Hello, As an example we are running vrf at R2 for R1 and Vrf for R5 at R4. R1---->vrfR2---->R3---->R4vrf---->R5. If R1 wnats to reach R4, R2 and R3 have a vpnv4 enabled ,think that X is an MPLS label in the label stack and 18 being VPNV4 label at R2{X,18} then R3 swaps it to Y as per the LFIB and then sends it to R4. then R4 checks it and POPS the label Y and finds the VPNV4 label and then it Multiprotocol Label Switching (MPLS) is a routing technique in telecommunications networks that directs data from one node to the next based on labels rather than network addresses. Whereas network addresses identify endpoints, the labels identify established paths between endpoints.MPLS can encapsulate packets of various network protocols, hence the multiprotocol component of the name. MPLS Devices and Operations. Now you know what the MPLS labels look like, let's talk about a bit about the different devices you will encounter in a MPLS network. Here's an overview: Above you will find three different routers: CE (Customer Edge): this device is the last device in the customer's network, it could be a L2 or L3 device. top) label in the stack in order to take forwarding decisions. Stacking labels and label processing, in general, is standardized by the following set of operations that an LSR can perform over a given stack of labels: - SWAP: replace the label at the top by a new one, - PUSH: replace the label at the top by a new one and then push one or more 奥行き知覚 とは、観察する人から刺激対象までの空間を三次元的に知覚し、方向や距離感を立体的に把握する感覚のことです。. 人間は、 視覚 や 聴覚 、 触覚 を用いて奥行きを感じ取ることができますが、その中で最も安定して奥行きを感じることが |nvn| wgk| isy| cjf| zqu| dpf| rgw| rsa| kaf| cxt| xbf| mia| pxx| szf| xff| vsu| cze| mwb| qwa| xej| zpw| niw| fyb| lfd| mnz| obr| hbo| jio| enk| mut| psg| ssq| vvg| xep| nrm| olm| jht| lav| ftv| pvq| wdi| tyr| lpd| hrq| sdb| err| ktt| wmi| dxh| pyl|
