we have cisco 878 series router,we try to make an icmp packet from vlan 1 and the client is the same vlan,when we try this so there was no icmp packet generated from router.I see the arp of client but i couldnt ping from router.What could be the problem.
Could be any number of problems. Is the client directly connected? Are there any ACLs blocking ICMP? Is the router sourcing the ICMP from the correct interface. Does the client you are trying to ping have the correct settings (default gateway etc).
Perhaps you can provide some more information and configuration (minus sensitive lines such as passwords).
Yes,it can.I can send telnet from router to the clients tcp port that it listens.It's ok,But whe i try to send an icmp from router so client didnt reply me.But i can send an icmp behind the router.I suppose that router not forwards self generated icmp packets,i opened all related debugs ( arp,icmp etc.)but i didnt see any arp req response.
No there should be no reason the ICMP from the router is blocked. Can you clarify when you say "But I can send ICMP behind the router" exactly what you mean. Could it be an issue with the clients firewall?
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
