IP Source-Track

Very simple scenario:

r1----sw1-----r2

r1 fa0/0 ip and r2 fa0/0 ips in vlan 1

are ping able...

eigrp running...

added loopbacks on R1

Theses loopbakcs are pingable from r5..

Then the fun....

(ON R1) ip source-track 11.1.1.1 (IP Address on in loop1)

pings then fail from r5 to r1 on this loopback.

if i do a no ip source-track 11.1.1.1 the pings wont come back.

If i make a new loopback with a differnt subnet and apply ip source-track, i get the same result. Am i doing something wrong?'

CORRECTION: the pings do come back after removing the command it just takes a while.
