VPN tunnel with the BGP

[pcfreak49]

I have a question, you can establish a VPN tunnel with the BGP ?

[Marcin Latosiewicz]

Can you be a bit more specific?

You can use  BGP routing proto to route inside VPN, you can run BGP to connect to VPN endpoints. BGP is crucial to MPLS VPNs etc. :-)

okay it is possible to route between two remote routers with BGP

Hi,

Only situation where I have configured BGP routing through VPN (If that was what you meant), was abit "exotic"

I/We had a 1841 router with a Primary ADSL connection (routing to ISP with BGP) and 3G HWIC cards to handle Secondary connection. This was also routed with BGP.

We configured 3G -> Easy VPN -> GRE tunnel -> BGP routing

This way we basicly used to run BGP routing trough a VPN connection for the Secondary link also.This way if the primary link/BGP routing went down, the Secondary 3G link would take over.

the aim is to create a site to site vpn ipsec vpn tunnel

via an OSPF routing BGP like you can do

[TheTechCatalyst]

Can you peer over a tunnel?  YES.  In fact Core Transit is a tunnel based BGP enabled IP Transit provider of sorts.  Is it useful?  Maybe / maybe not.  It depends on what you're trying to do...

Yes, you can, as long as the route that you want to reach is installed in the routing table you can establish a VPN tunnel.
