both the cisco and vanguard are in same subnet connected in the same switch(no vlans)(factory settings thts it in the switch).

problem here is i m able to ping vanguard ip from cisco but not the viceversa.

on both the cisco router and switch ports where both the rotuers r connected.def g/w in vanguard tried both ethernet ip of vanguard and cisco eth ip.

any help on this wil b helpful

Hello,

Since you are receiving ARP, which confirms that communication is happening, then I would do a couple of things next.

Perhaps something is blocking the ICMP traffic. Since you are unable to ping the Cisco IP from teh Vangard, perhaps there is an access list or something like that being played.

Another thing you can try is just bypass ICMP all together. Try to telnet to the Cisco and see if you get through.

At least that would confirm that only ICMP is affected, and not all layer 3 traffic.
