Based on the configuration in the exhibit, which routing table is used for IPv4 multicast RPF
checks?
A.
inet.0
B.
inet.2
C.
foo.inet.0
D.
inet.8
The answer is inet.2
inet.2—For subsequent address family indicator (SAFI) 2 routes, when multiprotocol BGP (MBGP) is enabled. This table stores unicast routes that are used for multicast reverse-path-forwarding (RPF) lookup.
seems B is right based on this link? http://kb.juniper.net/InfoCenter/index?page=content&id=KB16133
The answer is- inet.8
gov@SRX1# run show multicast rpf
Multicast RPF table: inet.8 , 0 entries

D is correct (inet.8)
http://www.juniper.net/techpubs/en_US/junos15.1/topics/example/multicast-pim-rpf-rib-group-configuring.html
Only the first rib routing table specified in the import-rib statement is used by PIM for RPF checks.
