Connect A to the interface First ensure that R1 , R3 to 10.1.1.0 are routed,cisco ccna course, and test on R2 : Ip address 202.101.12.1 255.255.255.0 The GRE tunnel is a well-known standard tunneling technology that guarantees a stable and secure end-to-end link. IPv6 2001:34::/64 IS R3.00 Image Image Image Global command, statically specify RP They will be written in binary form, in fact, we only consider a third 8 bit group can be, because it is the only change Because IS-IS runs on top of the data link layer, that is, it runs on top of the link layer protocol and requires CLNP support. Therefore, IPv6 IS-IS cannot be used on a remote IPv6 network connected through a tunnel . Configuring a tunnel is a static IPv6 over IPv4 tunnel. On CISCO IOS , the default valid time is 30 days ( 2,592 000s ) and the prefer time is 7 days ( 604 800s ). Router ospf 100 Interface Serial0/0 ipv6 enable 2001:12::/64 Use the Linklocal address as the source address of the protocol packet and send a RIPng message to the neighboring RIPng router. Use FF02::9 as RIPng Test description: ping FF04::1 on R3 , Fa0/0 on the outbound interface Last retransmission scan length is 0, maximum is 0 Static ! The idea is the same as V6 access to V4 . Destination Address (Route Prefix): This is the destination network number associated with the route entry. A complete route prefix consists of: network number + prefix length ! Because IS-IS runs on top of the data link layer, that is, it runs on top of the link layer protocol and requires CLNP support. Therefore, IPv6 IS-IS cannot be used on a remote IPv6 network connected through a tunnel . Configuring a tunnel is a static IPv6 over IPv4 tunnel. 133 Interface loopback 0 Image Ipv6 address 2001:1::FFFF/64 ipv6 nat View the ipv6 address information of the network card , such as validity period, prefered lifetime, etc. ( ipconfig is also available) When ISP1 fails, GW senses through tracking , so the data is switched to ISP2. Image ...... Experimental needs 6000 – 7FFF Define multiple serial numbers under route-map . The serial number has a priority order when performing matching actions. Routing time: The time elapsed since the last time the routing entry was modified. The routing time is reset to 0 each time the routing entry is modified . V1 defaults to send v1 to receive v1, v2 Network None Complete the basic interface IP configuration . Add the following configuration on R2 : Detailed mechanism The configuration of R2 is as follows: Image Redistribute rip subnets route-map test Generally, the IPv6 address space applied from the operator is /48 , and further planning by yourself according to the needs: as shown below: !! wherein 2.2.2.2 is R2 of Router-ID , attention since 100.1.1.0 in R3 of OSPF We focus on the 2001:5555::5/128 route, the next hop is a strange address, but from the last 32bits of this address is 4.4.4.4 it is not difficult to see who passed this route to me, in addition, The out label of the prefix is 403 , and this 403 is exactly what PE2 passed to me. In other words, PE2 as 2001: 5555 :: 5/128 This IPv6 prefix assigned 403 labels, and pass this map to the PE1 , the label is actually MP-BGP generated. Then when PE1 has data to go to 2001:5555::5 is it directly labeled 403 ? Of course not, because the label 403 for MPLS Backbone in the P routers, do not understand, therefore, we also need an outer label, the label by the LDPGenerated so that our packets can be transmitted within the MPLS Backbone .
