Hello

May i know if there is any plan to release ccr which has 4 sfp+ ports?

Already exists, CCR1072

that is USD 3K device ... too expensive ...

I am looking for cheaper one around 1k++ USD and just 4 x SFP+ is enough ...

Otherwise I am thiking to use 2x10G setup bonding and create 2 vlans 1 for BGP facing and 1 for Server facing

What do you think?

Are you doing BGP etc? If so 3k is cheap as chips. The other alternative is if you just need layer 2 is to get a layer 2 switch off ebay or such.

IIRC bonding is done on CPU (software), so I wouldn't expect anywhere near 20G performance.

An alternative would be to build your own box with a hypervisor and multiple 10G NICs and use CHR on top of it.
