In this arbitrary play prefix, if the defined IPv4 address of the nearest 6to4 relay is 192.88.99.1 , then the address is The OSPFv3 header removes the authentication related fields in v2 . This is because the ipv6 header already has a good authentication function.

These multicast data arrive at R3 , since R3 is the first hop router, and the Fa0/0 port of R3 is the DR of the local LAN , so 0xA440 None Redistribute ospf 1 route-map test !

The update is sent. At this time, both parties have their own routes, but 1.1.1.1 cannot ping with 2.2.2.2 . FE80::CE00:10FF:FE58:0 If you need to run a dynamic routing protocol between R1 and R3 , you can activate the routing protocol on the tunnel interface. Image Ip route 0.0.0.0 0.0.0.0 202.101.23.2 Identify the type of message: Route summary The configuration of R4 is as follows: Hostname: R4 In the example, the static route associated with the next hop does not have this attribute, so it is not matched. The example here is DHCPv6 , using Router as the DHCPserver !! no-autoconfig is related to A bit, as defined in RFC2461 . The A bit also becomes an autonomous address configuration flag. When this optional keyword no-autoconfig is configured in CISCO IOS (that is, with the above command), the A bit is set to 0 . If the A bit is set to 1 (the default is 1 ), it indicates that the host on the local link can use this prefix for stateless autoconfiguration. ! Situation 3 Border Gateway Protocol (BGP) Connected A distribution list is a tool used to control routing updates. It only filters routing information and cannot filter LSAs . Therefore: the distribution list is used in the distance vector routing protocol, and the route can be filtered normally in either in or out direction. But the work in the link state routing protocol is a bit problematic. Show ip cef detail After " 10.1.20.0 " is passed to R2 , since the updated subnet is consistent with the R2 interface main network, R2 receives the update, and uses the interface mask /23 as the mask of the received RIP subnet, then R2 local loading This RIP route is 10.1.20.0/23 . In fact, the prefix length of the route is wrong. We can configure a secondary address on the R2 interface. In this way, RIP will use the mask of the secondary address (if configured) to receive the route. For example,ccna dumps pdf free download, configure R2 with 10.1.123.222/24 .
