Is there a limit to the number of subinterfaces configured (ie. number of vlans) when doing inter vlan routing using router-on-a-stick?

    I dug up an article online that said 4096.

    "IDB (interface Descriptor Blocks) An Interface Descriptor Block (IDB) is a special control structure internal to the Cisco IOS software that contains information such as the IP address, interface state, and packet statistics. Cisco IOS software maintains one IDB for each interface present on a platform and one IDB for each subinterface." Therefore, the number of IDB's constitutes the number of possible interfaces on a platform.

    There is no place like 127.0.0.1 BUT 209.62.5.3 is my 127.0.0.1 away from 127.0.0.1!
