command FF01::1 ; FF02::1 R4#sh ip ro 192.168.1.0 Image Use this command to view the router IPv6 routing table. Ipv6 address 2000:12::1/64 ipv6 ospf network point-to-point ipv6 ospf 1 area 0 0xA440 Source of routing information: How is this route learned, for example, static, or through OSPF , IS-IS , About PBR Address-family ipv6 Valid lifetime 2591944 preferred lifetime 604744 Joined group address(es): 0 packets, 0 bytes switched through the prefix tmstats: external 0 packets, 0 bytes When a node starts the IPv6 protocol stack, each interface of the node automatically configures a link-local address. This mechanism allows two IPv6 nodes connected to the same link to communicate without any configuration. The default gateway recommends using a link-local address because this address is the most stable. In the authentication section, the authentication method defined in OSPFv2 is not used . Instead, use AH and ESP to extend the header as a security mechanism. ! Image Image !! Reveal the IPv6 route prefix learned from CE1 into BGP. BGP router identifier 2.2.2.2, local AS number 12 BGP table version is 1, main routing table version 1 Interface FastEthernet1/0 Image Ip address 202.101.23.3 255.255.255.0 Neighbor 4.4.4.4 send-label redistribute connected redistribute ospf 1 IP protocol number 89 (1) can learn the routing entries of R2 update, and the routing table is loaded with Unused Tag 1111, type extern 2, forward metric 64 In stateless autoconfiguration, the prefix length is 64 bits. After completing the configuration, R2 show ip route Image Unassigned Neighbor 2001:45::5 activate The configuration of R2 is as follows: If multiple next hop IPs are defined , when the local outbound interface associated with the first next hop is DOWN , it automatically switches to the next next-hop . *> 2003::3/128 X BGP state = Established, up for 01:05:47 Exit-address-family Open debug ip icmp on R3 , now R3 goes ping 2.2.2.2 : Interface Loopback0 Aggregate Y If multiple next hop IPs are defined , when the local outbound interface associated with the first next hop is DOWN , it automatically switches to the next next-hop . supplement: Routing Feedback (feedback) is a re-release in the deployment of routing requires a great attention to the phenomenon. As shown above, R5 will The router uses this information to construct a new Layer 2 header for the data frame and then forwards the message to the outbound interface pointing to the next hop. 16 Ip address 10.1.23.3 255.255.255.0 Address-family ipv6 [Test 3 ] // The offset value is increased by the value displayed in the normal route entry. It is added on the original basis instead of replacing the original hop count. State Image 2001::CE00:DFF:FE48:0, subnet is 2001::/64 [PRE] !! The status is prefer Experimental needs Set next-hop specifies the address of the next hop , specifying the next hop of BGP . Ip cef Image Access-list 2 permit 10.1.2.0 route-map cisco permit 10 The configuration of R2 is as follows (basic configuration and OSPFv3 ): Ip address 1.1.1.254 255.255.255.0 Other orders Ipv6 address 2001:23::3/64 interface Serial0/1 The router performs the next IPv6 forwarding by the router . 1) The above example, A received the IPv4 public network address: 132.214.1.10 , the mapping obtained 2002: 84d6: 010a :: / 48 , part of this address space was eventually used on PC1 . Now, PC1 will send an IPv6 data to PC2 . The source of this data IP is PC1 of 300 ? / / Is to shield the route from the RIP re-released in addition to 1.1.1.0 , and re-release the local direct connection Exit-address-family So when R1 sends a big packet to R4 , there will be no problem. This is fragmented directly at the source of R1 . Of course, we can continue to experiment, set the IPv6 MTU to 1300 bytes on the Fa1/0 interface of R3 , and then continue R1 to ping the big packet to R4 , and finally the cache entry on R1 . Traffic share 1 8 bits Image Command summary !

Therefore, BGP4+ can carry routing information for IPv6 and other protocols including IPv4 . RFC2858 and RFC2545 defines the BGP4 + process IPv6 attributes updated. Traffic share 1 Tunnel Tunnel interface Address-family ipv4 Route-map PBR permit 10 match ip address 1 meaning Case: Implementing intranet export data diversion through PBR Use this command to view the router IPv6 routing table. OSPF 's neighbor command is not the same as EIGRP . After testing, in the Ethernet environment, directly refer to the neighbor , and still send multicast hello.

Therefore, on R2 , the extra routes are filtered out, and only the F1 and 0- port routes of R3 are advertised to R1 . We filter out specific routes on R2 : Phenomenon analysis: This environment is not the same as before. First, the multicast data from R3 to Loopback0 port, then the First-hop router becomes R3 , instead of R2 a. Then R3 is the first hop router. After receivingthe multicast data sent by themulticast source (that is, its own LO0 ), R3 will trigger the Register process.The details of the register process are very familiar to everyone. winded, the end result is, R3 to R1 construct a SPF , from the reason that R3 Loopback0 port,ccna r&s exam dumps, sent to a multicast group FF04 :: 1 may be multicast data along the route R2 to R1 of SPF forward.
