Add an iRule to multiple virtual servers

Hmm, that's what I expected it to look like. Let's work through this iteratively then.

tmsh list /ltm virtual |grep "ltm virtual"

That should give you something like this:

ltm virtual vip_oid.s2boss.corp.xxxxxxxxxxxxxxx.com {

If you see several lines that look something like this, then add the AWK back in:

tmsh list /ltm virtual |grep "ltm virtual" |awk -F" " '{ print $3 }'

The idea here is that you're taking this returned line, splitting it on the empty space, and extracting the third element, which should be the VIP name. Give that a try.
