Yes, it depends on what kind of isdn switch you are using. For the switch
configured with spid support or different numbers for each channel, you will
need two maps to bring up another channel by using ppp mulitlink and load
threshold.
ppp multilink enables bundling of two channels while load threshold define
how much extra traffic will bring up the second channels. Does it make
sense?

Subject: ISDN dialer map statements
Hi guys,
Does anybody know if there some kind of rule which governs dialer
configurations.? Quite often one can see different kind of configs when it
comes to enabling second B-channel under the load condition. Some people use
ppp multilink and one dialer map statement(I'm talking here about legacy
DDR).
Others (e.g recent lab from CCIE Bootcamp) use ppp multilink and 2 dialer
map statements with 2 different dialer strings. Does is it depend on the
type of isdn switch?
What is proper procedure?
I tried to test it in my lab, but it doesn't work either way. The second
B-channel just won't come up.
Thanks
Jan
