How to block bpdu packets in an ASR 9k Link

There are some situations when we really need to block bpdu from going over a Backbone router.
Some examples are:
- When extending a L2 segmento to another datacenter
- When interconnecting 2 CORE infrastrutures with diferent vlan IDs.

Obviously, this is done using best pratices such as having a single connection between these points using aggregation (LACP) port-channels between the sites or MPLS.


So, the solution to apply to a specific port is to build a l2 acl like this one:
ethernet-services access-list block-invalid-frames

  10 deny any 0180.c200.0000 0000.0000.000f
  20 deny any host 0180.c200.0010
  30 deny any host 0100.0c00.0000
  40 deny any host 0100.0ccc.cccc
  50 deny any host 0100.0ccc.cccd
  60 deny any host 0100.0ccd.cdce
  70 permit any any
