I have recently moved my WCCP redirection at my remote locations from my 3750 switch stack to the WAN routers. I have noticed strange statistics when issuing the "show interface" command. Please take a look at the output below.
bos14rtrwn01#show int mult 1
Multilink1 is up, line protocol is up
Hardware is multilink group interface

Internet address is x.x.x.x/30
MTU 1500 bytes, BW 3072 Kbit, DLY 100000 usec,
reliability 255/255, txload 10/255, rxload 239/255
Encapsulation PPP, LCP Open, multilink Open
Listen: CDPCP
Open: IPCP, loopback not set
Keepalive set (10 sec)
DTR is pulsed for 2 seconds on reset

Obviously this is a 3Mb circuit but my input rate indicates 6.5Mb. Something is off here. I have checked the Bug toolkit but did not find anything.
Anyone else having this issue?

I'm guessing you are using the gre-return (negotiated return) feature on your WAEs?
If so, you are probably seeing CSCsk44513 which causes your incoming interface counters to incorrectly increment. There isn't any current workaround, however it shouldn't affect anything outside the counters incorrectly incrementing.
Hope that helps,

Thanks Dan. I am using negotiated return on the WAEs and this is the bug I was looking for. Looks like an upgrade of the image will clear the issue.
