Weird FA config...

[Auger282]

Hi... Just to give you a little background I'm just a local tech looking at a corp. Cisco "dude's" router config.

Our network is kind of a bish-bosh of Hub and spoke switches... We have 2 networks active on the same backbone... two gateways, one on each of the 2 FA ports on our 2600. So in short the two lines coming from the two FA ports go into the same switch stack (no vlans) which are intern connected to the "hub and spoke" switch system.

here is the current config for both FA ports

!
interface FastEthernet0/0
ip address XXX.XXX.10.1 255.255.255.0
speed 100
full-duplex
ipx network 431
no mop enabled
bridge-group 1
!
interface FastEthernet0/1
ip address XXX.XXX.16.1 255.255.252.0
duplex auto
speed auto
ipx network 432
!


We do run a Novell server that runs IP, IPX, and IPX over netbeui.... I think the network # on the server is 432.. I'm not exactly what hes doing with the 431..


I'm just looking for comments on how you think this should/could be done better

I appreciate your help!

Oh.. I also wanted to tell you my initial reaction (being CCNA.. but on the bottom of the food chain) .. I'm not about to tell this guy what to do.. but its my network too.. *sigh*

..I was thinking something like...

!
interface FastEthernet0/0
duplex auto
speed auto
ipx network 432
no mop enabled
bridge-group 1
!
interface FastEthernet0/0.1
ip address XXX.XXX.10.1 255.255.255.0
!
interface FastEthernet0/0.2
ip address XXX.XXX.16.1 255.255.252.0
!
interface FastEthernet0/1
duplex auto
speed auto
ipx network 432
no mop enabled
bridge-group 1
!
interface FastEthernet0/1.1
ip address XXX.XXX.10.1 255.255.255.0
!
interface FastEthernet0/1.2
ip address XXX.XXX.16.1 255.255.252.0
!



I donno..

The current configuration that you are using is because the previous network admin is running two different network segments on the same broadcast domain. This will work, but is not optimal.

Generally what you would do, is setup VLANs to create more broadcast domains. Then you would add that router to both vlans, by either using one interface (w/ subinterfaces) or two physcial interfaces.

Generally speaking though, your network should work fine (as long as it's not too big). It isn't a good idea if starting from scratch, but many small networks do this to save money on buying managed switches.
