HOW TO MAKE MPLS?16

MPLS LABEL MPLS still need L3 Routing Protocol forpropagate information routing for everymembers MPLS Network to propagate labelinformation Routing Protocol which can be use are : OSPF, IGRP, EIGRP, IS-IS, RIP Label Exchange Protocol which can be useare : LDP, TDP, BGP(VPN), RSVP(MPLS-TE),CR-LDP17

MPLS LDP MPLS Labels are assigned and distributed by the LabelDistribution Protocol (LDP) LDP requirements : IP connectivity – properly configured IP routing (static,OSPF, RIP) between all Router “loopback” IP address that isn’t attached to any realnetwork interface Homogeneous MPLS cloud – all router inside MPLS Cloudmust MPLS enable18

MPLS-based VPN services: L3 MPLS VPN and L2 MPLS VPN. MPLS L2VPN has two modes: Virtual Private LAN Service (VPLS) and Virtual Leased Line (VLL). VLL applies to point-to-point networking scenarios, while VPLS supports point-to-multipoint and multipoint-to-multipoint networking. From users' point of view, the whole MPLS network is

check DHCP server configuration of MikroTik. 5. Check the IP range/subnet of LAN PC client. IP range should be as per prefix/subnet which is received from MikroTik (R-Series will get prefix/subnet from MikroTik router). if LAN IP of the subnet does not match with prefix/subnet, execute the IP and IP renew process in LAN PC to get new IP. 6.

MPLS PW OAM mechanisms are described next, and a brief look at existing layer 2 OAM mechanisms is provided. The article goes on to describe the relationship between end-to-end fault detection and the segment-based OAM mechanisms. MPLS PW An MPLS PW is the mechanism used to carry layer 2 traffic over MPLS. It is a point-to-point

MPLS OAM Overview MPLS OAM technology provides the MPLS network with a defect-detection tool and a defect-rectification mechanism that are independent of any Layer 3 or Layer 2 protocols. The check function of the CR-LSP forwarding plane is implemented through MPLS OAM and protection switching.
