Cisco Router ARP Configuration
Posted on 2003-03-13
I am trying to configure our Cisco 3640 router to associate with a new IP address on it's FastEthernet0/0 interface. It's presently configured to be 22.214.171.124, 226, 227, 228 and 229. I would like to add 230 as well, but I do not understand how to do it correctly. Here is a copy of the interface configs:
ip address 126.96.36.199 255.255.255.224
no ip directed-broadcast
If I simply add an ARP command to the configuration, it seems to work, but not well. By that I mean that certain TCP based services do not function through the router. If I do a Show ARP
Protocol Address Age (min) Hardware Addr Type Interface
Internet 188.8.131.52 41 0002.b325.d349 ARPA FastEthernet0/0
Internet 184.108.40.206 - 0002.b325.d349 ARPA
Internet 220.127.116.11 3 0002.b325.d349 ARPA FastEthernet0/0
Internet 18.104.22.168 41 0002.b325.d349 ARPA FastEthernet0/0
Internet 22.214.171.124 - 0004.9ac1.80c1 ARPA FastEthernet0/0
this is what's presented.
126.96.36.199 was added through an ARP statement in the config by me. The others were added by somebody else, in a different manner which I do not know. How might these other addresses been entered, and how would I enter more in the same way? Thanks.
