The device has two IPSEC tunnels setup for each external IP of "outside" and "Backup".
If we fail the outside ISP, we have successful failover to "backup" ISP.
SOMETIMES, the return to the primary ISP "outside" does not work properly. The OUTSIDE interface will become primary, but the IPSEC tunnel will not come up. Doing a "shut" on the ASA's e0/0 interface will fix this.
Anyone seen this weird behaviour before? once the shut/no shut on e0/0, the Ipsec tunnel will come up.
Did I miss something with the RTR ans SLA commands?
We have configured the outside and inside Interface with official ipv6 adresses, set a default route on outside Interface to our router, we also have definied a rule , which also gets hits, to permit tcp from inside Interface to any6.
In Syslog I also se...
