I have a public ip on my loopback and thought this was what ios preferred if it exists? I have some other interfaces which have 10.x.x.x addresses and icmp messages like host unreachable and such are sourced from this which is undesirable due to inbound filtering at many sites at their gateways for rfc1918 and other bogon addresses. Am I being silly to want this or is there something I can do to get my way here? Tks.
