Inverse ARP

Question:

Please help me Cisco 2951 out here. Where does the Inverse ARP run - in the frame-relay switch or in the attached router?

Also, when static mapping is configured, does it simply turn off the Inverse ARP or does it just overwrite the dynamic mapping?

Answer:

First, the router sends the inverse arp when it has an address and a dlci to go out on. When there is a static mapping for a certain address/dlci combo, inverse arp is disabled on the dlci. Here's a good explanation of the other ways this can be configured:Cisco 2921 price
