Distribute-list 1 out rip As can be seen from the results of the packet capture, there are two layers of label . After the label is packaged into the P router , the top-level LDP label is popped up due to the PHP mechanism . Then the label packet is transmitted to PE2 , and PE2 pops up MP-BGP . The label is restored to the original IPv6 data and then forwarded to CE2 . So how do you perform an accurate calculation of the summary route ? Let's look at an example: Image Route Distinguisher: 1:1 (cisco) Certification Match ipv6 address prefix-list loopb ! IPv6 Address Ipv6 unicast-routing interface Tunnel0 When the network is normal, the data is forced to go ISP1 , ping 100 remote network data to ISP1 The following are the addresses and ports that DHCPv6 might use: Ipv6 prefix-list test seq 5 permit 2001:3::/64 Ipv6 router rip RIPprocess *> 2001:12::/64 [Experiment 1 ] There is a main class route; there is a default route, and the main class route is taken. Image 10.1.13.3 A static route to the host Milne is added to the ROO . The next hop is the E1 port of Kanga . The purpose is to pass the bridge that is often congested. But found that Kanga will be sent to the host Ip default-gateway Support follow RFC 's NBMA on-multipoint topologies and modes of OSPV3 operation. OSPFv3 also supports other CISCO modes, such as point-to-point, etc. Neighbor 4.4.4.4 update-source Loopback0 Mpls ip It is allowed to write multiple next hop IPs , but these IPs must be the interface IP of the directly connected router . Interface Serial0/0 9.9.23.0 is directly connected, FastEthernet0/0 Ip cef Realize network interconnection Ipv6 enable Experimental test Ipv6 access-list x enters acl configuration mode Solution: Modify the routing protocol management distance For example, if you go to a destination and there may be multiple equal-cost paths, you may actually use one of them when forwarding data. Use this command to see which interface is actually used for traffic forwarding. RIPv1 Test phenomenon: can ping through Image Passive-interface configuration Header format Image Then do a simple test: DHCPserver configuration Note that the IPv4 prefix 192.88.99.0/24 here should be published to the routing protocol on the IPv4 Internet. Otherwise this 6to4 relay using the anycast prefix is unreachable in the IPv4 Internet. OR2 , SW1 , and SW2 run OSPF , and OR2 acts as the egress router of the telecommunications, injecting a default route into the OSPF domain. OR1 will be local Match ip address 1 IE6.0 does not support access to IPv6 sites by entering the literal ipv6 address defined by rfc2732 in the address bar . The solution is to access the domain name and modify the hosts file C:/windows/system32/drivers/etc/hosts 90 But on R1 : 1000 – 1FFF R* 0.0.0.0/0 [120/1] via 192.168.12.1, 00:00:03, Serial0/0 OSPFv3 packet Passive-interface Fa0/0 Ipv6 nd dad attempts x Netsh interface ipv6 show ?

The PC will start sending RS with the following message: Access-list 1 permit 100.1.1.0 Network 10.1.23.2 0.0.0.0 area 0 Let's first look at the router: Image Ipv6 ospf 100 area 0 In addition, if the R1 update 1.0.0.0 to R2 , if R1passive out and R2 interconnect interface, invalid after the expiration, R2 on about the 1.0.0.0 route will Pdown , then R2 can still go to 1.0.0.0 , but will not Pass this route to other neighbors, instead sending non-stop messages. At this time, if the interface of R1 is passived , R2 will continue to receive the update, but it will not resume the route immediately, but will enter the holddown timer until the holddown timer expires before accepting the update of the route.
