All,
I'm working on an ipexpert frame relay practice lab. When you finish the lab
you end up having a physical interface with 4 DLCIs under it. All 4 DLCIs
point to the same Virtual-Template. The first two DLCIs point to 2 different
locations and the other two DLCIs point to a third location. (So the other
two DLCI's point to the same location.) One of the requirements is that
"only one /32 route to R2 should be seen on R6". To do this the lab has you
set "ppp multilink" under the virtual-template interface.
interface Serial0/1/0
encapsulation frame-relay
frame-relay interface-dlci 214 ppp Virtual-Template1 <-location #1
frame-relay interface-dlci 215 ppp Virtual-Template1 <-location #2
frame-relay interface-dlci 216 ppp Virtual-Template1 <-location #3
frame-relay interface-dlci 226 ppp Virtual-Template1 <-location #3
interface Virtual-Template1
ip address 150.200.200.2 255.255.255.0
ppp authentication chap
ppp multilink
I don't understand this.?.? Basically, all 4 DLCI's are under the virtual
template interface. Why doesn't the router try to take all 4 DLCIs under the
virtual template and bundle them together? If you had 4 physical interfaces
under a multilink interface that had "ppp multilink" under it the router
would try to bind all 4 interfaces together. right? How is it that the
router knows only to bind DLCIs 216 and 226 together?
Thanks,
Mod.
