Hi, there
Let's analyse. Remember tunnel is just a virtual path based on unicast
routing table.
1)If two paths between R3 and R5 are equal in unicast routing table. You
don't have to enable multicast path R3-R2-R5, since tunnel will
automatically be load sharing between 2 unicast paths.
2)If path R3-R2-R5 is better than R3-R1-R5 in terms of unicast routing,
tunnel will go through R3-R2-R5. Then there will be no load sharing. All
multicast traffic will go through R3-R2-R5. Tunnel is useless.
3)If path R3-R1-R5 is better than R3-R2-R5 in terms of unicast routing,
tunnel will go through R3-R1-R5. Then R3 and R5 both need ip mroute to point
to tunnel. Since R3 will choose better path to forward multicast traffic,
which is the tunnel. There will be no load sharing.
Best Regards,
Net (Xin) He
