Re: [LARTC] Htb on trunked line

Yah, A and C on different ip networks and also different vlan.

It's only example, in the real test i use zebra with a lot of vlan
interfaces and connect to some cisco switch.

And discover that some networks in different vlan can't reach, when i try to
see unreachable networks
using arp, i found uncomplete arp from it.

Until now i don't know why some vlans works fine but the others not.. :(

I think it's because arp, may be need to wait for long time before arp get
complete.
I try this just for half an hour.
