Access-list 200

[morgans]

I am having problems trying to limit Bridged traffic to protocol types 6001-4.

The two routers connected by a WAN are using CRB, with the following bits of config pertinent to this query

access-list 200 permit 0x6001 0x0000

access-list 200 permit 0x6002 0x0000

access-list 200 permit 0x6003 0x0000

access-list 200 permit 0x6004 0x0000

bridge 3 protocol ieee

bridge 3 route ip

bridge 3 route ipx

interface Serial0/0/0.1 point-to-point

bridge-group 3

bridge-group 3 output-type-list 200

Even with this supposedly stopping all bridge traffic (other than the allowed protocols), we are still seeing all other protocol types across the link.

Every access lists has implicit deny with them. So, they will automatically deny any other traffic apart from those permitted ones.

But in your issue, based on your explanations, the performance of the accesslist seems to be quite opposite. To further look into this issue, could you send me the debug output of access-list. Also, complete configuration of the routers.
