The principle of the protection of TE is already mentioned. Today's focus is to explain how the Frr-fast-reroute in Te Protection is configured, and how to look at the state. Before introducing the configuration, it is important to note that FRR fast rerouting is a protection mechanism. Imagine if the R2 to R6 is an ordinary IGP network. After the middle link down, what is the situation? It should be the first problem the router sends the LSA through the other interface and then reddening to

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

, 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

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

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.
