is this router can reserve a 5K IP addresses???
Asked by: Leomared
I googled: 'what is a "5K IP address"' and got nothing, so I'm not sure exactly what you are asking. You can certainly assign an address/subnet to each of the ports that has more than 5,000 ip addresses. For example, I assigned to eth2: this subnet contains more than 65 thousand IP addresses. You can also assign more than one address/subnet to a single interface: I am not sure what the limit is for this, on a per interface basis.
