Hi and Thanks for getting back to me.
I'm migrating from Arris C3 CMTSs to the uBR7246 platform.
On a simplified level, our current network config has Business User Cable Modems using one Config file while Residential User use another Config file.
For the Arris C3 CMTS, I just specify which Cable SubInterface to attach CPE traffic TO in the Modem Config File, and I have this Cable SubInterface in the same Bridge-group as a FastEthernet SubInterface which has an associated VLAN Tag.
This results in the Traffic Passing through the CMTS and appearing on the other end as Tagged Traffic.
I need to be able to Separate Business Customer Traffic from Residential Customer Traffic and in addition to this, I do have a few Customers that would use PPPoE in their own Private VLAN.
What you suggest above might work for the PPPoE Customers, but are you saying that that I can't separate the other customer traffic into Business and Residential VLANs?
There are various 'Bridge' commands in the uBR.
If not for Bridging Interfaces for Traffic, what do they do???
<1-255> Bridge Group number for Bridging.
cmf Constrained multicast flooding
crb Concurrent routing and bridging
irb Integrated routing and bridging
mac-address-table MAC-address table configuration commands
Router(config)#bridge 1 ?
acquire Dynamically learn new, unconfigured stations
address Block or forward a particular Ethernet address
aging-time Set forwarding entry aging time
bitswap-layer3-addresses Bitswap embedded layer 3 MAC adddresses
bridge Specify a protocol to be bridged in this bridge group
domain Establish multiple bridging domains
forward-time Set forwarding delay time
hello-time Set interval between HELLOs
lat-service-filtering Perform LAT service filtering
max-age Maximum allowed message age of received Hello BPDUs
priority Set bridge priority
protocol Specify spanning tree protocol
route Specify a protocol to be routed in this bridge group
subscriber-policy Subscriber group bridging
I'm using IOS v12.2(33)SCE.
Many Thanks for your time,
first I have to say that I am not an uBR professional, I only configured two uBRs, one 7246 and one 10012. Both had a more or less straightforward configuration.
The first thing that comes in my mind are two Bundle interfaces, one for Business and one for Residential customers.
I tried to bridge the interfaces facing the CMs and I got an error message, later I read that the 7246 does not support it.
Maybe you can bridge between Ethernet interface, but you don't need that.
