irule to disable interface
Trying to come up with a work around for not having BFD implemented between LTM and router in imish. Goal is to have interface shut down if far end of interconnect becomes ICMP unreachable. If far end becomes reachable, enable interface. I'm thinking I can do this in the Linux OS with a perl script, but any thoughts would be appreciated.
