Implementation of two-point bidirectional routing re-release About the prefix list 1/8 Mechanism involved Must be zero Timer verification !! ipv6 routing, all traffic to the IPv6 network is thrown into the tunnel Certification IP CEF turbo control turbo vector Interface fast0/0 Ipv6 enable Interface FastEthernet1/0 In R2 on a simple look: Ipv6 ospf 100 area 0 Ipv6 address 2001:1::FFFF/64 ipv6 nat Deployment points The router goes to update the route of 3.0.0.0 1/256 Image Defaut-network takes precedence and becomes the default gateway gateway of last resort . However, if the network specified by ip defaut-network is learned from a dynamic routing protocol, ip route 0/0 takes precedence. # 102.54.94.97 The configuration of R1 is as follows: lab environment Corresponding hwidb fast_if_number 4 Corresponding hwidb firstsw->if_number 4 Internet address is 10.1.12.2/24 Routing. So go to both network segments and go to R1 . So if we want to go to 11.11.11.0 and take R3 , so that these two destinations can be diverted? We can choose to route the source from 10.1.12.1 in the EIGRP process of R2 . 2001:1111::1/128 2001:12::1 204/nolabel Type escape sequence to abort. Prefix re-addressing [Experiment 2 ] Both IPv6 islands use ordinary IPv6 global addresses. R1 , R2 , and R3 run RIP and only announce the direct link between the three. In R1 the ip default-network 172.16.0.0 !! activated RIP !! ipv4 routing, so that the route can access the tunnel destination , which is 10.1.23.3 Y Ipv6 nd prefix 2001:0001::/64 696 MTU Image PE1 , P , and PE2 form an LDP neighbor relationship and deliver IGP labels. In order to facilitate the observation of experimental phenomena, the label range of PE1 is set to Ip sla monitor 1 Image 172.16.10.1 ,ccna test answers, in fact, this IP may be understood as 172.16.0.0/16 within the network, but also in 172.16.10.0/24 within the network, of course, here we can see it, then who is more accurate? It is clear that 172.16.10.0/24 is more accurate, we say that its matching length is longer than 172.16.0.0 . After these packets arrive at R1 , the R1 router supports IPv4 and IPv6, which is a dual-stack router. R1 and R2 establish a tunnel to connect two IPv6 islands that are respectively hanged at R1 and R2 . The original IPv6 packet sent by the PC is added with an IPv4 tunnel header by R1 , forming a message that looks like an IPv4 packet. Thereafter, this message is routed in the IPv4 network and eventually reaches R2 . After receiving the "tunnel packet", R2 removes the IPv4 header of the packet and then restores the original IPv6 packet to the IPv6 network.
