CEF Load sharing-Two T-1's

Unanswered Question

I have set up per packet load sharing to a new office we opened up, two T-1's connecting the two sites. It looks as if the paths do not show as equal, they are both 1.544 private lines. The out put of show adjacency detail shows 1 line at 22 and one line at 16. Any help?

I'm not certain the 22 and 16 have anything to do with the packet counts over the interfaces, or the percentages used, etc?


The packet counts do look off, but are those numbers there from when you were doing per source/destination pair load sharing? I would clear the counters, or make a note of where they are now, and see how it comes out later. Of course, I wouldn't use per packet load sharing in the first place, but that's another issue....
