EIGRP - Extended NAMED ACLs are not allowed in distribute-list.

Quick post regarding an error message I came across when trying to configure eigrp distribute-list with extended NAMED ACLs.

% The ACL cannot be created or an ACL with the same name but incompatible type already exists.

Router version CSR1000v - Cisco IOS Software, CSR1000V Software (X86_64_LINUX_IOSD-UNIVERSALK9-M), Version 15.4(2)S, RELEASE SOFTWARE (fc2)

However, numbered extended ACL works just fine.
