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,
In the traffic engineering of MPLS TE, it is divided into the following aspects:
1, the release of information
2, the calculation and establishment of the path
3, traffic forwarding in the tunnel.
So here to understand the path calculation and build, first of all to understand how SPF is working, and then see what is CSPF (constrained SPF). In order to establish the calculation of the path is a good understanding. In detail, why do you want to lea

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.
