Cisco IOS-XE Fails ip add 241.1.1.1 255.255.255.0 Not a valid host address - 241.1.1.1 ip route 241.0.0.0 255.0.0.0 10.10.10.1 %Invalid destination prefix XR-OS : fails Can take the IP on a interface, but cant route it IOS fails we used up all the reserved ip blocks including the 169.254 and the benchmark, and the 100.64/10 and ofcourse the RFC1918. Lots of apps don't do ipv6 so we are finding interim solution...i guess that's karma since doing so sort of anti-facilitating the use of ipv6 :) On Wed, Jun 17, 2015 at 5:12 PM, Ca By <cb.list6 () gmail com> wrote:

Just for NATTING on Cisco gears...most things, including most cisco gear, will not forward those Class E packets or accept Class E as a valid address If you have success, please report it to the list.
