ArubaOS 6.3.x -> 6.4.x upgrade / GRE Tunnel-Type Requirements

Hi

 

releasenotes say 

GRE Tunnel-Type Requirements
This section describes the important points to remember when configuring an L2 GRE tunnel with respect to
tunnel-type:
l ArubaOS 6.4.4.0 continues to support L2 GRE tunnel type zero, but it is recommended to use a non-zero
tunnel type.
l If both L2 and L3 tunnels are configured between end point devices, you must use a non-zero tunnel type
for L2 GRE tunnels.

im using simple MC3400 with campus AP105 and few RAP3-WN with basic plain RAP connection. how is there concerning regarding info from releasenotes regarding the L2 GRE tunnel type zero , im stuck in information how far this concern my setup so far. 

 

the RAP3wn are not zero-touch connected, they are connected with static user/pw/PSK like a classic RAP setup as i learned in 2010. im using CPSec internally for the campus APs and the VPN-services are just straight configured only for the RAPs , there are no L2TP users/IPSEC VPN users connecting direectly to the MC3400.

 

someone can tell me regarding zero-tunnel in which case this affects perhaps to us ? 

 

thanks

Link to release notes?

 

Just guessing that this only refers to site to site GRE tunnels, NOT GRE tunnels created by access points.

hi cjoseph,

 

well the copy/paste info is just from releasenotes 6.4.x , it's everywhere mentioned in 6.4.x releasenotes and i just dont know if this concerns my setup at all . 

 

do you really want link to releasenotes , i dont think this helps as copy/paste is the same written there.

It only relates to site to site GRE deployments.

Re: ArubaOS 6.3.x -> 6.4.x upgrade / GRE Tunnel-Type Requirements

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
