Keep trunk vlan-assignement in sync with that
and never try to change to avoid problems.
So design your MST instances well;
or stay on Cisco pvst+ with only Cisco switches.

According to the install guide, they can be hot-plugged:

what's an "internap"?

Yes it is safe, but
"no ip virtual-reassembly"
is the best thing you can do, on every interface,
and look form time to time and after reloads weather
Even a 3COM 4200G is called a "layer 3 switch"
(but it's very limited :

8 IP interfaces

Most SFP's (esp. Older one for "low" speed) are fixed frequency,

The crypto-work gets done on the CPU in software,

3845 does not support EHWIC .
ISR(-1) maximum H-WIC, never E-H-WIC.
The build-in ethernet Ports are sufficient to overload that box.
Use a NM-FE[12] to get an dedicated FastEthernet-management port.
Also keep in mind that most ethernet-WICs

You have random /32 more specific host-routes,

Or are the ip's those found as ospf router-id ?

On the lower-price end,
the 3845 has 1200 as maximum recommended number of l2tp tunnels or sessions;
(cisco application note l2tp support for the cisco 800, 1800, 2800, 3800
integrated service routers )
or a 7206VXR with NPEg1

You need some RAM...
The (first) image in FLASH will be loaded started and uncompresses itself.
It reads the config file and, after configuring some of the interfaces,
loads the indicated IOS thru tftp into RAM to uncompress and start it.
So you need RAM for two IOS's unziped...
or a smaller,
No,
boot system does not copy to flash,
it loads file to RAM amd starts it.

Sorry,
but I do not see the difference beetween IPv4 and IPv6 Behaviour here.
As far as i remember you put the LAN-Interface vlan1
and the radio-(sub-)interface into the same bridge-group
and configure the IPv4 (or Ipv6) on the bvi interface
to emulate the normal behaviour of
32 matches
