Experts,
out of the well-known values for ip options:
X@r4# set ip-options ?
Possible completions:
<range> Range of values
[ Open a set of values
any Any IP option
loose-source-route Loose source route
route-record Route record
router-alert Router alert
security Security
stream-id Stream ID
strict-source-route Strict source route
timestamp Timestamp
I can only think of:
- RSVP using router-alert
- ICMP using route-record, timestamp
But I can not think of any other use of any other IP option.
Considering the security hazard that they imply, I am therefore thinking
to drop them.
Is any other ip options used by: ospf, isis, bgp, ldp, igmp, pim, bfd?
Thanks,
Luca.
