Router eigrp 100
6PE : 6PE technology relies on BGP , BGP 's Peer is the need to manually specify, it can be regarded as a semi-automatic tunneling technology.

Although the decision to forward the message is implemented by the FIB , the second layer of frame rewriting is done according to the information in the adjacency list. The second layer needs to be rewritten to include the second layer for frame forwarding. head. For Ethernet, it is the new source, destination MAC , and type field. E.g:
R1(config-router)#summary-address 10.0.0.0 255.0.0.0 tag ?
Use " ipv6 neighbor ipv6 address interface number mac address" to add a static entry to the neighbor discovery table, for example:
Bgp router-id 184.108.40.206
R2 becomes the demarcation point between RIP and OSPF domains. So how can I let R1 learn the route from OSPF and let R3 learn from RIP?
FE80:: 5EFE:202:202 2001:1111:: 5EFE:202:202
The interface will only receive updates, no updates will be sent.
RIP Version 2 Carrying Additional Information
In the above figure, we inject OSPF routes into RIP . Traditionally, you can only set metrics on all incoming routes . However, with route-map , we can associate a defined one when configuring re-issue commands. A good route-map , in the route-map , we can create different properties or actions for different routes by creating multiple serial number statements.

Redistribution will only perform re-release actions on routes in the routing table.

If R2 is added to the default route of R3 on the above basis, the data of the PC to the 10.1.13.0 network is still lost to R1 , which means that ip defaut-next-hop has higher priority than the default route.
Redistribute connected level-1 exit-address-family
Ip route 0.0.0.0 0.0.0.0 10.1.12.2 !! ipv4 routing, so that the route can access the tunnel destination , which is 10.1.23.3
Wherein R2 is as follows:
IPv6 has some special multicast addresses, which have special meanings.
After this time has elapsed, the route entry will become 16 hops, marking the unreachable route possibly down . Gateway of last resort is not set
After 10.30.0 is passed to R3 , since the RIP updated subnet and the R3 interface subnet belong to the same main class network, R3 receives the update, and uses the interface mask as the mask of the RIP route, so the R3 routing table The route loaded in is: 10.1.20.0/24
Verify again, instead of detailed routing, use a summary route of ip route 10.0.0.0 255.0.0.0 , the next hop is R3 , the effect is the same as above, also take R3 . Therefore, as long as it is not the default route, as long as there is such a matching route in the routing table, the route is taken preferentially, and the route-map is taken without the route .

Authentication is identified by setting the address family ID field to all 1s ( 0xFFFF ).

Note that at this time, in the routing table of R2 , the 3.0 route is killed. Note that, in fact this time,ccna dumps 2019 free, Area within OSPF routers generated LSA has been loaded into the R2 of the OSPF Database alone rather than in R2 from the OSPF Database calculated route and prepares route entry is loaded into the routing table before, in the distribution direction play a role in the list, the 3.0 routes filtered out, so R2 routing table, there is no 3.0 the OSPF routing. However, although there is no 3.0 route in R2's own routing table , this does not prevent R2 from flooding the relevant LSA to R3 . Therefore, R3 still has 1.0 , 2.0 ,3.0 and 12.0 of the OSPF routing.
