I have a tidbit to add.
Multicast is not supported on secondary networks. So you can't support
protocols that use multicast on the secondary network such as WCCP or H323.
Or at least you'll have to configure unicast connectivity for things like
OSPF or EIGRP.

You really do not have a lot of choice in the matter. The subinterface
configuration can not be use unless you are running ISL encapsulation
(vlans) or a point-multipoint type network on the interface. If you try to
use the sub-interface setup without these the router will give you an error.

They do different things. In large part, secondaries are a rather
ugly hack to deal with an a
One disadvantage of using secondary interfaces is that Cisco has indicated
secondary interface support will disappear in future IOS releases, in favour
of supporting subinterface configurations.

Hi Louie
I just want to clear one thing.
I thought that subinterface was created as a solution
for split horizon, so without subinterface configured,
split horizon should be on.
Could you verify what you said "if you
hi Brian.
I have a quick question from what you mentioned
regarding multipoint subinterface that I have always
been wondering about.
You mentioned, "Point to multipoint" and it can
communicate with many routers within that same
subnet."
Let's say there is a router in a headquarter, and 2
routers i
you can define a subinterface to be "multipoint" instead of "
point-to-point". then instead of
using "frame-relay interface-dlci x"
use multiple "frame-relay map" commands under that subinterface definition.
apply an IP address to the subinterface, and the IP addresses on the other
side of the PV
Austin,
This response is in a bit more detail than the others but I think it's
worth it.
As another option you can also specify multiple dlci's and still use the
"frame-relay interface-dlci xxx" -- once for each dlci. This will allow
you to continue to use dynamic mapping vice static map stat
you can define a subinterface to be "point-to-multipoint". then instead of
using "frame-relay interface-dlci x"
use multiple "frame-relay map" commands under that subinterface definition.

I am configuring 2 sub-interfaces on the router. One subinterface for the
connection to router1 and 1 subinterface for the connection to router2 and
router3. I will not be configuring subinterfaces on router1, router2 and
router3.
Hope this gives you some more information and it is a Frame Relay

sure. You can do it for ethernet interface or serial interfaces. You can
configure the secondary ip address on that interface.

can you be more specific? I am going to make the assumption you are
talking
Here are some examples with Frame Relay (watch for word wrap) :
