yes see that's what I thought and this is what's confusing me...
when I go under the dialer1 interface all I see is this
BLKLANSTR01(config-if)#ppp chap ?
hostname Set alternate CHAP hostname
password Set default CHAP password
refuse Refuse to authenticate using CHAP
wait Wait for caller to authenticate first
and when i go further like under hostname and so on I don't see anything that implies a "username and password" to be used for pppoe authentication. So I'm thinking I must be in the wrong place. Very strange this 880 is.
actually with ppp hostname you specify how your router presents itself to the PPP peer.
ppp chap hostname
To create a pool of dialup routers that all appear to be the same host when authenticating with Challenge Handshake Authentication Protocol (CHAP), use the ppp chap hostname command in interface configuration mode. To disable this function, use the no form of this command.
ppp chap hostname hostname
no ppp chap hostname hostname
The name sent in the CHAP challenge.
So the commands look like correct and you need to use the parameters that your ISP has given you.
hostname: because the PPP authentication appears between two routers the default name is the router hostname.
And the username password command in global config is used to define the other router's hostname and password is the same (but this is bidirectional authentication that happens on both side)
So actually this is the correct way to configure CHAP on an ISP connection where the caller (your router is authenticated) ppp authentication chap callin
