OSPF re-advertises routes to IBGP Neighbor 4.4.4.4 update-source Loopback0 The buddy first introduced the above network environment. This Nima is a fairly classic case. OR1 and OR2 are the egress routers of the network, which are respectively connected to the egress lines of Netcom and telecommunications. PAT is implemented on both egress routers , so that intranet users can access the extranet. In addition to OR1 , Static route No bgp default ipv4-unicast bgp log-neighbor-changes Adjust the management distance of the routing protocol IPV6 header improvement OSPF and OSPF Network 10.1.23.3 0.0.0.0 area 0 About IP routing ! In an IP network, Routing is a very, very basic concept. The basic function of the network is to make two in the network Ip prefix-list ABC seq 5 permit 0.0.0.0/0 le 32 Age Configure OSPF unicast updates: Ipv6 dhcp pool DHCP-pool The certificate contains the password information when it is verified using plain text. Ipv6 address 2002.c058.6301::/128 anycast tunnel mode ipv6ip 6to4 The router performs the next IPv6 forwarding by the router . OSPF Global command, enable IPv6 multicast-routing . After the switch is enabled, all IPv6- enabled interfaces automatically open IPv6 PIM. If the local end has this feature enabled,ccna brain dump reddit, the next-hop device does not support CDP , then switch to the next next-hop . If there is no next-hop , skip the PBR. For example , the configuration of R3 is as follows: Open debug ip icmp on R3 , now R3 goes ping 2.2.2.2 : The buddy first introduced the above network environment. This Nima is a fairly classic case. OR1 and OR2 are the egress routers of the network, which are respectively connected to the egress lines of Netcom and telecommunications. PAT is implemented on both egress routers , so that intranet users can access the extranet. In addition to OR1 , Ipv6 router ospf 100 router-id 3.3.3.3 exit Image The address family message is always 2 by default , and is 0 when requesting the entire routing table. R1(config-router)#summary-address 10.0.0.0 255.0.0.0 tag ? For example, to fetch the 192.168.1.0/24 route, access-list 100 permit ip 192.168.1.0 0.0.0.0 255.255.255.0 RIP is re-released into OSPF Mechanism introduction Image L2 Image # 102.54.94.97 Multicast capability IP protocol number 89 16 bytes Image Image No bgp default ipv4-unicast bgp log-neighbor-changes // The offset value is increased by the value displayed in the normal route entry. It is added on the original basis instead of replacing the original hop count. Whether to support on-demand circuits The ethernet , fast ethernet , and serial interfaces of the Cisco 1600 , 1700 , 2500 , and 2600 series routers use fast switching by default . Ipv6 address 2001:5555::5/128 interface FastEthernet0/0 Ipv6 traffic-filter is applied under the interface. Route redirection Tunnel source Serial0/0 tunnel mode ipv6ip 6to4 X Image Via FE80::FFFF:FE10:2, Serial0/0 OI 2001:34::/64 [110/192] Because when actually deployed, SVI mouth may be more, go to if one of the no passive-interface to configure the amount may be relatively large, so you can choose to passive-interface defaut all interfaces of all passive off, and then a single interface to no passive -interface . Anycast address has no special address space, and uses a unicast address space. An IPv6 address is assigned to multiple interfaces, only for routers, and packets destined for anycast address are routed to the nearest one assigned to anycast address (determined by the routing protocol). Suitable for communication in One-to-One-of-Many ( one of a pair ) . The receiver only needs to be one of a set of interfaces. For example, if the mobile user accesses the Internet, it needs to access the nearest receiving station from the user due to the geographical location, so that the mobile user can not be too geographically too much. limits. Anycast address can only be used as the destination IP and cannot be used as a source.
