I have a MPLS VPN network and on one of the 7200 routers which is one hop away from the edge, I have an MPLS entry which says "Recursive Paths" (see below). What does recursive path means? How is the next hop information found in this case? 133 ...

Hi, In my mpls-forwarding table for a trial MPLS VPN network, I came across a few entries that are missing the outgoing interface and next hop information. I am curious to know how can such entry exist? What is the behavior when a packet with label ...

I am trying to understand the output of 'show mpls forwarding-table detail' command on cisco 7200 routers. For each entry in the MPLS table, I can see a set of 'label stacks'; example below:18 35 10.0.1.1/32 0 Gi1/0 ...

does it mean that we need to look up the new label (i.e. 66) in the MPLS table again? or are you referring to looking something up in the IP table?

Thanks for you example. I understand this case. Now imagine you are in a carrier network with 2 layers of MPLS and a VPN label (a total of 3 labels)I am going to modify your example as follows:R1---->vrfR2---->[R3---->[ R4 ]--->R5]---->R6vrf---->R7...

Hi Mohammad, I think the MPLS entry, regardless of where/how the router is deployed should determine the behavior. Based on the information in this entry, does a incomming packet with labels {X, 18} go out as {X, 120, 35} or just {120, 35}? ThanksPe...

Thanks Sandip. I was wondering what the behavior would be if a packet arrives with let's say labels 100 and 18, with 18 being the top-of-stack label? It technically matches on this entry, right? now what will be the outgoing label(s) look like?
