GRE tunnels in MX series

[merylu13]

Hi, I need to know how many GRE tunnels are supported in the MX family, I find that this devices can support until JUNOS release 10 and after, but I cant find the maximun to this tunnels.

There is no limitation on the amount of GRE tunnels on the MX-series. When using MPC linecards (based on Trio chipset) the tunneling can be performed in-line on the Trio chip and you don't require a dedicated ASIC anymore. 

The limitation is on throughput, the chipset offers 30Gbps of throughput linerate. The tunneling is done in hardware and therefore is not limited, except to the chip limits.

Thanks for your answer, but do you tell me in with site (paper, KB), I can support this answer, I need to support this with any document or link with my client.

Thanks for your help.

Can help me with a document that support that only apply the Troughput when we can create GRE tunnels?? I need to suppor this with a KB, Release note or some specific document

• Mentions the "inline" nature of the GRE service on the Trio chipset. (pg 2 under trio chipset)

• Describes the need to limit the services by bandwidth, not by number of tunnels/services (pg 7-8)

• Describes a testing environment with 1000 GRE tunnels
