一、问题

在r3和r1之间使用了GRE通道，所有的路由器接口配置为sparse-mode,R4 ip为（1.1.4.4）但Ｒ１无法ping通多播源。

二、示意图如下

multicast source -----R5------R3-------R223----R1--e0

............................................

............................................

............................................R4

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

三、原配置如下

R1#mtrace 1.1.15.1 150.100.2.1 239.255.8.8

Type escape sequence to abort.

Mtrace from 1.1.15.1 to 150.100.2.1 via group 239.255.8.8

From source (?) to destination (?)

Querying full reverse path...
