Steve,
Just take 10.77.0.1 255.255.0.0 off FastEthernet0/0.1 and put it on
FastEthernet0/0.77, and you should be good to go.
Thanks,
Adam

Yes, I knew that was a problem, but wasn't sure which way to go.
Is there any way to do this by changing the router instead? The 10.77.0.0/16
is supposed to be part of the 77 vlan. I'm hoping to be able to do this
remotely (the site has limited access hours). The router is the nearer
device and the switch is behind it (from the central site's point of view).
Thanks!

Steven,
Right now you have 10.77.0.0/16 on vlan 1 on the router but on vlan 77 on
the switch.
If you want the switch to use an IP address from the 10.77.0.0/16 block, you
have to include vlan 1 as the native vlan on the 3550, and put the
10.77.0.10 address on vlan 1 rather than vlan 77.
Thanks,
Adam

Subject: [c-nsp] Question on 802.1q trunks and L2TPv3
I've got a 3640 router that's connected to a 3550 switch. The trunking is
set up as dynamic desirable, and I need to change it to be a dot1q trunk.
I'm having a little trouble getting that done. I tried doing a:
switchport trunk encapsulation dot1q
switchport mode trunk
and the switch became unreachable. Do I need to add something like:
switchport trunk native vlan 77
?
Parts of the config are included below...
Thanks!
