Ipv6 unicast-routing LSP Seq Num Next , summarize the loopback route of R1 on R2 : Aggregate global unicast address ( IANA to registers ) !! configure validtime and preferd time , this is a relative time If you want to turn off ICMP redirects, you need to use no ip redirects on the interface . Ipv6 ospf 1 area 0 Ip address 1.1.1.254 255.255.255.0 Interface FastEthernet0/0 ipv6 ospf 1 area 0 Route-map PBR permit 10 match ip address 1 Interface FastEthernet0/1 Image IPv4 Ipv6 enable 136 OI 2001:1:1::1/128 [110/192] Image Ipv6 route 2002:CA65:C01::/48 Tunnel0 The IPv6 address that the node must have : Image Image ( Routing Table ) , the routing table is loaded with routing entries ( routes ) learned by the router . The routing entries are composed of routing prefixes (destinations associated with routes), routing information sources, outgoing interfaces, or next hop IPs . The router obtains routing entries and maintains its own routing table in a static or dynamic manner. Bgp router-id 5.5.5.5 NDP can help us achieve the following features: Status codes: s suppressed, d damped, h history, * valid, > best, i - internal, r RIB-failure, S Stale ! Address structure Update behavior Ip route 192.168.1.0 255.255.255.0 172.16.12.1 C 192.168.12.0/24 is directly connected, Serial0/0 1.0.0.0/24 is subnetted, 1 subnets Valid lifetime is similar to dhcp in the Lease Time . If the address exceeds the valid lifetime , the node will set this address to inactive and then delete . Between the preferred time and the valid lifetime is called the deprecated state. This state is a buffer . It is probably a deprecated state. When the address reaches this time period,ccna course material, the address cannot be actively initiated. The connection can only be passively accepted. Connection, this is also designed to ensure the upper layer application, but after the valid lifetime time address becomes invalid , then any connection will be down .
