RA 134 Static route associated with the outbound interface None Distribute-list 1 in TCP No passive-interface fast 0/24 Image IPv4 source IPv4 destination Redistribution will only perform re-release actions on routes in the routing table. RIP version number: Modify the UDP port and multicast group address used by RIP . By default UDP521 and FF02::9 Exit-address-family NLRI : is a set of destinations, expressed as an IPv6 prefix. Ip route 3.3.3.0 255.255.255.0 serial 0/1 Network In ASBR when re-released many ways to modify the external LSA of TAG value. Passing the value of Tag The next hop address is 128bits Image ISATAP router establishes a tunnel and get IPv6 addresses, but also to be able to ping through 20001: 8888 :: 8 Image Open Shortest Path First (OSPF) Routing Information Protocol (RIP) Route map reference Prefix announcement overview IPV6 header improvement Image Access-list 1 permit 100.1.1.0 Image Router ospf 1 Therefore, we can redistribute the Ethernet port (the network segment) into RIPng on R1 and R3 . Focus on the configuration of GW : Tunnels ( the Tunnel ) Thinking question When one or more consecutive 16- bit fields are 0 , the ::: is available, but only one is allowed in the entire abbreviation: Version Image The address may also represent an interface node or not IP address can be used as the source of some packets IP address (such as the DAD message DHCP initialization process the client's source IP ). For IPv6 node is not acquired IPv6 scene addresses 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 Interface fa1/0 Ipv6 enable RIP re-advertises routes to OSPF : When the host communicates with other IPv6 hosts, it forwards from the tunnel interface and takes the IPv4 address from the next hop IPv6 address of the packet as the destination address of the IPv4 encapsulation. If the destination host is in the site, the next hop is the destination host itself. If the destination host is not in the site, the next hop is the address of the ISATAP router. Network 192.168.24.2 0.0.0.0 area 0 No off default route above configuration, adding a destined 13.0 network routing next hop is R3 , the PC to 13.0 data network switch to R3 proof ip default next-hop priority routing detail below, above Default route. Ipv6 unicast-routing interface Tunnel0 1 : Request message, requesting all or part of the routing information from the neighbor; Adjust the management distance of the routing protocol ...... 192.168.8.0/24 IP routing table ( IP Routing the Table ) RIP-1 Only 11 Set ip next-hop 10.2.2.2 Then do a simple test: Image Passive-interface Switched Both R1 and R2 are connected to the 2.2.2.0 network. At this time, R3 goes to ping 2.2.2.2 . Because the static route of the outgoing interface is used, R3 thinks that 2.2.2.0 is a locally connected network, so ARP request is sent , R1 , R2 , can receive the request message, and both respond to the request message (the premise two Test description: ping FF04::1 on R2 and Fa1/0 on the outbound interface The front is to use static routing. If dynamic routing protocol is used, the situation is different. For example, IGRP or EIGRP , the network specified by the ip default-network command must be obtained through IGRP or EIGRP (declaration,ccna certification test questions, learning or redistribution). ), the default route can be dynamically passed to other protocol routers. 8 bits None ! Neighbor FE80::CE01:8FF:FED8:10 remote-as 12 !! If you do not configure this command, once the BGP neighbor is specified , the default ipv4 neighbor will Network 192.168.20.0 0.0.0.255 area 1 Where the State if REACH represents a neighbor up; as STALE means that these neighbors in the last 30s inside is not reachable Image Virtual-PPP Virtual PPP interface In IPv6 , the options in v4 were moved to the extended header. An IPv6 packet may include zero or more extension headers. When multiple extension headers are used, the extension header after the extension header is indicated by the Nexthead field of the previous header. With the extended header, the intermediate router does not need to deal with every possible option, which increases the speed at which the router processes packets and improves its forwarding performance. At the end of the extended header chain is the payload.
