Very strange netstat -rna output

[Dave]

Hello,
 I'm having a problem on a server of mine that is acting as a bridge,
that whenever I download from the server itself it's very slow. From
machines going through it's bridge there are no problems.

When looking for what could be the cause, I had a look at my routing
table and saw the following --

10.10.10.1       0.12.da.44.e4.0    UHLW        2        0 bridge   1200
10.10.10.2       0.14.c2.60.85.75   UHLW        1       87 bridge   1110
10.10.10.7       0.17.35.13.60.10   UHLW        1      373    lo0
10.10.10.30      0.25.90.1.60.83    UHLW        2        0 bridge   1110

As you can see the second column which usually shows a MCA is showing
some rather strange output? What could be the cause of this?

Thanks
Dave
