Each LAN-segment (>1000 sites) terminates on a router with its own
on this interface are configured two IP addresses from different
subnets. Its not a cisco, but on a cisco it will be configured as
described from you:
> ip address 10.10.1.1 255.255.255.248
> ip address 10.11.1.1 255.255.255.248 secondary
On this router the dhcp-relay is configured for two different
Limitation in this release is the definition of only one GI Address for
So the GI IP for the relayed packets is in this case 10.10.1.1 for both
The router / dhcp relay has a routed connection to both dhcp-server.
Both servers will receive the discover from 10.10.1.1. Server A has a
Server B has only 10.11.1.1/29.
Both servers can't use the same pools due different routing issues.
Thats the reason why my intention was to use the option 82 for the
