Does PPP "advertise" the /32 host route?
Couldn't find a better word than advertise so forgive me if it's inaccurate but while playing with PPP(authentication and enabling) I noticed some odd behavior. No routing protocol was enabled, yet the router at the other end of the point to point link had an entry in its routing table for the distant interface, a /32 route. Whats even wierder is that the IP addresses can be in totally different subnets, sharing the same link and still be pingable! Seems really buggy to me, how can this be and is there ever any use for to devices to share a point to point link using totally different subnet information and still be able to communicate?
