The RRs have physical connections and establish BGP peer relationships. In the case where one of the RRs fails, the client still has an alternate connection. Four types of AS_PATH path attributes Encapsulation protocol Note also that, because the R4 and R5 for the federal EBGP neighbor relationship, so there are also TTL is 1 problems, if they use the loopback interface to establish BGP relationship, it needs to use to neighbor 5.5.5.5 ebgp-multihop 3 command. The thing we have to do is very simple. These subnets are continuous. It is enough to pick out the first two or three network numbers to calculate: On CISCO IOS , interface x interface mode: Route-map test permit 20 router bgp 200 Update behavior BPDU format and operation The other values ​​of DSAP and SSAP are pure IEEE802.3 frames. If you only want to detect the reachability of some next-hop devices, you can configure different route-map serial numbers to selectively use this feature (in the same route-map ). 32768 When the topology changes, the spanning tree protocol can detect these changes and automatically adjust the interface status in time to adapt to network topology changes and achieve link redundancy. Switchport Configuration and implementation Neighbor IBGP_peers update-source loopback0 neighbor IBGP_peers password cisco Router ospf 100 BGP filter R2 No synchronization no auto-summary Next Hop 200 ? ? port-security does not support etherchannel the port-channel interfaces MAC sublayer R2 re-advertises the A route, then according to the preemptive rule, R3 will ignore the R1 update about the A route. At the same time, due to the deployment of two-way re-release, R3 will further re-publish the learned A- route back to process 1 . -------------- The certificate contains the password information when it is verified using plain text.

Define set action Multilink Multilink-group interface R 1.1.1.0/24 is possibly down, ------------------ 00:B0:64:04:09:99 When a router connects through a multi-access medium such as Ethernet, a dynamic mechanism is needed to discover each other, such as ARP . ARP can map Layer 2 addresses to IP . If it is a frame relay multipoint link, the adjacency relationship can be learned by using an address resolution protocol, a mapping table, and the like. 100 i Bgp deterministic-med Example 1 : Major Points RIPv1 29 Configuring DAI logging Due to the inherent lag of network equipment,ccnp tshoot exam tips, there is a propagation delay in the switching network. For the above reasons, topology changes can occur at different times and in different network segments in the switched network. If the Layer 2 interface switches directly from the block state of the spanning tree to the forwarding state, a temporary data loop may occur. To alleviate this problem, the port should wait for new topology information to propagate to the entire switching network before starting to forward the data frame.
