GARP Broadcasts for proxyarp Feature?

SchmuFoo — Thu, 02 Feb 2017 21:16:00 GMT

Hello Community,

for an ongoing migration I'm already using the proxyarp feature [1] on an MLAG Core.

I wondering if it is possible that the L3-Switch sends an GARP via Broadcast, when proxyarp is used for an /32 address?

Cheers

I am wondering that proxy-arp work on your EXOS environment ?!

At my installation with X670-G2 (V22.6) it does NOT work ... i have to re-build in my lab ...

Jepp with that in place I could do an Host by Host Migration from an (interconnected) old Core to an Extreme Core, with overlapping Networks in both worlds.

I dont remember the details, but you can directly ask your colleague Robert W. who was my Teamleader during that time 
