Two sets of juniper data cores to prevent loop occurrence by configuring Mc-lag
I. BACKGROUND
There are two sets of data core switches deployed in two different network rooms, the current state is a single-mode fiber three-layer network interconnection, but the business unit put forward a new network requirements, to build three network segments, gateway to enable the core switch in a-block room, C block room also to use these three network segments, fortunately in the same park, Can be deployed two single-mode fiber, through a two-layer network to achieve, if two rooms in a remote place can only be achieved through the VPLS way.
Second, network topology

The A-block core switch is the core switch of the two Juniper EX9200 series, which consists of the vrrp,c core of the two Juniper
EX9200 series of core switches composed of VRRP, the newly added three network segments of the gateway configuration on the A-block core, if not configured Mc-lag, four cores formed a loop, through the configuration Mc-lag, to implement the anti-ring mechanism. on The aggregation layer, two core switches are connected to each other, and there is also a loop, where you can use Juniper's own anti-ring configuration RTG instead of spanning tree protocol. RTG is easier to use than Mc-lag, but can only be used when one end is a single device, so the RTG configuration cannot be used for anti-ring between the two sets of cores.
