Holddown defaults to 0 , which means that the garbage-collect default 120S is not used. Match metric matches the route with the specified metric. match route-type matches the specified type of route match community matches the BGP community. Image Passive interface Ipv6 address 2001:45::5/64 router bgp 100 As can be seen from the results of the packet capture, there are two layers of label . After the label is packaged into the P router , the top-level LDP label is popped up due to the PHP mechanism . Then the label packet is transmitted to PE2 , and PE2 pops up MP-BGP . The label is restored to the original IPv6 data and then forwarded to CE2 . Wherein R2 is as follows: IPv6 transition technology Route-map test permit/deny 20 Image 0/0/0 696 *>i2001:5555::5/128 Ip route 10.1.12.0 255.255.255.0 10.1.1.2 ! RIP defines two types of request messages and response messages. Ipv6 enable interface Serial0/1 203/nolabel Both R1 and R2 are connected to the 2.2.2.0 network. At this time, R3 goes to ping 2.2.2.2 . Because the static route of the outgoing interface is used, R3 thinks that 2.2.2.0 is a locally connected network, so ARP request is sent , R1 , R2 , can receive the request message, and both respond to the request message (the premise two Then the routing table of R2 is as follows: IPV6 and subnetting Experimental steps and configuration R2(config)# access-list 1 deny 192.168.3.0 R2(config)# access-list 1 permit any R2(config)# router rip --- We see that the ICMPv6 message of this RS is the head of IPv6 , and the head of IPv6 is the head of IPv4 . Note the header of the outer IPv4 , the source is 1.1.1.1 , the purpose is 2.2.2.2 Image Neighbor 2023::3 activate Unused The difference between OSPF V2 and V3 : Associate the static route of the next hop [Experiment 4 ] There is a main class network; there is a subnet route (match),ccna dumps free download pdf 2017, the longest match 110 !! Sends a distribution update action to a RIPng interface to perform a distribution list. The interface must be in the in/out direction. The interface is optional. If no interface is configured, the interface takes effect. Tunnel interfaces do not necessarily need ipv6 address , of course, can also be configured v6 address, it does not affect traffic through the router configuration is complete, PC1 can ping through PC2 , Ethereal as follows: FF02::1 FF02::2 FF02::1:FFC4:0 Multicast 0000 010x xxxx xxxx Different prefixes (network number + mask, indispensable), belonging to different routes in the routing table No frame-relay inverse-arp ipv6 enable The forwarding entry is only (and the outgoing interface list is empty) and will not be processed further. These multicast data are then discarded at R2 . Interface FastEthernet0/0 ipv6 enable Reference material Authentication Unassigned R1#show ip cef 2.2.2.2 internal The configuration of R2 is as follows (basic configuration and OSPFv3 ): Frame-relay map ipv6 FE80::5C10:8CFF:FEE0:FE89 102 broadcast Case: Double Exit NAT 1/16 Image Both ends are common IPv6 networks, using regular global IPv6 addresses. Image Mpls ip Image Allocation Ip policy route-map x When OSPF to IBGP when routes are heavy, because the OSPF of AD than IBGP of AD should be small, so there is no problem of sub-optimal routing path or loop: 3 jumps. Metric: 0 Routers can learn routing entries in a variety of ways: static manual configuration, various dynamic routing protocols, and more. When the router learns two routes to the same destination from two different ways, the router compares the AD values ​​of the two routes , that is, the management distance, preferably the route with a small AD value. If the AD values ​​are equal, for example, the same routing protocol, the metric value is further compared . Of course, this also involves the working mechanism problem of different routing protocols, which is specifically discussed for different routing protocols. As shown in the following figure, R3 and R1 run the RIP protocol, and R3 establishes adjacency relationship with R2 through OSPF . Therefore, R3 learns the route to the destination 1.1.1.0/24 from RIP and OSPF . The two routes use R1 and R2 as the next hop respectively. Then R3 finally chooses the OSPF route to be loaded into the routing table, which is to use R2 as the actual destination.
