[c-nsp] Juniper pinging 7206 via 3750 and 3550, 7206 'forgets' MAC address

[Alexander Koch]

Folks,

this is strange. A Juniper pings a 7206, and the pings just
stops at one point. One the Juniper the MAC address is still
there, on the Cisco it says Incomplete after the ping stops.
Whenever I clear the ARP entry on the Juniper, it works again.

Any clues? JunOS 6.3R3, 3750 has 12.2(25)SEA, the 3550 has
12.1(22)EA6, the Cisco 7206 has c7200-ik9o3s-mz.124-1.bin.

I am lost, the 3750 has the MAC addresses in the table just
fine, and any clues are definitely welcome. It is strange
when a continuous ping is running and the 7206 then says
'Incomplete'... the 7206 is running at 30 to 50% load in
'show proc cpu'.

Regards,
Alexander
