CL: somewhere around IOS ver 12.0, the behaviour changed. Inverse arp is no longer disabled when a frame relay map is entered. CL: you may also run into the famous frame relay map to 0.0.0.0 problem, the cure for which is to enter the no frame inverse etc, save, then reload > > 2. Is it necessary to enter the command "no arp frame-relay" after "no > frame-relay inverse-arp"? And what exactly are the differences with these two > as I'm quite unfamiliar witeh the "no arp frame-relay command"? > CL: no help here. the command master index on the doc CD gives this explaination: Usage Guidelines Unlike most commands that have multiple arguments, the arp command has arguments that are not mutually exclusive. Each command enables or disables a specific type of ARP. For example, if you enter the arp arpa command followed by the arp probe command, the Cisco IOS software would send three packets (two for probe and one for arpa) each time it needed to discover a MAC address. The arp probe command allows the software to use the Probe protocol (in addition to ARP) whenever it attempts to resolve an IEEE-802.3 or Ethernet local data-link address. The subset of Probe that performs address resolution is called Virtual Address Request and Reply. Using Probe, the Cisco IOS software can communicate transparently with Hewlett Packard IEEE-802.3 hosts that use this type of data encapsulation. ---------------------------------------------------------------------------- ---- Note Cisco support for HP Probe proxy support changed as of Release 8.3(2) and subsequent software releases. The no arp probe command is now the default. All interfaces that will use Probe must now be explicitly configured for the arp probe command. ---------------------------------------------------------------------------- ---- Given a network protocol address (IP address), the arp frame-relay command determines the corresponding hardware address, which would be a data-link connection identifier (DLCI) for Frame Relay. CL: looks like the no arp frame-relay is an alternative to the no frame-relay inverse-arp command, but I've been known to be wrong. ;-> > Thanks.
