Default route over IPSEC VPN router to router

[juan-ruiz]

                   Hi guys,

If someone can please share a link this would be great on the topic of site to site IPSEC VPN using routers and default routing.

I have three routers, router A,B,and C.

A and B are connected over an MPLS and C is on the internet.

B and C are connected over a site to site IPSEC tunnel and now I want to advertise from C to B the default route only.

A has sent all of the routes B needs for the subnets over the MPLS but now I want to push the default route 0/0 to the IPSEC tunnel and come out of the C router.

Thanks in advance

Regards,

Juan

You need a GRE tunnel to do that, not IPSEC.

ok great yes I know that but I was wondering if I can source route my LAN to use the remote Cisco router as the default gateway for internet using RRI but probably not and GRE or DMVPN is the way to go but I will wait for your reply on this.

thanks again for your response.

Kind regards,

Juan

As above, use GRE.

Thank you for the nice rating and good luck!
