We have a need to have multiple IP networks recognized by an ethernet interface on a cisco router. Referring to the manual, cisco states that you may have multiple secondary addresses on the ip address subcommand line. We have tried this and it doesn't seem to work. For instance, ip address 128.196.250.1 255.255.255.0 128.196.252.1 128.196.254.1 results in no apparent change in the operation of the interace other than changing the primary address. A show interface command does not show the secondary addresses, nor does the show interface command. We must be doing something wrong. Any ideas?

Hello Ted, To specify more than one interface, use the 'ip address secondary' command as follows: ip address 128.196.250.1 255.255.255.0 ip address 128.196.252.1 255.255.255.0 secondary ip address 128.196.254.1 255.255.255.0 secondary Thanks, Allan Leinwand cisco Systems leinwand@cisco.com

Hello Ted, You need to use a variant of the 'ip address' command with the 'secondary' option specified. It works as follows: ip address 128.196.250.1 255.255.255.0 ip address 128.196.252.1 255.255.255.0 secondary ip address 128.196.254.1 255.255.255.0 secondary Thanks, Allan Leinwand cisco Systems leinwand@cisco.com
