I have three networks currently on my bundle interface:
10.60.0.0/22 - CM network
20.30.40.0/24 - CPE
10.144.0.0/18 - MTA
Here is the interface:
interface Bundle1
ip address 10.144.63.254 255.255.192.0 secondary
ip address 20.30.40.254 255.255.255.0 secondary
ip address 10.60.3.254 255.255.252.0
ip helper-address 10.231.102.104
ip helper-address 10.231.102.204
cable arp filter request-send 3 2
cable arp filter reply-accept 3 2
no cable arp
cable dhcp-giaddr policy
arp timeout 36000
end
What happens is since the 10.60 is the primary IP on the bundle, the CM dhcp goes to this=working cm. Next is the 20.30.40.0/24 subnet. Since it is the next ip block, the cpe dhcp goes to it, and does work. Ok, tricky bit. Under this current configuration, I need to place 20.30.40.0/24 and 10.144.0.0/18 into a DHCP super scope to get the 10.144 mta chip to get an IP address. Unfortunately when I do this, it is not allowing my DDNS/DHCP process to work because of DNS views (i.e. 20. is an external view and 10. is an internal view). So my desired result is to have this all work in some form of seperate networks so that I can get each subnet on it's own GIADDR and not use superscopes in my dhcp configuration so that DDNS will work.
Anyone have any suggestions?
