Are you retarded? The release notes he is quoting are from 1998, anyone
who is still running 11.1(18)CC probably has bigger problems than their
peer groups. As for BGP templates, it has nothing to do with scale. BGP
templates are simply the newer and better replacement for the peer group
functionality, that adds more features and is less restrictive. Anyone
doing a new deployment should probably use the new system instead,
unless there is some specific reason not to (e.g. a noc which isn't
capable of learning new things, etc).
