Router ospf1 Match x4 set Y The stateful configuration is obtained by hand or by dhcpv6 , and stateless is obtained by prefix advertisement . Either way, the address obtained will have several time states. OSPF 's neighbor command is not the same as EIGRP . After testing, in the Ethernet environment, directly refer to the neighbor , and still send multicast hello. View IPv6 routes Image X.acme.com In the above figure, there is a problem with the network on the left side. The L2 router of the IPv4 single protocol does not support IPv6 , thus destroying the continuity of the IPv6 L2 router . The network on the right is the correct structure. When track1 is true , that is, 10.1.1.2 is reachable, the data of the PC accessing the 100 network is lost to 10.1.1.2 . If track 1 is hung, the next next-hop is switched. 00 ! In the area 1 via interface Serial0/0 Netsh interface ipv6 show route Image Then the received route becomes 10.1.20.0/24 and the mask is correct . Interface Serial0/0 ipv6 enable Prefix re-addressing Switching is the process of mapping layer 2 to layer 3 addresses andforwarding to a destination interface. Address family Router ospf 1 Ip route 2.2.2.0 255.255.255.0 192.168.123.2 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 Tunnel destination 10.1.23.3 PE1 , P , and PE2 form an LDP neighbor relationship and deliver IGP labels. In order to facilitate the observation of experimental phenomena, the label range of PE1 is set to Image Experimental phenomena: Scanning messages on the intranet. The destination addresses of these packets are some unknown addresses that start with 192.168 , or even addresses that do not exist at all. The packet is sent to the gateway, which is the Layer 3 switch. Since the Layer 3 switch is configured with the default route, these packet destinations are matched by the default route and directed to the egress router,ccna sample exam, and the summary route is deployed on the egress router. Although the destination address of the packet does not exist in the internal network, it is an IP in the summary route , so it is forwarded back to the Layer 3 switch by the egress router. Then the Layer 3 switch forwards the packet according to the default route. Back to the router, this forms a loop of data.
