I would like to know what does that debug message means: As221 L2F: OUT UDP FS Fail

I have an AS5300 and, when I activate debug vpdn l2x-errors it appears very often a message this similar:

As221 L2F: OUT UDP FS Fail

Re: I would like to know what does that debug message means: As2

Generally speaking the message is not

a cause for concern. This message

indicates that an L2F packet was not

fast switched. I'm not sure if you

are doing VPDN or MMPPP, but you should

ensure that fast switching ("ip route-

cache") is enabled on all your interfaces.

It could also be a message indicating the

first packet of a connection is not

being fast switched, which is also expected.
