Mechanism introduction Vrf definition cisco rd 1:1 RFC2766 , RFC2765 . NAT-PT (Network Address Translation - Protocol Translation) is an address translation technique that translates IPv6 addresses into IPv4 addresses and vice versa. NAT-PT is based on the stateless IP/ICMP converter ( SIIT ) algorithm defined in RFC2766 . SIIT algorithm translation Establish BGP4+ neighbor relationships and pass IPv6 routes using IPv6 Linklocal addresses . Floating static route IPv6 reachability: This TLV defines such things as IPv6 routing prefixes, metrics, and some option bits. Assigned to IPv6 reachability ! If ReachableTime (default 30S ) is passed in the reachable state, the entry status of B on the A router is Reachable->stale Image R2 , R3 , aiming RIP create static routing domain summary route, point null0 , while only these static routes redistributed into OSPF , and indeed can play a sub-optimal paths to avoid the question, but: Mpls label range 400 499 mpls ldp router-id Loopback0 Interface Serial0/0 ipv6 enable Protocol ID: 0x0800 Manual configuration 1/32 2002 : IPv4 address : Subnet ID : The IPv4 address above the interface ID is the public network IPv4 address obtained by A or B. Note that this public network IP is very important. This public network IP change may lead to IPv6. Intranet IPv6 had to be readdressed. And, of course, this IPv4 address cannot use a private IPv4 address. technical background It is deployed on R1 and has an effect on these three routes. Ipv6 local pool dhcppool 2001::/64 64 interface Serial0/0 R1 and R2 are in AS12 , and OSPFv3 is running in the AS , so that R1 and R2 can learn the loopback route of the other party. Outgoing FF02::2 link local range all router multicast addresses Ip route 100.0.0.0 255.0.0.0 null0 Image Using this feature may reduce the performance of the device to a certain extent. In addition, you must ensure that CDP is enabled for both the neighbor and the router interface . Process switching and CEF support this feature, but dCEF does not. ! 16 bits Interface FastEthernet0/1 Offset-list offset list Experiment 4 The problem is similar to that mentioned above. Both R2 and R3 can learn to update the BGP B network segment route from R4 . Suppose R2 republish do first, then B routes will be injected into the OSPF , the finally R3 learned, then R3 , the same time from the OSPF and IBGP learned this route, will preferably OSPF , since OSPF is AD smaller. As a result,ccna exam dumps 2018 free, on R3 , the redistribution of IBGP to OSPF fails because the route of the B network segment is not BGP in the routing table . Furthermore, R3 has been re-released in both directions. Therefore , the route of the B network segment will be re-released back to IBGP . Since then, there may be a series of problems such as sub-optimal paths and loops.
