hi
we have head and branch offices and we want to connect branches to head office with gre over ipsec vpn.
on branch sites have two provider link which connect to head office.
i configure gre over ipsec vpn on all cisco routers and configure dynamic protocol eigrp. i wish one link is primary and second link is back up.
i think that i do this with eigrp metric. when calculate eigrp metric we use bandwidth and delay in gre tunnel.
which one is more recomendate to configurate bandwidth or delay?
how i configurate them?
do i need offset?
please provide any configuration or configuration guide for this topology
thsnks.
