[c-nsp] Add 2nd Trunk

[Ahmed Hilmy]

Thanks Tom for your kind email.
I got your points.
our customers will never accept any interruption !!!
i can move some VLANs from 1st trunk to 2nd one, in this case should i care
about loop ?  i think it will not happen , each trunk will carry different
VLANs and at swtich side configure 2nd trunk ?
