Guys.....Im trying to configure MLPPP link (over E1) between two Juniper
M10is in my test lab...and want to discover the possible load (CPU and
Memory) that can survive without any service intruption...but i got stuck in
one place...i have M10is with AS PIC installed. The scenario is very
simple....and i got success in creating MLPPP between all the routers but
one MLPPP fails...didn't allow me to PING interface IP....no OSPf...means
not functionining....folowing are the configuration and stats of those
routers,
*R1:*
interfaces e1-1/1/8
unit 0 {
family mlppp {
bundle lsq-0/2/0.2;
}
}

family inet {

}
}

}

Logs and stats shows MLPPP link is UP and Running but it wont work....from
R1 number of other MLPPP link are runining with the same configuration...but
with R2 this is the first MLPPP link..and it fails...this can be due to AS
PIC but AS PIC is just fine as there is no logs regarding AS PIC.....also i
am successfully runing GRE tunneling between R1 and R2 using the same AS
PIC.
Kindly check

Fahad
