RIF-passthru does just what it says. It passes on the RIF instead of
terminating it locally. In this case, the virtual ring must be the same
number on all peers.

Subject: Another silly question
> Hi group,
> I am learning dlsw but I have no physical token ring interface in my
routers. So don't laugh if it may be a simple question. I do not understand
the function of RIF passthru feature very well. What is the difference
between RIF passthru and RSRB? For example,
> ring#1---R1---R2---ring#2---R3---ring#3
> R1 and R2 are dlsw peers, R3 works as SR bridge. Then hosts on ring#1 can
visit those on #2 and #3. When the topology changes to
> ring#1---R1---R2---R3---ring#3
> |
> ring#2
> R1 to R2 is the same. R2 and R3 are connected via RSRB. I GUESS the three
rings can visit each other. But I am not sure if I need to configure two
ring-groups on R2 for dlsw and rsrb. Forther more, if change R2 and R3 to
dlsw peers, ring#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.
