Re: SNMP vs 1.1.1.1 (fwd)

["Michael F. Nittmann" <nittmann () wis com>]

just to cut that 1.1.1.1:

packets like trumpet etc. make 1.1.1.1 the default before negotiation.
If a dial up user gets on a PPP port where his address is not negotiated, 
but accepted, the (trumpet, winsocks etc) default wil lkick in.

That's where 1.1.1. comes from: a dial in port is improperly configured 
to accept the offered dial-up customer address, instead of negotiating it.

Most comservers I know have the flag 'negotiated' for PPP adress and 
should sit there.

Next config error is then to accept incoming routes from PPP connections 
and to propagate them through the network, even over to other peers.

This does not occur with the other frequent default of 0.0.0.0 since most 
braindamaged equipment 'thnks' subnet 0 is 'unusable'.


1.1.1.1 only shows up if something is not configured right on the 
provider side.
