Hi Colin,
Consider this as an example:
interface tunnel 88
description "Tunnel to anchor"
tunnel mode gre 88
tunnel source 172.16.32.1
tunnel destination 192.168.15.210
trusted
tunnel vlan 888
!
My question is this command: tunnel mode gre <num> - is this <num> a 16-bit protocol type of the payload packet as per the GRE packet header in RFC 2784 ???
In the example above, I use tunnel mode gre 88, and the config works. I changed it to some other number, says 14, it also works.
ArubaOS 6.4.4.0 continues to support L2 GRE tunnel type zero, but it is recommended to use a non-zero tunnel type. So what is the real use of this <num> as in tunnel mode gre <num>?
Kind regards
Kenneth
