OSPF 's neighbor command is not the same as EIGRP . After testing, in the Ethernet environment, directly refer to the neighbor ,ccna exam cram, and still send multicast hello. Ipv6 enable Route-map OSPF3to2 permit 20 match tag 20 Ipv6 address 2001::1/64 Tag Address does not need R1(config)# interface fast0/0 R1(config-if)# ipv6 enable Single match includes a plurality of conditional statements, logical or operation; multiple match when the statement, using the logic and operation. On R1 , only the summary route 32.0/21 is filtered, and all the detailed routes are released. If a standard ACL is used to match the route, how to write it?

Image Cannot be included in route calculation length You should know that each routing protocol has different understandings of routing metric metrics . OSPF uses cost overhead to measure a route, RIP uses hops, and EIGRP uses mixed elements, so when I Some routes, from one of the routing protocols to another routing protocol, how will the metrics of these routes change? One way is that you can manually modify the re-release action when you perform the re-release action, depending on the specific environmental requirements, we will not worry about this later, the buddy is so sincere :). The second way is to use the default action, which is the seed metric defined when republishing between routing protocols.
