MX250 as IPAM

I would like to have  reservations for all LAN based devices in my network.

 

I have 5 vlans  = 5 subnets

I wish to reserve / static allocation 128 addresses per subnet.

 

In summary  about 600 reservations

 

Does the MX250 have any reservation limitations?

Never heard of a limit, but I've never had to reserve that many either.  The biggest DHCP pool an MX can handle is /19, per vlan, so I don't think 600 reservations over 5 vlans would be too many.

Hi , 

 

I don't think there is any limitation to the reservation limit. Are you planning to run DHCP on the MX ?

 

The only issue I see is : Note that the largest DHCP pool the MX will serve is equivalent in size to a /19 subnet, even on a VLAN configured with a larger subnet

But I hope your 5 vlans are smaller than a /19 🙂
