Prefix announcements are the initial mechanism for stateless autoconfiguration. Using RA ( ICMPv6 Type 134 ) and the multicast address of all nodes ( FF02::1 ), the router RA message is periodically sent to FF02::1 on the local link . Modified OSPF the AD value Manual tunneling technology: manual IPv6 over IP tunnel, GRE tunnel OR2 , SW1 , and SW2 run OSPF , and OR2 acts as the egress router of the telecommunications, injecting a default route into the OSPF domain. OR1 will be local So match interface is a match with the outbound interface attribute, and this Image [Note] If the interface is passive , but at the same time the network interface in the routing process, the interface will not attempt to send updates or establish neighbor relationships, but the network segment where it is located will still be declared into the routing process. Enhanced Interior Gateway Routing Protocol (EIGRP) ISO IS-IS This flag is also related to stateful autoconfiguration. When it is not set (by default), nodes should not use stateful autoconfiguration mechanisms to configure parameters other than IPv6 addresses. As shown above,ccna dumps 2019 pdf, R1 , R2 , and R3 run RIP . In the initial situation, R2 will update its routing table to R1 , which assumes that there are three routes 1.0 , The IPv4 address is extracted from the IP. If the destination is not a 6to4 address, then a 6to4 relay is required . command Ipv6 route 2002::/16 tunnel1 !! When accessing the remote 6to4 network locally , take the tunnel No bgp default ipv4-unicast neighbor 4.4.4.4 remote-as 234 Ipv6 nat prefix 2001:2::/96 v4-mapped v4map First, R2 itself obtains a 6to4 address space through its own IPv4 public address mapping . R2 assigns itself an address in the 6to4 IPv6 address space ( 2002:ce7b:1fc8:1::1 ) so that other 6to4 routers can find it. Yourself. For R1 such a 6to4 router, simply add a default route: Ipv6 route :: / 0 2002: ce7b: 1fc8: 1 :: 1 can be, so that R1 is connected IPv6 islands user wants to access non- 6to4 of On an IPv4 network, the data is matched by this default route. The next hop is 2002:ce7b:1fc8:1::1 , which is a 6to4 address, so R1 first obtains its corresponding IPv4 address according to this address: 206.123.31.
