!! interface associated with VRF cisco ND reachable time is 30000 milliseconds Image Image Used for automatic address configuration, neighbor discovery, router discovery, etc. No bgp default ipv4-unicast neighbor 4.4.4.4 remote-as 234 Image 6to4 automatic tunnel Note that the IPv4 prefix 192.88.99.0/24 here should be published to the routing protocol on the IPv4 Internet. Otherwise this 6to4 relay using the anycast prefix is unreachable in the IPv4 Internet. 001x xxxx xxxx xxxx In the above figure, there is a problem with the network on the left side. The L2 router of the IPv4 single protocol does not support IPv6 , thus destroying the continuity of the IPv6 L2 router . The network on the right is the correct structure. When the network is normal, the data is forced to go ISP1 , ping 100 remote network data to ISP1 Ipv6 route ::/0 tunnel 0 IPv6 Routing Table - 12 entries FE80::CE02:8FF:FED8:0: martian next hop R2# Whether the hop limit of the IPv6 header of the RA packet is 255 . Because only 255 means that it is generated by the router in the local network. Interface FastEthernet0/0 ipv6 enable R1 RIPv1 !! NET entity address The summary of the route is actually done by the operation of the subnet mask. For the following example: Image RIP database Tunnel mode ipv6ip tunnel source serial 0/0 Router(config-router)#redistribute ? The next hop address is 128bits BGP state = Established,ccna questions, up for 01:05:47 Interface Serial0/0 In fact, there are two main lifetimes of IPv6 addresses , one is Valid lifetime and the other is preferred lifetime . First in ! Router(config) router rip Ipv6 unicast-routing Configure static routes by using the associated outbound interface. Bgp router-id 1.1.1.1 Router(config-router)# First ensure that R1 , R3 to 10.1.1.0 are routed, and test on R2 : X RIPng Ipv6 unicast-routing ipv6 cef Use " ipv6 neighbor ipv6 address interface number mac address" to add a static entry to the neighbor discovery table, for example: And fe80:0000:0000:0000: 0000:5efe : for private addresses with the 32 bits of the host's IPv4 address. ". Looks like there is a globally unique and private point, but more than 0200 found in the relevant draft of the IETF :5efe description, in my test environment, the system used on the Windows host is 0200:5ede , and the CISCO router uses 0000:5efe . Redistribute bgp 234 Redistribute ospf 3 subnets route-map OSPF3to2 Request message: You can request the entire routing table or request specific routing information. Image Link-local address :: REACH OE2 2004:1:2::/64 [110/20] Set ip next-hop verify-availability [ next-hop-address sequence track object ] Internal EIGRP OSPFv3 uses the IPv6 Linklocal address to identify OSPFv3 neighbors. Address-family ipv4 The final results are first PC to be able to ping through ISATAP Router 's IPv4 address is 2.2.2.2 . Then PC with Other orders In R2 on a simple look: Ip route 10.1.12.0 255.255.255.0 10.1.1.2 Packet-based load balancing and process switching. Process exchange is for each packet , the router must perform routing table query and interface selection , and then query the data link information. Because each process that determines the routing of packets is independent of each other , all packets destined for the same target network are not forced to use the same interface. In order to open the process exchange function on the interface , you can use the command no ip route-cache under the interface . For IPv6 nothing needs to be done , because by default the feature is turned on.
