VPLS and Split-Horizon for multi links - routers NOKIA(Alcatel-Lucent) 7750SR & SAS7210-T(M).

 

Services VPLS we can be connecting by multi links between some routers, by directly links and MPLS links. In this reason,  we can use STP and SPLIT-HORIZON technology.

We can use path cost STP on dedicated link that has to be the backup link.

SPLIT-HORIZON can avoid creating loop when links overbooked.

Example is shown below.
