Basic VPLS Architecture, Full Mesh

Comparison of VPLS and h-VPLS VPLS (Virtual Private LAN Service) and h-VPLS (Hierarhical VPLS) has some common and different properties. So they have different aadvantages and disadvantages.In this article, we will focus on the comparison of these two concepts. The most important different between VPLS and h-VPLS is in the interface between the CE (Customer […]

Traffic Flow without ECMP, alcatel-lucent service routers, SR 7750

ECMP (Equal Cost Multi Path) If the total IGP cost to a destination are same for two path, these paths are called Equal Cost Multi Path. Normally if there are two path that have same IGP cost, in Alcatel-Lucent Service Routers, lower interface wins and the traffic goes through it. Traffic Flow Without ECMP Think […]

LDP configuration example topology, alcatel-lucent service routers, SR 7750

LDP Configuration on Alcatel-Lucent Service Routers To do an LDP configuration example, we will use the below basic topology. Here, we will configure these two routers to become an LDP peer and establish an LSP session. LDP Configuration Example Topology Configuration on Router A A:RouterA>config>router # interface “to_RouterB” address port 1/1/1 exit interface “system” […]

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 (Resource 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 […]
