ICMP unreachables (was: Watcher page moved...)

[atr () netmaine com (Andrew T. Robinson)]

Am I mistaken in my belief that a router attached to a single Internet 
connection

a) Does not require anything other than a static default route and
   BGP/EGP advertisements of internal routes?

b) Should ignore all ICMP redirects addressed to it

c) Should drop all ICMP redirects in general, as there is only one
   path out of the next and a downstream site should handle the "real"
   routing

????
