- Long Syntax:
- GRE.001 Too many encapsulations, dropping packet
- Description:

- Long Syntax:
- GRE.002 Optional flag/s are set in first octet of GRE header of incoming - packet. These options are not supported.
- Description:
- We are receiving a packet whose GRE Header indicates that it
supports GRE optional features like Strict Source Routing, Key,
Sequence Number, Checksum etc. We don't support any of these
features yet and hence put out a warning message to that effect

- Cause:
- This is because the remote end is possibly a non-OpenROUTE equipment
that has implemented these optional fields for GRE.
- Action:
- Reconsider implementing these optional fields in the GRE header(?)
