Manual IPv6 over IP tunnel V6 Tunnel source Serial0/0 tunnel mode ipv6ip 6to4 RFC2082 Manual configuration Another problem with proxy ARP (from TCP/IP routing technology volume one) The configuration of A and B is extremely simple, so I won’t say it here. 32 bits R2 re-released the incoming A network segment route and then got up? Then R3 will ignore the route from R1 update. For R3 , go to None 1 : RIP-1 ; LSA flooding and aging mechanisms are the same Disadvantages: Each device needs to be configured with two protocols, which need to occupy resources. The device needs to store two routing tables (if it is a router), and each protocol needs to be processed independently. Run RIP between R1 and R2 (declare direct connection and their respective LOOPBACK ). At this time , the update package sent by R1 has the source address of 192.168.12.1 . Ipv6 ospf 100 area 0 interface serial0/1 The MTU value found by IPv6 PMTUD is cached by the source node. With CISCO IOS , show ipv6 mtu can be used to display the destination PMTUD value of each cache. The Permit/deny keyword has a different role in different deployment scenarios. An IPv6 single protocol network host A and ALG maintain an IPV6 session, and host A can send IPV6 data to the ALG . At the same time, Ip cef Network 192.168.23.2 0.0.0.0 area 0 distribute-list route-map test in The command distribute-list out works only on the routes being redistributed by the Autonomous System Boundary Routers (ASBRs) into OSPF. It can be applied to external type 2 and external type 1 routes, but not to intra-area and interarea routes. Solicitation request and Router Advertisement notification message. The former is used to discover the router and causes the router to send the Router. 0200 – 03FF [Test 3 ] Whether to support on-demand circuits Existing CISCO IOS of IS-IS supports IPv6 , the relevant RFC : 1195 1. Configure IPv6 IS-iS on the GRE tunnel. Ipv6 address 2001:8888::8/64 In direction On the other hand, after ISATAP is deployed on the router , the router also generates a tunnel interface to respond to the tunnel establishment request of the ISATAP host. The tunnel interface also generates the interface identifier. Address format is IANA reserved ISATAP of 32 bits Implementation points Let's start with the above picture, starting from 172.16.0.0/16 . The next network number we see is 172.16.10.0/24 , which is obviously obtained after applying the VLSM variable length subnet mask. a 172.16.0.0/16 a master class this network subnet . So the so-called subnet,ccna security dumps questions, we can understand as a network number obtained by "stretching" the mask or borrowing from the host bit based on the default mask length of the category to which the network number belongs. In fact, 172.16.0.0/16 is an interval that includes 172.16.10.0/24 .
