2nd Packet always dropped in Traceroute

[Cerdito]

Hi there,

I have two routers directly connected by Ethernet.

Management IPs:

Router1 - 10.37.44.161/25
Router2 - 10.37.44.142/25

When I ping between them I lose about 1 packet in 10,000. Not too bad, but when I do a traceroute from either one to the other the 2nd packet is always dropped:

Router1#sh ip ro 10.37.44.142

Routing entry for 10.37.44.128/25
Known via "connected", distance 0, metric 0 (connected, via interface)
Redistributing via ospf 100
Routing Descriptor Blocks:
* directly connected, via Vlan1
Route metric is 0, traffic share count is 1

Router1#trace 10.37.44.142

Type escape sequence to abort.
Tracing the route to 10.37.44.142

1 10.37.44.142 4 msec * 0 msec

---------------------------------------------------------------------------

Router2#sh ip ro 10.37.44.161

Routing entry for 10.37.44.128/25
Known via "connected", distance 0, metric 0 (connected, via interface)
Redistributing via ospf 100
Routing Descriptor Blocks:
* directly connected, via Vlan1
Route metric is 0, traffic share count is 1

Router2#trace 10.37.44.161

Type escape sequence to abort.

1 10.37.44.161 0 msec * 0 msec


Any suggestions why this is?

I can't recall why this happens but it is normal behavior and nothing to worry about.
