ccna cost

An IPv6 packet consists of a basic header plus zero or more extension headers plus an upper layer protocol unit. The meaning of several fields: Image length As shown above, the position of the line is 16+4=20 , so we get the summary address: 192.168.0.0/20 , which is the most accurate summary address. 10.1.31.0/24 This subnet has been successfully updated " 10.1.31.0 " because it is the same as the main source of the R1 update source interface . Image Tunnel destination 10.1.23.3 Run RIP between R1 and R2 (declare direct connection and their respective LOOPBACK ). At this time , the update package sent by R1 has the source address of 192.168.12.1 . Y The configuration of R3 is as follows: Ipv6 address 2001::FFFE/64 no ipv6 nd suppress-ra Image Ipv6 address test ::/64 eui-64 !! Use the obtained prefix ( test ), plus the EUI64 of this interface , to form the interface global ipv6 address Ipv6 route 2222::/64 FastEthernet0/0 FE80::CE01:1AFF:FEE4:0 Full: The unspecified address 0 address 0 :: 0: 0: 0: 0: 0: 0/128 or : / 128 PE1#show bgp ipv6 unicast 2001:5555::5/128 32 bits Then, if an OSPF process (this sentence may not be rigorous, everyone understands what I mean), the route can not be summarized, such as the following figure. In R1 the ip route 0.0.0.0 0.0.0.0 null 0 then re-released in a static routing process, but also to Abbreviation of IPv6 address ! BGP state = Established, up for 01:05:47 Matches the network number and prefix length in the route prefix to enhance the accuracy of the match. Use 224.0.0.9 Image IPv6 interface address: This TLV contains an IPv6 interface address ( 128bits ). The decimal value assigned to the IPv6 interface address TLV is 232. For IS HELLO PDUs , this TLV must contain the Linklocal address, but for LSPs , the TLV must contain a non- Linklocal address. ! On the Internet, like R2 such 6to4 relay router still a lot. There are some public 6to4 relays. E.g: Install the IPv6 protocol stack. At this time, Win7 will automatically generate an ISATAP tunnel virtual interface: Static route associated with the outbound interface When ISP1 fails,ccna cost, GW senses through tracking , so the data is switched to ISP2. Image First ensure that R1 , R3 to 10.1.1.0 are routed, and test on R2 : RIP V1 supports a maximum of 6 and defaults to 4 equivalent load balancing. And does not support verification. V2 supports verification. On R2 , in order to reach the network connected by R1 , R2 configures a tool that uses route summarization, referring to a summary route: 192.168.0.0/16 to R1 , although this does serve the purpose of network optimization, but this summary route Too "rough", it even includes the network segment on the R3 side, we call this behavior not accurate enough. Therefore, an ideal way is to use a "just right" summary route that includes these detailed routes, so that you can avoid the problem of insufficient aggregation.
