[nsp] Latency on the directly connected

Has anyone seen latency like this on a directly connected link? When I
source the directly connected interface, I see no packet loss. If the
testing is just from the router, I see packet loss.

Connected/static routes only. The source ip adddress is a secondary ip
address on my main (ISP) interface. The interface snapshot is below. Any
hints would be helpful. Thanks in advance.

Router#ping ip
Target IP address: 192.168.1.2
Source address or interface: 192.168.1.1
Sending 100, 100-byte ICMP Echos to 192.168.1.2, timeout is 2 seconds:
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Success rate is 100 percent (100/100), round-trip min/avg/max = 1/2/4 ms

Router#ping ip
Target IP address: 192.168.1.2
Sending 100, 100-byte ICMP Echos to 192.168.1.2, timeout is 2 seconds:

Success rate is 100 percent (100/100), round-trip min/avg/max = 80/105/132
