The router bit indicates whether it is a router or not. If it is 0 , the announcer cannot route data. The way through the announcer The cost of the route. Route tag: A tag that distinguishes between internal routing protocol routes and external routing protocol routes. Switchport access vlan 20 interface vlan 10 OSPFv3 the RouterID or 32bits , if not on the router IPv4 address, in OSPFv3 manually specify the required process Next Hop 1 Use RS to request RA Based on agreement Prot 2001:1111::1/128 Ipv6 unicast-routing Image Neighbor 2001::1 activate ::FFFF: 4.4.4.4 Ipv6 address 2001:12::2/64 interface Serial0/1 !! OSPFv3 between PE-CE Generally, it is 60-240 seconds longer than the invalid timer . If this time also expires, the routing entry is completely deleted. Cisco default 60s (note than invalidtimer multi- 60s ), RFC default 120s ! IGRP/EIGRP 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 , For example, in this example, we want to inject, the metrics of the two routes 192.168.1.0 and 192.168.2.0 become 2 hops, and 3.0 becomes 120 The problem that the static route associated with the outgoing interface is re-released. Ipv6 route 2002::/16 tunnel1 !! When accessing the remote 6to4 network locally , take the tunnel When the network is normal, the data is forced to go ISP1 , ping 100 remote network data to ISP1 X Update behavior *Mar Ipv6 address 2001:12::1/64 ! The MPLS Domain consists of three routers: PE1 , P , and PE2 . The IGP protocol running in the domain is OSPF , and the process ID is 100 . Each of the three routers announces its own loopback port into Core 's OSPF . The address of Loopback is xxxx/32 , and x is the router number, such as PE1 is 2.2.2.2 , P is 3.3.3.3 ,ccna premium dumps, and PE2 is 4.4.4.4 . Improve Routers can learn routing entries in a variety of ways: static manual configuration, various dynamic routing protocols, and more. When the router learns two routes to the same destination from two different ways, the router compares the AD values ​​of the two routes , that is, the management distance, preferably the route with a small AD value. If the AD values ​​are equal, for example, the same routing protocol, the metric value is further compared . Of course, this also involves the working mechanism problem of different routing protocols, which is specifically discussed for different routing protocols. As shown in the following figure, R3 and R1 run the RIP protocol, and R3 establishes adjacency relationship with R2 through OSPF . Therefore, R3 learns the route to the destination 1.1.1.0/24 from RIP and OSPF . The two routes use R1 and R2 as the next hop respectively. Then R3 finally chooses the OSPF route to be loaded into the routing table, which is to use R2 as the actual destination.
