Hello everybody,
I have been configuring Auto-RP and BSR in the following topology:
(R1)---FR----s1(R2)s0----FR----(R3)
I wanted R1 to be the RP for 224.0.0.0/5 and R2 to be the RP for
232.0.0.0/5. There is no split horizon limitation in this topology because
R2 uses 2 different interfaces.
When configuring BSR:
- R3: BSR candidate
- R2, R1: RP candidates
Everything worked great with BSR.
When configuring Auto-RP:
- R3: RP Mapping Agent
- R2, R1: RP candidates
Only R2 could become RP. R1's announcement didn't come to R3.
I had to create a tunnel between R1 and R3 to take the R1's announcements to
R3 and then everything worked.
Now i would like to show you my deductions in order to be corrected:
BSR in a NBMA network allows communication between BSR and RP candidate
without sharing the same Layer 2 segment.
BSR in a NBMA network doesn't allow communication between RP Mapping Agent
and RP candidate without sharing the same Layer 2 segment.
But then why a tunnel will solve this requirement?
I would like to read more about this topic. Could somebody tell me about a
good link that explains and compares Auto-RP and BSR?
Thanks a lot for your help
