Hi Sandip, Thank you for the reply. Link which you have mentioned talks on MPLS LSR Mib, however I want to know about the metrics in general which are used to monitor the over all MPLS. For eg, the link above have LSR mib which descrive insegment , outsegment and crossconnect and related traffic parameter. Howver seeing those parameter directly will not help us to get any conclusive output. Hence I want to know what are the parameter/metrics which can be monitored to know the details on MPLS Devices or Network or Components (VPN, LSR etc) thanks

Hi Any one can help me to know various metrics which are must or needed to monitor different parameters on MPLS Network. Few parameters which I have are : 1. LSP Utilization : To know the over all bandwidth used. 2. LSP Error : It would be great if i have some real time monitored metrics . thanks,

Hi My question is who and how LFIB get populated at each LERs (Edge Routers), Do it is same at each edge router ?

Hi Nagendra, Thank you for reply. If I understood correctly, then there will be only one Path (LSP) for each destination , if LDP alone is used to forwarding packets. And does this can be called as Core MPLS LSP ? What are the other protocols which are similar to LDP ? Helping to generate Path automatically without giving any inputs. Thanks

Hi Vignesh, As it is mention Core MPLS, it understood that it do not use any latest protocol to manage the path or Traffic Engineering. What I am not sure is how these LSP are created (if created manually) or it is just plain LDP Protocol which distribute the labels across each Hop (LSR) and based on which the packets moves to next destination. I am bit confuse on the above concept, when we have pre defined protocols LDP, which help to generate Label for moving the packet to its destination, why we have to create / how we create LSP . How LSP overtake the labels defined by LDP at each Hop ?

Hi , Could any one explain me what is Core MPLS LSP (It seems that it do not support any TE, LDP or other protocol) ? Thanks

Hi, Recently I came across new term known as "Enterprise VPN" . I am aware of L3VPN, but not sure about new Enterprise VPN. Could any one help me to understand 1. What is Enterprise VPN. 2. How different it is from L3VPN 3. And How to check if the current PE have Enterprise VPN or L3VPN ? Thanks,

Hi Shivlu, Isn't this gives the interface name of PE which are bind to specific VRF (VPN). And there may be more than one interfaces allocated to single CE. Is there any way to get this information from SNMP Protocol.

Hi Harold, This is another question I want to ask you. How do I find out from PE, the number of CE connected along with their Ipaddress. I am looking to get overall topology of MPLS network. Regards

Hi Harold, Thank you for your response. I was looking to know the command or SNMP OID or any other way, to identify P or PE router. For example, if you have two ipaddress, and you need to know which one is P and which one is PE, which command or SNMP query you like to execute to find it out. Regards

Hello, I would like to know how to differentiate if CE and PE are seprate devices (Routers) or it is same. I have seen in many deployment, the CE is combined with PE and kept at customer place. It may be since there is not many Services Configured (other customer) in that PE ? How to distinguish the both pattern. Also how to identified via SNMP if the given router is P or PE may be both ? Regards, Ayush

Thank you Imran . I have tried looking all the MIB's to find the appropriate OIDs which can get me 1. LSP/Tunnel configured on P routers. (Please correct me, the LSP are configured in Provider routers, not in PE) 2. Interfaces which are assocuated with each VPN (VRF) in PE. If you can help me to find these, it will be great help to me. Thanks, Ayush

I have got answer to some of the question I have asked. 1. Since the Label Forwarding table is created in each Hop, which have the label entries for all incoming and respective outgoing packets. So the label is across all the routers, and to know which hop it need to select, it is decided by RSVP dynamic protocol. RSVP is the one whcih establlish the LSP and maintain it. 2. LSP are unidirectional and are create from source to destinaltion. If there is another secondary LSP is created as a backup, which comes in effect, when ever there is issue in primary LSP. the fastReroute will swtich the traffic to backup LSP.

Hi Imran, As per my understanding, the LDP protocol such as RSVP or BGP generate the the label and distribute it to other routers. Hence the database gets updated at each Router about the mapping between incoming label and the respective outgoing label. This has create a way (path) to take the incoming packet to final destinaltion with the help of label, created during LDP session created between two router. Hence the path is availble, and below are my questions: 1. when the path is been derived with the help of Label, why we need to create LSP. 2. Does this path is know as promary path, and with LSP we need to create secondry/backup path 3. Label are associated with each interface, hence when a VPN service is created in PE, we need it to associated with all the interfaces configured with ldp ? Thanks, Ayush
