Title: RE: KickStart
The Null0 route is automatically entered when you aggregate routes.
The supernet is routed to null0 and when the router receives a packet
addressed to that supernet... the longest-match rule is applied. If a
more specific route does not exist, the packet is dropped.

If I don't get some mail from this list soon, I may have to join the
OTHER
groupstudy list just so I have some lunchtime reading. 200 messages a
day for
someone going through mailing list DTs is a fix. Heck, I have been
reading
everything I get from this list before the microwave is done!
I have a few questions from things that I am working on that I would
like to
pose:
I was wiping out my configs from a BGP session when I noticed that I
had a
route to Null0 in my router. Under what circumstances would you see
this
route?
In OSPF, what is exactly the rule on authentication? Is it simply all
interfaces attached to the individual network, as well as any router
ospf area
x auth commands in the area? Or does every interface in , say area 0,
have to
have the same passwords and authentication methods on ALL interfaces
in area
0? I have built these & tried a few different methods, but it seems
to work
many times when I think it should be broken.
What is the cisco(LAB) definition of a VPN? Everybody and their
brother seems
to have their own definition regarding tunnels, encryption, pptp,
vpdn, leased
line, etc.
BTW, I hope I am not violating anything here, but I heard a rumour
that both
BGP AND OSPF will be on the lab. :-)
These are some areas that I am working on - Anyone wish to discuss? I
would
like to at least get enough reading to make it through the Lean
Quisine that
the wife sends for lunch as well as the vending machine cupcakes that
I follow
it with.
