# GEN AD review of charter-ietf-lisp-04-04

CC @larseggert

## Comments

### "LISP", paragraph 1
```
  - LISP for Traffic Engineering: Specifics on how to do traffic engineering on
  LISP deployments could be useful. For instance, encode in a mapping not only
  the routing locators associated to EIDs, but also an ordered set of
  re-encapsulating tunnel routers (RTRs) used to specify a path.
```
"Could be useful" is a pretty weak motivator. Does anyone want
 to *deploy* this? If not, does it deserve to be a work item?

### "LISP", paragraph 0
```
  - NAT-Traversal: Support for a NAT-traversal solution in deployments where 
LISP
  tunnel endpoints are separated from by a NAT (e.g., LISP mobile node).
```
Stick it into UDP and use existing NAT traversal solutions.
Re-engineering all that does not seem worthwhile.

### "LISP", paragraph 2
```
  - LISP External Connectivity: [RFC6832] defines the Proxy ETR element, to be
  used to connect LISP sites with non-LISP sites. However, LISP deployments 
could
  benefit from more advanced internet-working, for instance by defining
  mechanisms to discover such external connectivity.
```
"Could benefit" is a pretty weak motivator. Does anyone want
 to *deploy* this? If not, does it deserve to be a work item?

### "LISP", paragraph 1
```
  - Mobility: Some LISP deployment scenarios include endpoints that move across
  different LISP xTRs and/or LISP xTRs that are themselves mobile. Support needs
  to be provided to achieve seamless connectivity.
```
"Some deployment scenarios include it" is a pretty weak motivator.
 Does anyone want to *deploy* this? If not, does it deserve to be a work item?
