I have configured multicast(ip pim dense-mode) on two 2911 that are connected by a Multilink( 3 Mbps) Wan connection.
The configuration works fine for awhile and sometimes all day but at some point one of the Multilink interfaces stops passing multicast traffic.
I perform a SH Multilink 1 on the interfaces and one show multicast packets incrementing and one does not, it just stops.
The problem acts like there is a buffer that gets full and after that happens it just stops working.
Has anyone heard of this or seen this issue before?
