GRE tunnel configuration

[dushanraman]

Hi folks,

Could anyone provide some insight on how to configure a GRE tunnel between 2 x 7705 nodes.

I was only able to find configs to intergrate SDP to use GRE tunnel, but nothing of how to create a GRE tunnel.

Would be great if someone could provide an example or just point out what needs to be done.

Thank you.

Hi,

I think in Nokia Router to create GRE tunnel, we just use that you mention above.

Thank You

Hi Thanks for that will try to implement it and see how it goes.

Appreciate the confirmation.

Thanks mate, I tested this and it worked, pretty straightforward thats what confused me the most. It was too simple to configure so was wondering whetehr I was missing something.

Appreciate your response.

Cheers!

Hello,

Do you have any example configuration for standard GRE tunnel setup in 7750SR? I cant find one in the regular 7750SR configuration guides. Is it required to have a ISA module?

Thanks, Best Regards

You do not need an ISA card to create a GRE tunnel for a SDP. Here is an example of configuring the SDP over GRE:

configure service sdp <sdp-id> create
far-end x.x.x.x/x
no shutdown
exit

Then you will type in show service sdp and the list will show you the Delivery Method which will say GRE. The default configuration of a SDP is to be attached to a GRE tunnel. You have to change the command in order to bind it over LDP/RSVP. That would look something like configure service sdp <sdp-id> mpls create.

Specify the desired Transport/Delivery Type (in our case, GRE) when creating the SDP.

configure service sdp <$sdp_id> gre crete
