ISDN BRI - not all channels are up

[ssidin]

Hi,

I've 4 ISDN BRIs at my branch used as a backup to the primary leased line, connected to HQ using PRI.

When activated, only 1 BRI (2 channels) are up, though I've configured so that all 4 BRIs are up. Is there any problem with my config? Should I use rotary-group?

interface BRI1/0 (to BRI1/3)

no ip address

encapsulation ppp

dialer pool-member 1

isdn switch-type basic-net3

no cdp enable

ppp authentication chap

ppp multilink

!

interface Dialer1

ip address x.x.x.x

encapsulation ppp

dialer pool 1

dialer remote-name hq-one

dialer string xxxxxx

dialer load-threshold 1 either

dialer-group 1

no cdp enable

ppp authentication chap

ppp chap hostname xxxx

ppp chap password xxxx

ppp multilink

thanks.

Hi,

Can someone confirm me about "ppp multilink links minimum" command? If I set the minimum as 8 (4BRI- 8 channels), and suddenly 1 BRI is faultly/not working for whatever reasons, will it affects the MPPP connection? Will the connection drops since only 6 channels (3BRIs) are up?

thanks.
