Hi everybody and a happy new year, :-)

got a connection problem i can't resolve.

Here's the config and cabeling. R1 connected to SW1 and SW1 connected
over a trunk to SW2. SW2 is then having
a port in VLAN10 which is then connected by a crossover cable to SW1,
which has the port configured as a routed interface.

R1(fa0/0,10.0.0.1) -- (fa0/1, VLAN10)SW1(fa0/13)--ISL
trunk--(fa0/13)SW2(fa0/14,VLAN10)---(fa0/14,10.0.0.2)SW1

Now i can't reach 10.0.0.2 from R1.

If i ping from SW1 i can see icmp echo requests reach R1 but the answer
does not find it's way back.

Is it possible to debug trunk traffic to see what's going over the trunk?

Frank
