HO have two internet links one LL (connected to asa ) and one ADSL.(connected to pix)
DR having one internet ADSL. (connected to asa)
Now i have a site to site from LL ho to adsl DR. i want to configure another tunnel from the ADSL HO to ADSL DR.
when the second tunnel comes up the DR ASa will have two tunnels to two sperate public ips with the same crypto and no nat acls since the source and dest internal networks to be protected are same for both the tunnels
is this possible and if both the tunnel comes up which tunnel the asa in the dr will send traffic to and is there any other solution this cane be made to work
Yes you are correct...... HO has 2 internet links in which one is via leased line and other one via ADSL..... LL/ASA will have a L2L connectivity to DR and ADSL/Pix will have L2L connectivity to DR, which is a normal scenario.
On you DR, you need to configure 2 Peers as stated in blogs in the same crypto-map.... peers....
1st Ip will be primary and second peer ip will be standby... if primary fails, then traffic will be thru secondary peer... i.e. via ADSL....
