Absrtact: Broadband IP metropolitan Area network, routing planning and design is the core link. In the beginning of the network, must be integrated planning. According to the construction of the metropolitan area Network, the routing strategy based on Bgp/mpls VPN is adopted, which is proved to be feasible by practice. Key words: BGP MPLS VPN IP Routing strategy 1 Broadband metropolitan Area Network overv

, which is intercepted by the owner proxy and encapsulated through a IPv6-in-IPv6) tunnel to the current transfer address of the mobile node. When a mobile node receives a packet encapsulated by a IPv6-in-IPv6, it sends a binding update message. If the entry LER receives the Binding Update message from the mobile node, it initiates the LSP operation between the entry LER and the exit LER. The IP-in-IP tunneling technology of the original Mobile IP protocol has a high header overhead and heavy lo

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

In the HUB-AND-SPOKE environment of mpls vpn, for the sake of security AND cost, the branches are not interconnected, AND the access between the branches must go through the firewall of the headquarters, both the security effect and the cost are saved.The experiment topology is as follows:Due to the existence of the downstream bits and domain tags in the anti-ring mechanism of OSPF, the route may not be received in the outbound VRF of r6. therefore, t

MPLS (Multi-propocol Label Switching) is a Multi-Protocol Label exchange.MPLS is a third-generation network architecture and a new generation of IP High-Speed Backbone Network Exchange Standard, proposed by IETF (Internet Engineering Task Force, Internet Engineering Task Group, led by Cisco, ascend, 3Com, and other network equipment manufacturers.MPLS is an integrated IP over ATM technology. It combines routing functions on Frame Relay and ATM switch,

1 Introduction 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

?? 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.

What is the premise of using MPLS traffic engineering for CISCO? or MPLS te configuration logic: Cisco IOS software version that supports MPLS traffic engineering. The network needs to start CEF. The link state protocol used as IGP OSPF or Is-is. Only these two protocols can support TE. (OSPF provides a class tenth LSA to propagate related TE information). Th

VPN instance changes, the changed PE device should take the initiative to send the BGP refresh packet to refresh the VPN route, and use the new RT attribute to filter the route. Different from RD, We can configure multiple RT attributes for a VPN instance, and the RT attributes are released in the extended group attributes of the bgp update message. The format is similar to that of common group attributes. When a route carries multiple extended group attributes and RT attributes at the same tim
