Image On CISCO IOS , the default valid time is 30 days ( 2,592 000s ) and the prefer time is 7 days ( 604 800s ). RIP Version 2 Protocol Applicability Statement Host can send Exit-address-family Routing? The key point is that R2 , through the R2 deployment redistributed routing , routing information may be selected in different transmission routes between the domains. For address family: IPv6 Unicast Via FE80::FFFF:FE10:2, Serial0/0 Set tag 10 S0 DCE Field name Default route delivery Router bgp 300 address-family ipv6 Existing CISCO IOS of IS-IS supports IPv6 , the relevant RFC : 1195 IHL header length; Tunnel mode ipv6ip R* 0.0.0.0/0 [120/1] via 192.168.12.1, 00:00:03, Serial0/0 R2 's F0/0 port is configured with proxy ARP , 3.3.3.0 network R2 itself is reachable, so R2 will respond to this ARP request with its own F0/0 port MAC . In fact, this is an ARP spoofing behavior: ) Image !!

The valid range of the Solicited-node address is the local link range. Image The link layer address corresponding to the Layer 3 address is parsed by the neighbor request ( NS ) and the neighbor advertisement ( NA ) message. The GW configuration is as follows: 100.1.1.0/24 . At the same time, this re-release becomes the summary route of OSPF . Even if two ASBRs are returned , because there is a static summary route locally, the summary route of OSPF is directly ignored , and sub-optimal is not generated. Path, this route will not be re-released back to RIP and cause other problems. In the in direction, the distribution list can only filter the route when the LSA is received locally. When the route is generated, the router's own routing table that implements the distribution list will be affected by the distribution list (but the local LSDB still has the LSA ), and router will still LSADB in You can use the show cef interface command to check which load balancing mode is used. This command gives the CEF information configured on this interface .

Therefore, IPv6 IS-IS cannot be used on a remote IPv6 network connected through a tunnel . Configuring a tunnel is a static IPv6 over IPv4 tunnel. / / Mark the routing table 192.168.1.0 as the default network Route redirection Complete PE1 and PE2 , PE-CE routing protocol configuration, and MP-BGP configuration. Image RIP also supports tags , but it must be version 2 . Netflow switching We found that R1 created a cache, the identifier from 2012::1 to 2034::4 , PMTU=1400 , so R1 in the subsequent message sent to 2034::4 , if it exceeds 1400 bytes, R1 will Fragmentation, for example, we will test again, continue to ping 2034::4 on R1 , the message size is 1500 bytes, then: NS 135 Image test: length IS-IS Level-2 Link State Database: After 10.1.31.0 is passed to R2 , since R2 takes the mask of the receiving interface and finds that 10.1.31.0 has a position of 1 in the host part ,ccna 200-125 dumps online, the subnet is stored in the routing table and treated as a host route. : 10.1.31.0/32 After these packets arrive at R1 , the R1 router supports IPv4 and IPv6, which is a dual-stack router. R1 and R2 establish a tunnel to connect two IPv6 islands that are respectively hanged at R1 and R2 . The original IPv6 packet sent by the PC is added with an IPv4 tunnel header by R1 , forming a message that looks like an IPv4 packet. Thereafter, this message is routed in the IPv4 network and eventually reaches R2 . After receiving the "tunnel packet", R2 removes the IPv4 header of the packet and then restores the original IPv6 packet to the IPv6 network.
