Hello,
please excuse beginner questions.
We have two distant EX4200 connected via 10G uplink module. The 10G interfaces are IP interfaces.
Now we managed to get another link, from other operator, and we would like to use it as backup link between these two Junipers. But in a way, that only one at a time would be active. And in case of link failure, it would switch to other link.
xe0 ----main link---- xe0
xe1 ----backup link---- xe1
If we use RSTP, we would have to manually change IP address from xe-0/1/0 to xe-0/1/1
If we use LACP, it will use both links and load balance the traffig among them. One of our customers sends 1G of multicast transport stream over this Junipers and he says, that load balancing causes them big troubles with jitter or what.
Can we somehow combine RSTP and LACP? So both 10G interfaces would act like one interface with one IP address and always only one active link?
Or can we somehow configure LACP, so it will not do load balancing and use only one link at a time?
And one more question: When the link from our operator fails, it usually does not turn off. It usually stays active. Is this problem with RSTP or LACP? I mean, will it recognize that the link failed, even if the port doesn't turn off?
Thank you for your patiance with me
