Isis circuit-type level-1 interface Serial0/1 R1#sh ip bgp ipv6 unicast The simple horizontally separated rule is that the update message sent from an interface does not contain the network contained in the update received from the interface. In other words, the route I received from this interface will not be from this interface. Send it back. Route-map cisco permit 20 match ip address 2 set metric 10 ! Next hop 10.1.12.2, FastEthernet0/0 valid adjacency Image Image For Windows 7 systems, the IPv6 protocol stack is already installed by default . Prefix announcements are the initial mechanism for stateless autoconfiguration. Using RA ( ICMPv6 Type 134 ) and the multicast address of all nodes ( FF02::1 ), the router RA message is periodically sent to FF02::1 on the local link . Interface tunnel 0 We know that the AD value of a static route is 1. The above configuration method actually changes the AD value of the static route to 10 . In this way, we have two default routes, one for the telecom exit, the AD value is the default 1 ; the other points to the education network exit, and the AD value is 10 . Then after Redistribute bgp 234 Remarks Both Image Ipv6 unicast-routing interface Tunnel0 Reply to ISP1 , GW perceives through tracking , and the data is switched back to ISP1. Ipv6 route 2002:CA65:1703::/48 Tunnel0 R1 and R2 run RIP ; R2 and R3 establish OSPF neighbor relationships. In the initialization case, there are four entries in the routing table of R2 , as shown in the figure above, and there are only two entries in the routing table of R1 , that is, two direct links. So now, we do the re-release action on R2 , and redistribute the OSPF route to RIP , then the configuration is as follows: Ipv6 rip RIPprocess default-information originate Router bgp 300 Gateway (default route) Ipv6 nd reachable-time !! A neighbor confirmed after its accessibility by an event, during which time the neighbor is considered reachable, the default 30S (in CISCO IOS on the show out, the book says It’s 30min , it’s estimated to be wrong.)

At this time, the multicast data is actually going to R1, that is, to the receiver, but in fact, some more complicated things are still happening underneath. R1 receipt Register Thereafter, there will be formed the source wishes SPT , so it asks R2 issued a SPT of the join message, R2 after receiving own Fa0 / 0 is added to the corresponding port multicast table entry outgoing interface list of . However, since the multicast data is always sent from the Fa1/0 port of R2 (because when we tested, the specified outgoing interface is Fa1/0 ), R1 continuously receives the multicast data sent by R3 and encapsulates the multicast data. Register , but did not receive alongSPT passed down the multicast data, therefore, Rl is not to R3 transmits Register-STOP , R3 registration process can be repeated,ccna dumps quora, the multicast data will always be encapsulated in Register transmitted message Rl .
