MPLS default MTU is 1500, do not make any changes, I ping full package does not fragment, why can pass! It adds MPLS information altogether is 1504 bytes, how can transmit? Here is my reply: It has been verified, what you need to do is to study your network topology again, if you have a ready-made environment, put your detailed topology map, as well as the configuration of each device sent to me, I can he

BGP/MPLSVPN Concept 1: VRF One of the security measures of BGP/MPLSVPN is routing isolation and information isolation. It is implemented through the VPN route Forwarding (VPNRouting Forwarding: VRF) Table and LSP in MPLS. On a PE router, there are multiple BGP/MPLSVPN concepts 1: VRF tables, which correspond to one or more sub-interfaces on the PE router, used to store the route information of the VPN to which these subinterfaces belong. Generally, t

Recently, I have been reading mpls vpn, but I have never understood the differences between the two RD and RT parameters in VRF. By searching materials on the Internet for repeated reading and thinking, I finally understood it. The following uses a more understandable metaphor for sharing. For example, if you receive an invitation letter, you need to go to a high-end office building to attend the meeting. Because of the strict security requirements,

VPN clients can be provided Internet access by forwarding the traffic of the VPN user to the ISP's Internet network management. Implemented by creating a static route in the VRF of the PE router and specifying the next hop in the global routing

1. Interconnection between different VRF: (Integration of intranet and external network) The topic finally found a positive solution in the book. There's always a question around me and some friends, if two vrf (companies) have access to each

We break down the Multi-Protocol Label exchange technology into several major elements, hoping to help you understand the working principles of this technology. To facilitate understanding, we will use an interesting analogy to describe how the

Multilayer Switching (MLS) is an Ethernet-based route exchange technology that provides a layer-3 Switch with an existing router. This article includes IP-only MLS; ipx mls and multicast MLS are out of the scope of this article. A traditional router typically performs two main functions: rewrites the Media Access Contr

the VLAN to a specified port group. Only hosts connected to these ports can dynamically add VLANs, the MAC address of the host on other ports cannot be added to the VLAN even if the MAC address is matched in the database.8. Configure InterVLAN routing:Communication between VLANs requires a router, which is completed by the RSM module in 5505,Therefore, the RSM module must be configured to configure routes between VLANs. The configuration is as follows:Console> (enable) session mod/num // slot o

We talked about QoS commands, Metro Ethernet, WRED, network management, network security, and so on:MQC is a modular QoS;Use MQC to implement QoS: class-map --> policy-map --> service-policy;Enable QoS on a multi-layer switch: mls qos;Border of configuration trust: mls qos trust (cos | dscp | ip predencel) trusts the priority information carried by the inbound traffic;Several observed command

single industry to a network service platform in multiple industries As shown in figure 1, the original IP private network in industry a is transformed and upgraded to become a network service platform, providing network services for multiple industries at the same time. There are similar demands in Politics and Law networks and e-government affairs networks. How to provide a logically isolated, secure, and reliable virtual IP private network for various industries has become a technical proble

switch connects to the aggregation switch through multi-link bundling. On the one hand, it can completely avoid second-layer loops and make full use of the uplink bandwidth of the access layer. Note that STP should be enabled even in L2 Networks without loops to prevent errors in device configuration and physical link maintenance. At the same time, although the network does not have a loop, STP may still affect the L2 network across multiple data centers. For example, when the network topology

1. Should I use MPLS (Multiprotocol label switching) VPN? For many business network needs, the answer is absolutely certain. The transition to MPLS is well underway. Take a look at this data. MPLS VPN has been gobbling up the market for frame Relay for years, according to data from market research firm Vertical Systems Group. In the next 18 months, the number o

At present, PE routers are widely used. They are one type of VPN routers. So I have studied the explanations and principles of PE routers and will share them with you here, I hope it will be useful to you. VPNVirtual Private Network (VPNVirtual Private Network) is a virtual Private Network based on public networks. It uses tunneling, encryption, and other technologies to provide users with a sense of direct connection to the Private LAN. Introduction to MPLS
