This question simply requires basic multicast setup between R5 and R6 using PIM sparse-dense-mode. If you have configured this correctly as shown in Example 1-65 and Example 1-66, you have scored 1 point. Example 1-65. R5 Multicast Configurationip multicast-routing ! interface FastEthernet0/0 ip pim sparse-dense-mode ! interface ATM3/0 ip pim sparse-dense-mode Example 1-66. R6 Multicast Configurationip multicast-routing ! interface FastEthernet0/0 ip pim sparse-dense-mode ! interface ATM1/0.99 point-to-point ip pim sparse-dense-mode
Configure ip igmp join-group 224.4.4.4 under R6 fastEthernet0/0. If you have configured this correctly, you have scored 1 point.
This question requires Stub Multicast Routing. This allows you to configure remote/stub routers as IGMP proxy agents. The stub router does not fully participating in PIM and, hence, is not seen as a PIM neighbor; access-list 11 blocks the neighbor. If you have configured this correctly as in Example 1-67, you have scored 2 points. Example 1-67. R6 Stub Multicast Configurationinterface ATM1/0.99 point-to-point ip pim neighbor-filter 11 ! access-list 11 deny 10.99.99.2 |
