From: Tim Chown <Tim.Chown@xxxxxxxxxx> "https://tools.ietf.org/html/draft-ietf-mboned-deprecate-interdomain-asm-05#section-4.5. Preferring SSM applications intradomain If feasible, it is recommended for applications to use SSM even if they are initially only meant to be used in intradomain environments supporting ASM. Because PIM-SSM is a subset of PIM-SM, existing intradomain PIM-SM networks are automatically compatible with SSM applications. Thus, SSM applications can operate alongside existing ASM applications. SSM's benefits of simplified address management and significantly reduced operational complexity apply equally to intradomain use. However, for some applications it may be prohibitively difficult to add support for source discovery, so intradomain ASM may still be appropriate." > This wording was the result of comments received from those using ASM within their own networks. Indeed. Just to be clear about why some of us might be sensitive to the wording. RFCs get in the hands of many people involved with network development, including those in a purely management role. So, even if, in principle, intradomain, network designers can twist and stretch RFCs to suit their needs, as long as they break nothing, in practice, network designers are not always able to benefit from this unwritten rule. "It says right here that SSM is preferred," the manager will complain, not necessarily getting all the fallout. Happy New Year mboned!
