Bridging w/ multiple interfaces on router

[techracer74]

Hi all, I've goto a need(it's a long story) to connect multiple interfaces to the same subnet. In addition to that, I need to have mutiple subnets per interface available on different interfaces.

i've got Briging configued w/ BVI's and I know I need to assign each interface a bridge group that corresponds to the BVI but how do I assign multiple ip's to a BVI or multiple BVI's to an interface.

Here is what I've got so far:

bridge irb

interface FastEthernet3/0
no ip address
no ip route-cache
no ip mroute-cache
duplex full
bridge-group 100
!
interface FastEthernet4/0
no ip address
no ip route-cache
no ip mroute-cache
duplex full
bridge-group 100

bridge-group 100 route ip
bridge-group 100 protocol ieee
bridge-group 110 route ip
bridge-group 110 protocol ieee
bridge-group 120 route ip
bridge-group 120 protocol ieee

interface BVI100
ip address 10.0.100.1 255.255.254.0
no ip redirects
!
interface BVI110
ip address 10.0.155.1 255.255.255.0
no ip redirects
!
interface BVI120
ip address 10.0.188.1 255.255.255.0
no ip redirects

So can I get multiple interfaces on the same subnet and have multiple subnets on those interfaces at the same time?



Thanks

I know you can assign multiple IP's to an interface with the "secondary" command:

config term
!
interface x/y
ip address 192.168.100.1 255.255.255.0
ip address 192.168.200.1 255.255.255.0 secondary
!
end

As for you getting multiple interfaces on the same subnet I guess I'd have to understand why before I can take a shot at that.
