Hi, this is a very basic question at least I think it is, apologies for being so green in advance.
I’m trying to wrap my head around MPLS and have built a small lab. I understand how provider routers label switch packets and how provider edges use VRF instances and their distinguishers and targets to address each other. Per the Juniper examples I have LDP and RSVP enabled on all the transit interfaces along with MPLS and obviously the correct interface families (MPLS) attached to the same transit interfaces. I then per the doc built a label switched path something like. set protocol MPLS label-switched-path r1-r4 to 10.0.0.4 ;destination loopback of R4 which is acting as a PE I have an equal return to 1 built as well I also have a bandwidth reservation defined set protocol MPLS label-switched-path R1-R4 bandwidth 10M and a reverse reservation as well As I understand you build these relationships between the loopbacks. My question is how does this relate to the VPN VRF entries on the provider edges? Is this a global value that reserves 10 megabits between R1 and R4? What if you want to reserve 10 megabits and 5 megabits between R1-R4-VRF1 <> R4-r1-vrf1 and r1-r4-vrf2 <> r4-r1-vrf2 where you have two matching sets of VRFs on the same PE pairs. Is this possible or do I have the function of RSVP confused? Again sorry for the n00by question I’m just trying to figure out how all the pieces fit together. If anyone has any reference pointers that might be a good start that explains this I would be interested as well. The Juniper documentation is quite good but I can’t figure this out via searching so far. Any pointers would be most appreciated.
