I have ospf on a 5510 active on the outside and inside interfaces both in ospf 1.
The outside interface is utilizing ospf for our failover scenario.
I am looking to implement md5 on the asa and inside routers.
My question is,
If I implement the md5 on the outside interface, does it set the authentication on all interfaces, or do I need to set each seperately?
I am concerned about loosing connectivity momentarily as we have an application from DMZ to inside that does not like to have the sockets hung open, and does not easily recover.
Can I globally set the MD5 authentication on all interfaces at the same time?
