how to configurate Site-to-Site VPN with GRE tunnel

[teymur azimov]

Hi dears,

I have ASA 5555-x and configurated site to site vpn. Now that our side wants to receive multicast messages from the other side. In this case i know that i must  configurate gre tunnel  on router. because asa is not supported gre tunnel.  i have also router 2811.

I know that  we need to add a cisco router behind the firewall in order to receive multicast messages.

configurate site to site vpn on asa and gre tunnel configuration on router. please provide me any documentation or link or example about this topology.

thanks

Dear Teymur you need configure both Asa with site to site vpn and after that you can configure gre tunnel on subnnet that in local lan space via this lan in both side you can configure gre tunnels/ that's mean both router in your lan side have local ip address and can ping each other. via this local interface you can attach tunnel interface to interface that see asa lan side.

branch office connect two physical link to head office with vpn. i used eigrp at branch router so the traffic is going to head office via vpn on  one link when this link is down the eigrp metric is working and the traffic isis going the second link.

how i configurate eigrp process on brach router?

You need do eigrp process working with primary link if this link is down when eigrp can reroute traffic via second link.

You need use offset feature or bandwith feature foe control eigrp process.
