Label Distribution And Traffic Flow

Label Distribution After LDP session establishment, labels are distributed from the Tail-End router to the Head-End router for each prefix. This process occurs at the opposite direction of the data plane. At the data plane the traffic flow goes form the Head-End to the Tail-End. But label distribution process is done at the opposite direction. […]

MPLS Label Distribution Protocol, LDP LDP (Label Distribution Protocol) is one of the two label exchange protocols of MPLS. The other is RSVP (Research Reservation Protocol). And there is also one more, Cisco specific protocol, TDP(Tag Distribution protocol). In this article, we will talk abbout the LDP. And the examples will be also for Alcatel-Lucent […]

RSVP Configuration Example Topology, Strict Hops

RSVP-TE Alcatel-Lucent Configuration Prerequisites and Configuring RSVP-TE – Configure IGP. – Enable MPLS context. – Enable RSVP context. – Configure interfaces for MPLS ( automatically RSVP). Let’s check these step sone by one. Configuring IGP (Routing Protocol) is required for routing between the nodes. This is the first required step. Before RSVP-TE configuration, be sure […]

RSVP PATH Messages, RSVP Label Request Messages

RSVP-TE (Resource Reservation Protocol-Traffic Engineering) RSVP-TE(Resource Reservation Protocol-Traffic Engineering) is the enhanced RSVP for MPLS. RSVP-TE is not a real routing protocol, but it works with routing protocols. For RSVP-TE, bidirectional flow is required. To provide this, there must be two RSVP sessions. Because RSVP-TE is unidirectional. RSVP-TE brings some benefits to MPLS. These benefits […]

Export and Import Policy and Prefix Aggregation with LDP LDP and Export Policy By default ALU only distribute a label only for its system addresses. To distribute additional other local prefixes, “export policy” is used. You can find an “export-policy” example below: A:>config router policy-options begin prefix-list “interface1” prefix 10.0.0.6/24 exit policy-statement “LDP_Export_Policy1” entry 10 […]
