Label associated with the VPNV6 prefix: Ipv6 unicast-routing interface Tunnel0 Prefix Image Image At another point, R2 will take 10.0.0.0 , 11.0.0.0 (the network segment where the secondary address is located), and 1.0.0.0 and 3.3.3.0 from their own loopback. Metric B removes the IPv4 header of the packet , obtains the original IPv6 data, and forwards it to PC2 .

FastEthernet1/0 Image Path control In the figure above, the first two packets are the two fragments of the ICMPv6 message sent by R1 to R4 , and the third message is the reply package of R4 . The header forms an outer IPv4 packet, which is routed in the IPv4 network. Ipv6 unicast-routing NS 135 R2(config-router)#redistribute rip subnets 10.1.13.3 Use " clear ipv6 neighbors " to clear the dynamic entries in the neighbor discovery table. LSP Seq Num LSP Checksum LSP Holdtime The verification of Layer 2 and Layer 4 is already robust enough, so IPv6 directly cancels the Layer 3 check of IP . If the RA packet contains authentication information, then the authentication is correct Dialer Dialer interface This path. And because there is no RIP route in the routing table , the natural RIP re-release to OSPF fails, and even worse, R4 about Address Ip route 0.0.0.0 0.0.0.0 202.101.12.2 Neighbor 2001:12::2 activate network 2001:1111::1/128 !! 4.4.4.4 is also PE2 No shutdown interface loopback 0 Modify the timer.

Route-map PBR permit 20 match ip address 2 Router responds to this RA where there is a ICMPv6 of the Option , which contains the ISATAP router IPv6 prefix. and DAD ! NAT-PT is recommended when single-protocol networks need to communicate with each other . Frame-relay map ipv6 FE80::5C10:8CFF:FEE0:FE89 102 broadcast R5 release B segment RIP routing, R2 and R3 can learn, at the moment we are in R2 and R3 are on to OSPF to inject RIP routing, assuming that R2 injected first, then the B route will be R1 update to R3 , R3 this When you learn B routing from both RIP and OSPF , then it will: Pointer to the target: The pointer does not point to the router's direct connection to the destination network or to another router address in the directly connected network , or to the local interface of the link. A router that is closer to the target network is called a next hop router. Image OR2 configuration ! Common basic configuration IPv6 Address(es): FE80::FFFF:FE10:1 Route-map OSPF3to1 permit 10 match tag 10 FF02::1 link local range all node multicast address R1 ICMPv6 messages used by the NDP mechanism : [Note] The process name is valid locally. If the two interfaces are enabled on the Router and RIPng is enabled with two different process names, the two processes are independent of each other. The IPv6 address that the node must have : Mpls label range 300 399 mpls ldp router-id Loopback0 interface Loopback0 Cannot be included in route calculation Access-list 1 permit 3.3.3.0 router rip 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. MTU is 1500 bytes Experimental phenomena: In the above circumvention scheme, we use ACL to match the route directly , and then call it in the distribution list. This method is not scalable. If there are too many routing entries re-advertised into OSPF , the ACL entry will be crazy. So we try to have a method with a more scalable, for example, in R3 on the RIP redistributed into OSPF , when injected into the route marked Tag ,ccna dumps 2018, then what in R2 when on deployment distribution list, you You can associate a route-map to "crawl" these routes with tags .
