Cisco routing w/ HP DTC/ AFCP etc...

[Michael Nesteriak]

I am changing our old brouters over to new Cisco's. The problem I am having is
the lack of the lack of HP's AFCP routing capability. I dug up an ARP PROBE
(assigned to an interface) command for the Cisco. Any comments/ suggestions
regarding this? We cut over next Saturday and this MUST be smooth.

Any advice would be greatly appreciated.

I think we have fixed this.
I HIGHLY recommend doing this on a downed interface. We experienced complete
interface shutdowns after attempting this. DON'T DO IT LIVE!!

Cisco IOS 12.0 (6) commands...

configure terminal
bridge crb
bridge 1 protocol ieee
bridge 1 route ip

Then apply the bridge-group 1 to BOTH sides of the bridged interfaces.

This takes everything on the segments and bridges it except ip (it routes ip).
Great way to find out what is on your WAN.

TO LOCK IT DOWN TO ONLY THE DTC EQUIPMENT...
configure terminal
access-list 200 permit 0xf8f8 0x0000
access-list 200 permit 0xfcfc 0x0000

Now apply the access-list to the interface where the DTC's come into...
configure terminal
int eth x\x
bridge-group 1 input-lsap-list 200

This turns the bridge group access-list into a filter for only the protocol
type required by the DTC's. Do this on both sides of the WAN link.

Much thanks to Scott M. at Cisco for coming up with this!
