Dear Sir!
I've point-to-point link between two routers with such configuration:
R1---R2

hostname R1

If these are the configs you are running two different versions of RIP.
Router 2501A is running version 2 while the others are version 1.
Did you mean to do this?
What is the reason you need to redistribute the connected interfaces on the
bottom 2 routers? Rip will do this for you. Let the

RFC's are great, but have to look also at how Cisco IOS implements the rfc.
PIM DR's use IGMP to query the hosts too !!

Do you mean that in IOS if a router is running PIM and is a DR, it will
query even if it sees IGMP query messages from another router with lower ip

Thomas,
EIGRP is an Interior (I)GRP unlike BGP which is an
Exterior Routing Protocol. BGP Autonomous systems need
the AS number to distinguish one from another. EIGRP
on the other hand would normally be running without
any knowledge of other systems EIGRP protocol. It will
normally not interact
The AS number in EIGRP is really more of a routing participation group
identifier. All routers with the same ID will participate in EIGRP. It
has no real relation to the Autonomous System used in BGP and for good
reason. BGP is an exterior routing protocol. As such, you have a group
of ASes

FAQ,
Here it is !! That was my confusion, because it seems that this capability
was added in order to query IGMP version 1 hosts. With IGMP version 2 it
seems you do not need it. But what happen then if you have both IGMP v2 and
PIM DR's ?? Do they both query the hosts ?
Any Multicast expert right
Is there an IDS signature that can help you recognize it on the PIX? That
maybe the easiest way to do it.

Whenever you type a command on the active unit it's being replicated to the
