# On RB 2, perform the following tasks on access-facing interfaces VLAN-interface 10 and
VLAN-interface 20:
{
Assign an IPv4 address to the interface.
{
Create an IPv4 TRILL VR and assign a virtual IPv4 address to the VR.
{
Enable IGMP and PIM-SM.

[RB1] vlan 20
[RB1-vlan20] igmp-snooping enable
[RB1-vlan20] igmp-snooping drop-unknown
# Configure RB 2 through RB 6 in the same way you configured RB 1.
6. Configure TRILL distribution trees:
# Set RB 1's priority to 65535, and set the number to 2 for TRILL distribution trees that the RB wants
all RBs to compute.

# Set RB 2's priority to 65534, and set the number to 2 for TRILL distribution trees that the RB wants
all RBs to compute.
