[j-nsp] PIM join Upstream Unknown

[Andrew Jimmy]

When will you get Upstream interface: uknown? PIM-dense-sparse  mode has
already been enabled on all interfaces. All the IPs are accessible from each
router and end clients. There is no connectivity or route reach-ability
issues between routers or multicast source/receiver. 

 

Multicast source is: 192.168.0.1

 

I don't know why the heck I'm getting Upstream interface Unknown on PIM
join..

 

Here is show multicast rpf on receiver end router:

 

1.1.1.1/32

    Protocol: OSPF

    Interface: lsq-1/3/0.1

    Neighbor: (null)

 

192.168.0.1/24

    Protocol: OSPF

    Interface: lsq-1/3/0.1

    Neighbor: (null)

 

Here is show pim join:

 

Group: 227.12.22.33

    Source: *

    RP: 1.1.1.1

    Flags: sparse,rptree,wildcard

    Upstream interface: unknown (no nexthop)
