I apologise if this question has been answered recently but if someone could answer the following question I woul appreciate it. I have recently added some partial IP functionality to primerily support SNMP on our INX bridge product. Of the items which I want to support is ICMP redirect. Testing this feature though is the tough part. We currently have a cisco gateway (I have the gateway system manual but have never done anything with the gateway itself). It is possilble to test ICMP redirect with only one gateway? Just thinking of the problem it could be solved if it were possible to manually insert a bogus entry in the cisco's gateway table. That is the bridge wants to send a (trap message for example) packet to a management station at address x. In the cisco's (routing) table he sees that gateway w (in our case a manually inserted address, non-existant gateway) is the way to get to management station x, and gateway w is on the same net as the cisco. Under normal circumstances the IP spec states that this is a situation where the gateway should send an ICMP redirect message to the datagram originator. If it is possible to add such a static entry into the routing table such a test might be able to be performed using only one gateway. Is the above pipe-dream possible or if not is there some other way that someone knows of testing the ICMP function. Thanks Mike Scanlon scanlon@interlan.interlan.com
