BGP routing black hole and full IBGP connection

Networking requirements:1. AS65000 boundary network segment release: RT1 and RT2 re-release direct connection route to OSPF (metric 1000 type 1)2. BGP Configuration Requirements:No synchronizationNo auto-summary IBGP uses LOOPBACK to establish a neighbor, and the next hop points to itself3. RT1 and RT2 publish a summary route of AS65000 to BGP: 10.0.0.0/16 and 10.3.0.0/16.4. RT5 publishes a summary route fo

BGP routing load balancing fault case

BGP routing load balancing fault caseNetwork Architecture 1. Topology: the actual network structure is simplified considering the privacy of the company's network and a clearer description of fault phenomena. 2. network planning and data Configuration Overview: ◆ ASR9K establishes IBGP neighbor relationships with two n7ks Based on the interconnected addresses respectively; ◆ ASR9K is connected to the Cisco

A test report of BGP Route-map Policy Routing advertisements

Today, we gave a client a test report based on Route-map to filter through different routes to different end-to-end Cross-domain neighbors. The function point is very small, but for the junior students want to help. BGP is actually a very powerful routing protocol for routing filtering. CCIE is also the focus of the

Iv. Verify the key issues of default routes in BGP Route summary protocol (with the extended ACL matching research process)

Key Issues 1) How does an ACL match route entries with the same subnet and different masks? How do I match entries with the same mask and different subnets? 2) Why does a summary route cause a tumble of BGP peers? 3) Why does the acl fail to match the route entry when attribite-map is used? 4) How to Use advertise-map, suppress-map, unsuppress-map, attribute-map, and route-map routing diagrams? Instance. 5)

Protocol forest 03 IP race (IP, ARP, Rip, and BGP protocols)

generate the most reasonable path (merge ). (The basic logic of RIP is: if A is 6 away from B and I am 1 Away From A, the distance from A to B is 7) For technical reasons (looping hops), rip considers that IP addresses over 15 cannot arrive. Therefore, rip is more used in the Internet (such as the entire China Telecom Network ). Such an internet part often belongs to the same ISP or has the same management organization, so it is called an autonomous system (as, autonomous system ). Hosts and

BGP Route Protocol planning

In the network structure, we have been paying attention to their deployment and optimization. As the network pressure increases, we have put forward higher requirements for some hardware and protocols. Now, we will focus on the deployment of BGP routing protocols. In general, the BGP routing

BGP Routing Reflector Overview

exists in a route, the RR will not create a new originator_id. (2) When other BGP speaker receive this route, they will compare the received originator_id and the local Router ID, if two IDs are the same, BGP speaker ignores this route and does not process it. The Originator_id property guarantees that the route does not loop between the reflector and the client/non client. Cluster_list is a 4 8-bit op

Huawei BGP Routing Principles

BGP routing is optimal, in the absence of filtering, there are two conditions related: Next hop can be reached, synchronous shutdown. If these two conditions are not met, the routing is not optimal.BGP Routing principle: If the next hop of this route is unreachable, this route is ignored Preferred-valnue value

The problems that arise: A) R1 has a 7.7.7.0/24 route on it, but Ping 7.7.7.7 is not reached. (R7 same) Now view the R1 routing table R7#sh IP route B 1.1.1.0 [20/0] via 5.5.5.5, 00:02:54/To save space incomplete display It can be seen that R7 learned the route of the R1, from the surface to see the experiment is perfect, for the purpose, but then the problem arises, make a test, on the R7 ping R1 R7#ping 1.1.1.1 Type escape sequence to abort.
