[rbak-nsp] SEOS and Clips IP-pool

[Dariusz Siedlecki]

Hello,

I have one question.

We have Redback SE 400 with Redback Networks SmartEdge OS Version 
SEOS-6.2.1.2-Release.

We have a lot of CLIPS interfaces with dhcp server interface option and 
separate DHCP pool configuration for each CLIPS
Configuration is running with Radius. If some one get reject from 
radius, it gets IP from dhcp pool.

Let's say that configuration looks like bellow:


  interface clips-NO1 multibind
   ip address 10.10.1.193/26
   ip address 10.63.130.193/26 secondary
   dhcp server interface
!
  interface clips-NO2 multibind
   ip address 10.10.2.1/25
   ip address 10.167.5.1/25 secondary
   dhcp server interface

  subnet 10.10.1.192/26
      range 10.10.1.241 10.10.1.249
      option subnet-mask 255.255.255.192
      option router 10.10.1.193

  subnet 10.10.2.0/26
      range 10.10.2.241 10.10.2.249
      option subnet-mask 255.255.255.192
      option router 10.10.2.1


Redback if it run out of free pool in one CLIPS, it will borrow IP 
address from next CLIPS pool - in this case - client in VLAN connected 
to clips-NO1 will get address from clips-NO2 free dhcp pool.

Is any way to prevent dhcp server from this behaviour ?
For me the  best option is to do not give any IP address if pool in one 
CLIPS interface is full.

Any tips ?

Best regards.
