Nexus FabricPath on nexus7k and nexus5k with fabricpath authentication

This is a config template for fabricpath configuration with fabricpath isis md5 Authentication

so i have configured the dual links in LACP port channeling and enabled fabricPath on the port-channel with authentication (md5 authentication with key-string as "fabmd5" )

Outputs/verifications after the config are down
