Hi,
You can only configure DLSW+ or RSRB but not both at the same time. If you wan
t your second design to work, using DLSW+, then peer R1 to R3 and R2 to R3.
I hope this helps.

So don't laugh if it may be a simple question. I do not understand the functio
n of RIF passthru feature very well. What is the difference between RIF passthr
u and RSRB? For example,

gs can visit each other. But I am not sure if I need to configure two ring-grou
ps on R2 for dlsw and rsrb. Forther more, if change R2 and R3 to dlsw peers, ri
ng#1 cannot visit #3 since R1 and R3 are not peers. I wonder if configuring RIF
passthru for R2 and R3 can make hosts on ring#1 visiting #3.
