RSVP (Resource Reservation Protocol) is a signaling protocol that handles bandwidth allocation and true traffic engineering across an MPLS network.

RSVP – fast reroute
1. Intro Fast reroute can dramatically reduce packet loss in the case a primary path fails. Even if you have a secondary path signaled with the standby feature there is still the possibility of many packet drops. This happens because the message for the failed path must still travel back towards the ingress LSR so […]
RSVP – Secondary Paths
1. Intro In the previous example we tested link coloring with multiple LSPs to the same destination, which is not ideal. In this post we will configure Secondary paths. By default, when network failures occur along the path of RSVP signaled LSPs, traffic will be dropped. The ingress LSR continues to send traffic until a […]
RSVP – Link Coloring
1. Intro Administrative groups provide the ability to mark the interfaces with similar characteristics in a common group. Based on these groups you can restrict the LSPs to use a certain path in the network. Marking the interfaces is known as coloring but is actually based on setting the affinity bits on interfaces. Up to […]
RSVP – Basic Config
1. Intro We will use the following test topology for RSVP: For RSVP basic configuration we need to perform the following: 2. RSVP Basic Configuration We we will demonstrate RSVP basic config on R1 router (all other routers already configured): External Resouces:
