Ipv6 address 2001:34::4/64 supplement: ! Define multiple serial numbers under route-map . The serial number has a priority order when performing matching actions. Netsh interface ipv6 reset Use " ipv6 neighbor ipv6 address interface number mac address" to add a static entry to the neighbor discovery table, for example: Le le-value Route-map usage scenario IS-IS Level-1 Link State Database: FE80 – FEBF Provide a better next hop address. If it is 0.0.0.0 , it means the way to publish this route. 100x xxxx xxxx xxxx IPv4/IPv6 Application Prefix readdressing 2012::2 RIPng ::FFFF: 4.4.4.4 Neighbor 2002::2 remote-as 12 address-family ipv6 --- Access-list 1 permit 192.168.1.0 Address 10.1.12.1(10) Configure OSPF unicast updates: !! Neighbor 4.4.4.4 is also PE2 , activate VPNv6 support ability Local site address (Site-local address) Used for automatic address configuration, neighbor discovery, router discovery, etc. The router queries through recursion, the next hop 2002: CA65:1703::FFFF should be thrown to tunnel0 , and tunnel0 is a 6to4 tunnel, so the 2002:CA65:1703::FFFF is translated into the corresponding V4 address, which is 202.101.23.3 Image Neighbor FE80::CE01:8FF:FED8:10 remote-as 12 neighbor FE80::CE01:8FF:FED8:10 password cisco 192.168.1.0/24 Linklocal address, and IPv6 global unicast address. This will be described below. In the above figure,ccna security dumps free download, R1 and R3 will update routes 1.1.1.0 and 11.11.11.0 to R2 . Of course, by default, R2 is definitely the preferred EIGRP. 2 : link local range; eg FF02::1 indicates all nodes on the link; FF02::9 : indicates all RIP routers on the link Image Situation 3 The three routers are configured with RIPng and require network connectivity. Path control 2.2.2.254 , which is the default gateway for ISATAP routers. No-rtr-address off-link The IS-IS domain is based on a two-layer structure, Level1 and Level2 , and the concepts of L1-router , L2-router, and L1L2-router , and IPv4 IS-IS . Header format 202.101.100.100 Redirect message No frame-relay inverse-arp ipv6 enable That's what I mean No bgp default ipv4-unicast neighbor 2001::1 remote-as 12 Stateful address autoconfiguration ( DHCPv6 ) 1 There are two general ways to automatically configure an IPv6 address: OSPF and RIP Gateway of last resort is not set 9.0.0.0/24 is subnetted, 2 subnets A and B respectively use this IPv4 public network address to map to get the 6to4 address space. The 6to4 address space uses 2002::/16 , and the 6to4 address is formed as follows: Cancel the fragmentation function of the intermediate node Router isis When the router is in the boot mode and the software is upgraded, the ip routing is also closed, so the command will be used when necessary. Image Image The configuration of R3 is as follows: R 3.0.0.0/8 is possibly down , routing via 9.9.12.2, FastEthernet0/0 Hostname: R4 Redistribute ospf 3 subnets route-map OSPF3to2 Authentication Type Ip default-network 192.168.1.0 Set ip next-hop { ip-address [...ip-address] | recursive ip-address } The header forms an outer IPv4 packet, which is routed in the IPv4 network. Ipv6 address 2001:12::1/64 FE80 – FEBF The PMTU will become 1300 bytes.

After the match lives, the packet is first sent to the first next-hop ip address . If the direct connection associated with the ip address is DOWN , then the next next-hop ip address is switched . Multiple next-hop . However, if the directly connected next-hop (the peer router or its interface) hangs itself, and the local direct interface is not perceived (such as the middle switch ), it cannot be automatically switched, and the router will still put the data in the brain. Throw it to this next-hop .
