) Declare the loop port 1.1.1.1224 Authentication Type 00 Tunnel mode ipv6ip The above command is to create an address pool for v6tov4 . This address pool is of course an IPv4 address pool. When an IPv6 only user, such as A, wants to access an IPv4 only network, it takes an idle IPv4 address from the pool. . Index 1/1/1, retransmission queue length 0, number of retransmission 0 First 0x0(0)/0x0(0)/0x0(0) Next 0x0(0)/0x0(0)/0x0(0) Case: Implementing intranet export data diversion through PBR Configure on R2 as follows: Overview Ipv6 ospf 100 area 0 interface serial0/1 ICMPv6 ( RFC2463 ) Y 2.2.2.2/32, version 55, epoch 0, per-destination sharing 0 packets, 0 bytes Neighbor 2002::2 remote-as 12 address-family ipv6 Router bgp 234 R* 0.0.0.0/0 [120/1] via 192.168.12.1, 00:00:03, Serial0/0 R2 the original IPv4 header packet replacing IPv6 header, and then transferred to A . This RS message sent by the ISATAP host will be routed in the IPv4 network and eventually forwarded to the ISATAP router. This will cause the router to immediately respond with an RA : Show ip cef Application prefix list Match ip address 1 Initially, R3 can learn three loopback routes from R1 and 192.168.12.0/24 routes. Now we don't want R3 to learn the route to 192.168.3.0/24 , then we can configure it on R2 as follows: Show ipv6 neighbor Straight connector The O position 1 indicates whether the entry in the NA message overwrites the existing one, and the neighbor who receives the message overwrites the existing entry. Ipv6 nat prefix 2001:2::/96 v4-mapped v4map RIP-2 Only Complete the construction of the environment and the basic configuration of the device to ensure the interconnection of the entire network. ::FFFF:4.4.4.4 (metric 3) from 4.4.4.4 (4.4.4.4) Mechanism introduction 2001:1111::1/128 Exit-address-family [Results] There is only 1.1.1.0 route in the routing table on R2 . R1 and R2 are dual-stack routers that connect to both IPv6 and IPv4 networks. ! O - OSPF intra, OI - OSPF inter, OE1 - OSPF ext 1, OE2 - OSPF ext 2 ON1 - OSPF NSSA ext 1, ON2 - OSPF NSSA ext 2 RIP-2 RIPv2 uses multicast update Provide a better next hop address. If it is 0.0.0.0 , it means the way to publish this route. 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 Ip route 0.0.0.0 0.0.0.0 192.168.23.3 0100 – 01FF Stateless configuration,ccna test prep, and an NDP mechanism when the node boots . The uniqueness of the IPv6 unicast address used to ensure that the node is ready to be enabled on the link. This mechanism uses the NS message ( ICMP 135 ) to complete the task by using the source address (::) and the destination address as the NS message of the requested node's multicast address corresponding to the obtained v6 address .
