This article is about troubleshooting MPLS ldp.
Two devices establish direct-attached LDP neighbors:
R2 and R3.r2 's interface Giga 2/0 and R3 interface to establish the LDP's direct-link neighbors.
First, review the LDP's neighbor establishment process:
LDP utility is the UDP/TCP Port 646来 discovers the neighbor's. So in the future troubleshooting, if the two sides can ping, but can not build a neighbor to check whether the port has been sealed
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

High bandwidth, easy to increase service items, low interference, stable voice quality, low cost, good performance/price ratio. These requirements through Netco

The structure of MPLSMultiprotocol Label Switching protocol is described in [1. A label exchange router can be used for Frame Relay switching. Frame relay switches the routing algorithms at the network layer, such as OSPF, IS-IS, and forward data based on these routing algorithms. You do not need to select a specific frame relay path.Frame Relay switching applies to the top-level current tags in the first DLCIData Link Connection Identifier Field of the frame relay data Link layer
R0 creates a tunnel to R1 to enable multicast. It's very simple to scale up and you can see the configuration at first glance. Wvrp has passed.

?? In the network environment, in order to isolate and divide the network, avoid inter-network interference and broadcast storms, define a variety of forms of isolation. There are hardware-based isolation and network protocol isolation, as well as the isolation of subnet segments (subnet masks).?? MPLS and VLAN isolation, based on the software protocol, there is a certain hardware technical support, with these two tags of the packet, before or after t
When there is no peer VRF route, VRF uses MPLS *** to transmit routes to each other ,. After the PE routers at both ends use IGP (PIPE) to build a neighbor, a small pipe (*** V4 cluster) is built in the pipe for ** communication MPLS ** key points: IGP physical links and lo interfaces must be built through BGP large and small water pipes, and reflection must be configured under small water pipes.
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,

Cisco IOS is an interconnected network operating system used on most Cisco system routers and network switches.
When Cisco ios xe processes an IP packet header in an MPLS packet, the CEF module may encounter an error. Attackers can exploit this vulnerabil
In the MPLS/vpn experiment, the configuration of OSPF/r12002 was developed from the basis of the first experiment, so some basic configurations are not mentioned here. The network topology is as follows: first complete the RIP configuration on CE1: Before you configure this, you must delete the previous configuration. If you do not delete the configuration, the problem may occur. CE1: router rip version 2 network 1.0.0.0 network 192.168.1.0 no auto-su
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
