Hunt,
Do a 'debug ip rip' and you'll get to see all the interactions. Also 'debug
ip route' will let you see what comes into your routing table. This is the
best way to find out, and also the best way to confirm what you have is
working especially in the lab where you have to test something 3 different
ways.

Hello Group,
I'm trying to find out what happens when there are multiple distribute-lists
applied w/ distance vector Routing Protocols.
For "distribute-list <x> in", if global distribute lists & interface
distribute lists are used, then both must allow the network for it to be
allowed into the Routing Table:
access-list 3 permit 3.3.3.3 0.0.0.0
access-list 4 deny 3.0.0.0 0.255.255.255
access-list 4 permit any
distribute-list 3 <in> <Ethernet 0>
distribute-list 4 <in>
Even the interface distribute-list allows the 3.3.3.3 host route to be
coming in via the Ethernet 0 interface, but the global distribute-list denys
it. Is it true that the 3.3.3.3 will be deny??
For "distribute-list <x> out", the global distribute lists, interface
distribute lists & redistribution distribute lists are applied
independently.
e.g. access-list 3 permit 2.0.0.0 0.255.255.255
access-list 4 permit 3.0.0.0 0.255.255.255
access-list 5 permit any
distribute-list 3 out serial 0
distribute-list 4 out
distribute-list 5 out rip
...so in this case, network 2.x.x.x is allowed to go out via Serial 0,
network 3.x.x.x is allowed to go out via all interfaces (including Serial 0
Interface) + any 3.x.x.x network originated from any external protocol are
allowed to come in to the Routing table, while all networks are allowed to
go out to all RIP neighbors + any RIP networks are allowed to come in to the
Routing Table.
Any help will be greatly appreciated.
Best Regards,
H.
