vMX or MX - sampling on logical interface with encapsulation bridge domain

‎02-19-2018 04:07 PM

Hi all,

Does somebody have a clue if on vMX or MX204, flow sampling is possible on a logical interface with encapsulation bridge-domain? 

I'm working on a L2gateway bridging two vlans using vxlan and need to have some visibility of traffic passing this L2 vxlan tunnel, this is the solution:

VlanA-----[vMX]---------{IP Network}------[vMX]--------VlanB

 

It seems it's only possible to apply ipv4/ipv6 sampling templates under family inet, but not on bride domain interfaces, and of course, if I sample on the WAN side, i only get VXLAN's UDP traffic.

 

Is there a way to achive sampling on bridge domain? I haven't found much information of this on MX routers.

 

REally appreciate any help.

Hi,

IMO, sampling is not supported for bridge-domain. There is an option for "family vpls" but I doubt it will work. You can probably use port-mirroring instead?

 

Here are some links for your reference:

Thanks

Hope this helps
