I am stumped. I thought that you need to know the number of VLANs configured on each switch in order to know how many subinterfaces I need. Any help greatly appreciated.

Yes, that's my take on it as well: the Router uses only one physical interface on which the IP Address is configured. The ROAS configuration then creates one subinterface for each VLAN that you want the trunk link to support. But I'm unsure of what BennyTheMan is saying about the answer he's been given in the post.No longer an active member -
OptionsBennyTheMan Member Posts: 76 ■■■□□□□□□□Sorry for not being clear. I choose 2, based on the 2 switches but the correct answer is 5. I totally didn't read the question carefully. Now I see that the question states there are 5 vlans. Duh!
Thanks,
