Netgear M6100 backup port feature?
Hi guys. This is my first time writing in this forum, so please excuse me if I'm writing this at the wrong place. Anyway, my client has a Netgear M6100 chasis with a 24x10G blade attached. Right ...
Thank you Dane, Laurent and Carl for your responses. :)
I have discussed the possibilities of using various forms of routing protocols and/or VRRP with my clients. Unfortunately, it is technically not possible for both gateways to be up at the same time, as they both would have the exact same IP address.. >_<
Apparently, under the Netgear there would be another router as per below illustration:
For some reason, we could only use two (yes, only two..) IP addresses between the three of them.. somehow our client only have one spare /30 segment available.. >_< Traffic should go up relative to the Switch, from GW3 to either GW1 or GW2. So naturally GW1 and GW2 would have the same IP address shared between them.. >_<
That's why I've been trying to find an alternative method like using Link Dependency, as Laurent pointed out. If push comes to shove, I might have to ask our client to replace the M6100 with the newer M4300..
At any rate, thank you guys for the responses so far. Feel free to suggest something out of the box that you think might help solve this problem. :smileywink:

Hi McKwack
Trying to understand your problem better:
So, both GW1 and GW2 have same IP address shared between them on their LAN side each time?
Sometimes I've seen pairs of gateways (managed by Service Providers) running VRRP between them natively and obviously sharing same virtual LAN IP address.
Are we in this configuration? If yes, it shouldn't be a problem to connect both simultaneously to M6100 switch, in same L2 broadcast domain (VLAN).
Would you happen to have GW1 and GW2 configuration files with their LAN configuration?
We will try to advise based on that.
Out of the box, I don't think we want to "replace" M6100 capable chassis switch by stackable M4300's for that only issue.
If above proposal not applicable, we can insert one M4300 switch in between M6100 and GW1/GW2, so that Link Dependency feature can be used on that new M4300 layer, on ports connecting to GW1 and GW2.
