Re: peer groups inside a RR cluster ..any restrictions ????

Hi.

Apparently you are reading something outdated.

      Limitations of Peer Groups

Cisco IOS Software Releases earlier than 11.1(18)CC have the limitations
described in this section. Failure to adhere to these rules can result
in inconsistent routing.

    *

      If you use peer groups for clients of a route reflector, all the
      clients must be fully meshed.
