Dear All,
I use XORP for PIM-SM only. On my FreeBSD, the MRIB entries are coming
from the kernel routing table as below.
DestPrefix NextHopRouter VifName VifIndex MetricPref Metric
10.1.1.0/24 10.1.1.100 fxp1 1 0 0
10.10.1.0/24 10.1.1.1 fxp1 1 254 65535
10.20.1.0/24 10.20.1.1 fxp0 0 0 0
I am wondering why the Upstream MRIB next hop (RP) is always UNKNOWN?
Below is the (truncated) results of show pim join. (I typed the line numbers)
Thank you,
